Fluoride - Demand AARP Take Action

“The evidence that fluoride is more harmful than beneficial is now overwhelming… fluoride may be destroying our bones, our teeth, and our overall health.” - Dr. Hardy Limeback,  former President of Canadian ADA, Head of Preventive Dentistry at Univ of Toronto, 2006 National Research Council Scientist (2007)


The 2006 National Research Council on Fluoride in Drinking Water commented to the EPA that fluoridation at 1 ppm can be anticipated to be harmful for those with reduced renal function and the elderly. The NRC confirmed that fluoride not excreted by kidneys builds up in bones, resulting in arthritic pain and increased brittleness. However, there were no EPA studies on the whole health impacts of fluoridated water on susceptible population such as kidney patients, children, those with prolonged disease or the elderly. There still aren’t. 


However, there is mounting science from other sources that “optimally fluoridated” water, which is known to cause varying degrees of dental fluorosis in 58% of Black American adolescents and 36% of White American adolescents, is causing subtle deficits in ability to remember or focus. That same “optimal level” has also been proved in a 2014 study as being nephrotoxic in rats with chronic kidney disease. Chronic kidney disease (CKD) affects approximately 15% of Americans, although CKD is quadruple the rate in Black Americans, and predictably worse in older Americans. 


Perhaps the most horrifying part of the story of fluoridation is that not only is at least 50% of every drop of fluoride that has passed the lips of a Baby Boomer permanently stored in bones, fluoride isn't the only poison in packages of fluoride that originate as the waste product of aluminum an phosphate industry. 100% of the fluoride sampled in a 2014 study was contaminated with aluminum; arsenic and lead were other common contaminants. In other words, fluoridated water serves as a delivery system for aluminum and lead into our bones and our brains. As we all know, aluminum is associated with Alzheimers in adults, and lead is associated with learning disabilities in children. Approximately 15% of the population who is sensitive to chemicals cite inability to think clearly and overwhelming fatigue as symptoms of exposure to fluoridated water. 


Our generation was part of a great human experiment. It may have had noble intentions based on the faulty hypothesis that  drinking fluoridated water prevented cavities. It is now known that any perceived benefits of fluoride are from tooth brushing.  Our grandchildren are the third generation in this travesty. I suggest we all DEMAND the AARP stand up for us and our grandchildren by issuing a strong position paper calling for the cessation of water fluoridation.

Yes, as I said, the daily upper limits for infants and children ages 0-8 are considerably lower than the 10 mg per day limit above the age of 8.  The reason for this is due to chance of mild dental fluorosis during the teeth developing years of 0-8.  Mild dental fluorisis is a barely detectable effect which causes no adversity on cosmetics, form, function, or health of teeth.  As peer-reviewed science has demonstrated mildly fluorosed teeth to be more  decay resistant, this effect is considered by many to not even be undesirable, much less adverse.  


Those parents who are concerned with mild dental fluorosis, in spite of the increased decay resistance of these teeth, may certainly avoid using fluoridated water for their children during these years if they so choose.  Otherwise, there is no need to do so.  There is  no valid evidence to support the claim that the “desired level should be zero”.  Nearly any substance in the bloodstream other than perhaps plasma and blood cell components, could be considered to be a “contaminant”.  This obviously does  not mean that the desired level for all substances is zero.


There are no “proven” adverse effects on the brain, bones, or any other bodily system, from optimally fluoridated water.  The National Academy of Medicine does not concern itself solely with  dental fluorosis.  If there was a concern for any other adverse effects of fluoride in infants and children,  the NAM upper limits for daily fluoride consumption would reflect this......and, this limit would not jump to 10 mg at age 8 if there were concerns other than dental fluorosis.


Optimally fluoridated water has no adverse effect on bone.  Even long time fluoridation opponent Hardy Limeback reported this finding in a 2010 study he co-authored.


“ While we cannot definitively rule out an effect of low-level fluoride accumulation over long periods of time, especially if specific individuals have a genetic or disease background that renders them unusually susceptible to fluoride, it nevertheless appears that the contributors to bone health are too many and varied, and any possible effect of municipal fluoride ingestion is too small, for municipal water fluoridation to be a significant determinant of bone health within the general public”

Thank you for your professional response.


What do you consider to be the upper limits of fluoride ingestion for infants and children?  (SAFE)


What dosage of fluoride is required or recommended to prevent dental caries? (EFFECTIVE)


References please. 



One area of communication which breaks down between us is consideration of the contribution of fluoride from fluoridated water versus total fluoride exposure.  I would mostly agree with you on risks from fluoridated water. . . if fluoridated water were the only source of fluoride. 


However, I have never seen studies comparing fluoridated water with no fluoride exposure.  Just not possible because fluoride comes from many sources and fluoridation usually contributes between a third to two thirds total individual exposure. 


Therefore, a statement claiming "There are no “proven” adverse effects on the brain, bones, or any other bodily system, from optimally fluoridated water," has several serious problems. 


1.   Studies are not possible.   Sort of like saying that there are no "proven" adverse effects living on Mars.  The problem is obvious, no one has been there.


2.  The statement is intentionally trying to decive the reader, or is not taking relative source contribution, total exposure seriously.  Water fluoridation is only one source of fluoride.  And not everyone drinks the same amount of water, swallows the same amount of toothpaste, eats the same amount of fluoride in food, etc.


3.  The word "proven" is troublesome when evaluating risk, and I presume that is why you used the word in quotations.  We can do RCT studies of benefit, but RCT studies on risk are not ethical.  In the end, risk is a judgment call.  Sort of like driving fast in the mountains, going around a curve can have risk and the driver needs to use judgment based on all factors of road conditions, traffic, car and driver etc.   The same with chemical risk.  Not all humans have the same tolerance for chemicals.  Age, kidney function, dosage, synergistic effects, and a host of other concerns for each individual.  To "prove" harm for an individual, we would need to harm them, which is not ethical.


4.  The judgment of "proof" for chemicals such as fluoride requires weighing all factors such as degree of freedom of choice, degree of benefit, degree of harm, and total dosage.  All three areas are complex and need a "global" consideration.


From a Public Health standpoint, if the lack of fluoride caused/permitted a highly contagious lethal disease, certainly mass medication should be considered.  (Courts have been reasonably consistent giving Public Health strong police powers for quarentene, treatment, etc.)   Caries is not considered highly contagious or highly lethal.  Yes, bacteria moves from one person to another and a few die from oral infections.  But everyone (probably) has the bacteria in their mouths and deaths are extremely rare.   Indeed, Public Health officials will force medication or isolate the contagious individual to protect the public.  We do not isolate a person with dental caries from the rest of the public.


Would we consider going house to house and requiring each person to swallow a fluoride supplement pill to protect the spread of dental caries?  No.  Well, that is preciesly what water fluoridation does.  Goes house to house, with police powers, and gives each person an additional Rx dose of fluoride without the person's consent.


Nor would we consider removing those individuals who refuse the Rx fluoride supplement from their homes and isolating them from others in the community.

Ethics of fluoridation are problematic. 


Before we even consider the evidence of risk, we must determine the dosage needed to prevent dental caries.  Once the dosage needed to prevent caries is determined, then we need to determine whether that dosage is safe.

Just terriffic, a bunch of YouTubes to justify opposition to what the CDC considers one of the great accomplishments in public health in the 20th Century.

Fluoridationists love to tear apart any study that dares to taint fluoride in any way. I think we can all do that with any study because science is never settled.


I think it's time to look at the studies which gave birth to fluoride use for dental decay


The Kingston/Newburgh; Grand Rapids/Muskegon and others were the first experimental cities used to test the hypothesis that ingested fluoride via the water supply safety reduced tooth decay.  Both Newburgh and Grand Rapids were fluoridated.  The trials were set to last from 10 - 15 years but were cut short after only about five years - before the teeth of those born into the experiment had even erupted.  Newburgh was the only city to look at health effects.  Preschoolers and adults weren't studied and long term effects never considered.  


Dr. Hayne, Slott and Johnson - please tell us why those early fluoridation studies are valid by today's standards - or even by the standards of 1945 when they began.


Thank you for your consideration

Here are fluoridationists Steven Slott and Johnny Johnson on YouTube:


"...the political profluoridation stance has evolved in to a dogmatic, authoritarian, essentially antiscientific posture, one that discourages open debate of scientific issues." - Dr. Edward Groth, III, Senior Scientist at Consumer Union (1991) 


The most interesting thing about that video of the presentation by JJ & SS originally used in Green Bay is that slide that JJ quickly goes past claiming it lists claims by opponents that are ALL FALSE. This misrepresentation of the opposition position is known as the 'straw man fallacy.' It is a rhetorical deceit. In a subsequent presentation in Cortland, JJ did spend a few minutes misrepresenting a couple of those points. 


I took a screenshot of that slide in order to actually read it. 


  • Not only does the WHO data verify the 20th global decline of cavities regardless of fluoride status of water beginning before fluoridation and continuing after some fluoridated communities ceased fluoridation, it has been reported on in multiple journals. Sadly, 21st century data shows an increase in cavities in several countries including America & Canada, even in long fluoridated communities. Fluoridation was coincidental, not causal. (Diesendorf 1986; Colquhoun 1990, 1997, 1999; Künzel 2000; Maupomé 2001)


  • Technically you can't be allergic to fluoride since it is a poison, but yes allergic type reactions are well documented and previously addressed in this thread.


  • Ditto for thyroid problems. They are not only very well documented as being caused by or exasperated by fluoride, many fluoride doctors advise patients avoid fluoride - despite the ATA's silence on the topic. I have it on good authority that they don't want to provoke a political storm with other groups - cowards. 


  • The derisive reference to the "2012 Harvard study" that lists fluoride as brain poison ignores not only the EPA scientist characterization of fluoride as a 'gold standard developmental neurotoxicant' (Mundy et al. 2009; 2015), it also ignores the recent high quality studies by American and Canadian researchers with expertise in neuortoxicity (Bashash et al. 2017; Thomas et al 2018; Yu et al 2018; Choi et al. 2015) There are dozens of human and hundreds of animal studies that find fluoride neurotoxic - even in low doses consistent with fluoridation. Only a handful claim not to find evidence of harm, and I believe every one of those few have been found to have serious design flaws. 


  • The 2015 Cochrane Review, like the 2000 York Review, didn't say fluoridation didn't have an effect, they said the effect was small and there not only was no evidence of safety, there was evidence fluoridation significantly increases dental fluorosis, plus the studies claiming benefit were all low quality and at high risk of bias, so they had low confidence in those findings of benefit. They also opined the relevance of fluoridation in the 21st century was doubtful. I believe it was that last statment that JJ and company managed to lobby the Cochrane to drop from their evaluation - an exceptional feat of interference with an independent review by lobbyists. 
    • Here's how the 2000 York Review senior scientists responded to similar attacks on their research: "It is particularly worrying then that statements which mislead the public about the review's findings have been made in press releases.... The review did not show water fluoridation to be safe. The quality of the research was too poor to establish with confidence whether or not there are potentially important adverse effects in addition to the high levels of fluorosis." - Professor Trevor Sheldon, chair of Advisory Board of 2000 York Systematic Review of Water Fluoridation, Head of Dept of Health Studies, University of York  (2003)
    • 2015 Newsweek article w/comments from scientists on meaning of Cochrane Report


  • "ChildSmile" - how is this one word "false" - it's a reference to alternatives to fluoridation that are effective at reducing cavities in populations of poor kids without adding uncontrollabe doses of this drug to municipal water. 


  • "Pharmaceutical Grade" - again, how is this "false" .... what it alludes to is that the chemicals added to our water are contaminated waste products of industry, invariably contaminated with aluminum, lead, arsenic, etc. (Mullenix 2014)

  • Fluorosis of teeth is a sign of toxicity. Well, yes.... dental fluorosis is the evidence of cell death during formative stages of tooth development. There is substantial evidence of other toxic damage during this same period. But just on teeth:

    • “Enamel fluorosis is a developmental disturbance caused by intake of supraoptimal levels of fluoride during early childhood.The enamel defects consist of horizontal thin white lines, opacities (subsurface porosities), discolorations, and pits of various sizes. The molecular mechanism underlying enamel fluorosis is still unknown.…. We can hypothesize that fluorosis is due to a combination of direct cytotoxic effects causing cell death, the delayed development of tight junctions, which are necessary to form a sealed barrier between apical and basolateral surfaces, and a direct inhibitory effect of fluoride on vectorial calcium and/or bicarbonate transport.” - Rácz et al., 2017


I could go on down the list - but here is that deceptive slide that JJ flashed in a sleight of hand attempt to deceive his audience.  

Deceptive Slide - Strawman MisrepresentationDeceptive Slide - Strawman Misrepresentation



The AFS VP, Myron Allukian, doesn't usually comment online - but he uses his connections at Harvard to engage others as shills in endorsing policy and parrotting marketing bullet points. He's been promoting fluoridation since the 1960s. The latest copy and paste by AFS Communictions Officer, is a document from those the VP and his associates duped into compliance.


Everyone at Harvard does not agree with that prepared statement.  

Neither do experts in other prestigious institutions. 


Expert in Neuroscience: “Prevention of chemical brain drain should be considered at least as important as protection against caries.” - Dr. Philippe Grandjean, Chair of Environmental Medicine at the University of Southern Denmark and Adjunct Professor of Environmental Health at Harvard School of Public Health (2014)


Expert in Neuroscience & Behavioral Psychology: There’s no doubt that the intake of fluoridated water is going to interrupt basic functions of nerve cells in the brain, and this is certainly not going to be [for] the benefit of anybody……The addition of fluorides to drinking water was, and is, a mistake.” - Dr. Robert Isaacson, 2006 National Research Council panelist on Fluoride in Drinking Water (2007)


Expert in Dental Public Health: “I now realize that what my colleagues and I were doing was what the history of science shows all professionals do when their pet theory is confronted by disconcerting new evidence: they bend over backwards to explain away the new evidence. They try very hard to keep their theory intact — especially so if their own professional reputations depend on maintaining that theory……..It is my best judgement, reached with a high degree of scientific certainty, that fluoridation is invalid in theory and ineffective in practice as a preventive of dental caries. It is dangerous to the health of consumers.” - Dr John Colquhoun, former chief Dental Officer of Auckland, New Zealand (1998)


Expert in Legal Analysis: “The cessation of all compulsory water fluoridation schemes should be the goal of all public health agencies, ethical lawmakers, and informed citizens.” - Prof. Rita F. Barnett-Rose, J.D. at Dale E. Fowler School of Law, Chapman University (2014)


Expert in Pediatric Sensitivity to Pollutants: “This is a very well-conducted study, and it raises serious concerns about fluoride supplementation in water” - Dr. Leonardo Trasande, a pediatrician who studies potential links between environmental exposures and health problems at New York University Langone Health on Bashash et al. (Sept 2017)


Dean of Public Health at University of Toronto: “We tested for all the things we could think of that could act on neurodevelopment. But we haven’t found anything else that was a potential confounder...Our study shows that the growing fetal nervous system may be adversely affected by higher levels of fluoride exposure. It also suggests that the pre-natal nervous system may be more sensitive to fluoride compared to that of school-aged children… to say it has no relevance to the folks in the U.S. seems disingenuous.- Dr. Howard Hu, Dean of the Dalla Lana School of Public Health at the University of Toronto on Bashash study for which he was the lead investigator (2017) 



Bronze Conversationalist

It was stated here that fluorosis does not adversely affect the health of teeth. Really? Normal teeth enamel is a layer that protects underlying bony dentin from exposure to the oral environment. Fluorotic hypoplasia refers to the fact that the enamel covering is not as thick as normal in the discolored area. Long term teeth protection requires normal thick enamel, not a thinned layer that cannot possibly last as long as a thick layer throughout a person's life. 


The Kumar data and others do not ever demonstrate that fewer caries exist in teeth regions that are fluorotic that is ever larger than experimental error. The less enamel covering there is, obviously the less protected the tooth is.


As far as Limeback arguing there may not be adverse bone symptoms due to lifelong consumption of fluoride water, there are no people in the U.S. who have ever been exposed to fluoridated water for the average human lifespan of 75 years yet (the practice only started in 1945). Further, as a participant in the NRC report he was complicit in the textual statement that bone fluoride levels in areas drinking 1 ppm F water are around 2,500 mg/kg while not stating the very data shown in the accompanying table that indicated bone pain in persons having bone fluoride levels below that (around 1,700 mg/kg). It's amazing how one can see what one want to see and not see what one doesn't want to see. The NRC study was not allowed to investigate water fluoridation at 1 ppm, so if you don't look at the raw data you may be trapped by the misjudgments of those who too cursorily summarize the data.


And there is no mechanism to assess bone strength in vivo in a person who has consumed fluoidated water for decades, so the effect that any fluoride accumulated amount has on bone is determined by analyzing the structure of fluoridated bone at various concentrations in vitro. There is zero doubt that fluorotic bone is abnormal bone becaue it is a perturbant that induces formation of bone of abnormal unit size and shape.


Blood comonents are all known and are published in the Merck Manual and most all Nursing Texts where each component has a known specific physiologic function. Fluoride has no physiologic function and is thus only a contaminant and of course is not listed as a required normal blood component in any reference source. It is not a nutrient and has no place in human blood, as stated previously.

“The Texas GOP’s official opposition to fluoridation is another example of the diversity of support for our movement.   From Ralph Nader, the Green Party's presidential candidate in 2000, to Libertarians like Dr. Ron Paul, to Democrats and Republicans at every level of government, and everything in between in countries with multi-party systems.  Opposition to fluoridation is clearly an issue we can all proudly find agreement on.” - Stuart Cooper, FAN Campaign Director (2018) 


Politics make strange bedfellows. Regardless of whether you self-identify as 'conservative' or 'liberal', no one wants to suffer from arthritis or dementia in old age. No one chooses decades of restrictions because of irritable bowel or kidney disease. No one wants to see their children struggle with learning disabilities or hide their smile because of embarrassment over stained teeth. No one wants broken bones because fluoride accumulation weakened them. 


And no one wants to be bullied by arrogant doctors who use political campaigns and social media in order to establish fluoridation mandates that force contaminated product into the bodies of convenient consumers regardless of the adverse impact on individual health! 


See Erin Brockovich's Position on Fluoridation:

In addition to the dosage issue, which is impossible to control, water saturation of 0.7ppm-1.2ppm silicofluorides does not mean dosage. Dosage depends on how much fluoride anyone is exposed to daily. This includes drinks, food that has been exposed to fluorides in the water, bathing, dental products, and so on. It is obvious that no-one can determine exactly how much fluoride anyone ingest or absorbs daily. So, how is this 'opminum level' nonsense anything other than a red herring issue? The 'optimum level'  babble is truly the biggest nonsense, which should be obvious to anyone, even with a fluoride damaged brain. Also, who gave some dentists a medical license to practice internal medicine or medicate the entire public without regard to individual conditions? These fluoride promoters are not the personal physicians of the entire public!


To All,


The Fluoride Action Network has the largest compilation of fluoride research available and I can highly recommend reviewing for your consideration.


Another significant source of research is the IAOMT at


Of the many pages of research and topics raising concerns with fluoride use, here are a sampling:


“The recommended Maximum Contaminant Level Goal (MCLG) for fluoride in drinking water should be zero.”  Carton RJ. Review of the 2006 United States National Research Council Report: Fluoride in Drinking Water. Fluoride. 2006 Jul 1;39(3):163-72.  


Carton worked at the EPA for many years.


“The ‘optimal’ intake of fluoride has been widely accepted for decades as between 0.05 and 0.07 mg fluoride per kilogram of body weight but is based on limited scientific evidence.”
“These findings suggest that achieving a caries-free status may have relatively little to do with fluoride intake, while fluorosis is clearly more dependent on fluoride intake.”  Warren JJ, Levy SM, Broffitt B, Cavanaugh JE, Kanellis MJ, Weber‐Gasparoni K. Considerations on optimal fluoride intake using dental fluorosis and dental caries outcomes–a longitudinal study. Journal of Public Health Dentistry. 2009 Mar 1;69(2):111-5. 


Many know these authors who are strong promoters of fluoridation.  Even the dosage of fluoride is based on limited scientific evidence.  EPA has also chosen 0.06 mg/kg as their RfD or reference dose. 


Consider a 5 kg or 12 pound infant.  At 0.06 mg/kg the "optimal" intake would be about 0.3 mg of fluoride a day.  Infant formula made with public water would be less than 2 cups of milk for the infant.. . not enough.  Mother's milk contains no detectible fluoride in most samples.


Knowing infants on fluoridated water get too much fluoride, the EPA does not even include infants in their Dose Response Analysis or Relative Source Contribution.   I disagree.  If governments send out fluoride to everyone without their consent, the EPA needs to include everyone in their determination of what is safe.

Dr. Osmunson lists "information" sources which have been specifically created to politically oppose fluoridation.

Legitimate scientists are only committed to being true to the available objective information.  If fluoridation were either dangerous or worthlessly effective America's Pediatricians and their medical, dental and scientific colleagues would speak out and fluoridation would cease.

The truth is that there is overwhelming support these legitimate professionals and scientists advocating community water fluoridation.

Here is an editorial from the Portland, Oregonian which speaks to the many arguments brought against community water fluoridation the Oregonian said:

"To believe such crackpottery is implicitly to believe the following: That state and federal health agencies are, for some mysterious reason, hiding the truth and helping to poison more than 200 million citizens, aided by the American Dental Association and, we guess, credulous editorial boards like The Oregonian's. While we don't consider any of these groups infallible, or even close, it's far more likely that fluoridation receives so much mainstream support because it does exactly what it's supposed to. It reduces the incidence of cavities."

Endorsements can be found for everything.  Endorsements are not science.


Lets keep the discussion on a scientific footing and please answer my question,

”Endorsements”?  The opinions and recommendations of such highly respected healthcare professionals, educators, Publc Health officials, and organizations.....are “endorsements”?  Well, I suppose that makes about as much sense as the rest of your comments.


Interesting that you seem not to have a problem with the constant flow of “endorsements” posted by your FAN colleague, “CaryAnne”......


So, since we’ve put Spencer’s nonsense into proper perspective, let’s do get on a “scientific footing” as I’ve been urging you to to do from the no avail.


In regard to your cap enhanced question, you must first define “EXCESS EXPOSURE”, as this could be defined in any manner.  Then, once that is established, you must provide valid scientific evidence of any such “EXCESS EXPOSURE” which may be causing a discernible problem.  My opinion, as well as probably that of most others, is that “EXCESS EXPOSURE” in the negative sense would be defined as a level just above that at which adverse effects may begin to occur.  The National Academy of Medicine has established 10 mg fluoride intake per day to be the threshold of adverse effects for daily fluoride intake.  As I personally know no one who routinely ingests that huge amount of fluoride on a daily basis, I’m not sure what it is you deem needs to be reduced.


In countries such as China and India which have massive environmental fluoride pollution, large reductions in fluoride exposure are an absolute necessity.  Among other health concerns, crippling skeletal  fluorosis is an overwhelming problem for the unfortunate residents of those areas. As such, those countries constantly struggle to reduce chronic exposure to abnormally high levels of this environmental fluoride pollution.  In the United States we have no such problems with fluoride exposure, as evidenced by the near non-existence of skeletal fluorosis,   and the lack of any valid evidence of adverse effects from the optimally fluoridated water serving nearly 75% of this country.  So, I’m really not aware as to why you are obsessed with “correcting” a non-existent problem, and don’t know how to help you with that.


Steven D. Slott, DDS








Thank you for responding to my question.   You state, "So, I’m really not aware as to why you are obsessed with “correcting” a non-existent problem, and don’t know how to help you with that."


Apparently for you, there is no amount of dental fluorosis which is of concern.  I presume if all 200,000,000+++ people in the USA had dental fluorosis even severe, that would not be a problem for you?  Or is there an upper limit acceptable to you?


You reference the National Academy of Medicine 10 mg/day of fluoride as a threshold of adverse effects.  What adverse effects did they use to make that determination?  Are you referring to the book "Health Effects of Fluoride" from 1993?  Or which one?   


I presume the 10 mg/day is for adults and what did they recommend for children and infants?  


My memory is 3 mg for women, 4 mg for men a day.  EPA has 0.06 mg/kg for an RfD or about 3 mg for a 50 kg woman.   But EPA does not include infants or those drinking the most water.   Here is their Figure 8.1 from 2010, Dose Response Analysis.  You can see they proposed 0.08 mg/kg/day, but that has not been chosen that I'm aware of. 


Note how they ignore infants, use the 90th percentile which ignores those drinking the most water, proposes to increase the RfD (EPA's "safe" dosage) and about a quarter of kids will still ingest too much even.  EPA has skewed the evidence as much in favor of fluoride as they can and still many are harmed.  


The reason I'm focused on excess fluoride exposure as considered with dental fluorosis, is the effect that much fluoride has on other tissues.  


We can't really consider risks until we know how much fluoride is excess in your opinion.

1.  Sure, Bill, the internet is a wonderful thing.  Instead of depending on your memory, and/or blurbs from “fluoridealert” all you have to do is exert a modicum amount of effort, and you can obtain a wealth of accurate, authoritative information.  Here’s a link to the NAM reference tables:


The daily upper limit for fluoride intake is 10 mg/day for children and adults above the age of 8 years.  That for infants and children 0-8 is considerably less due to the chance of occurrence of mild dental fluorosis in teeth during those teeth developing years. That such fluorosis is the only reason for this lesser upper limit is evidenced by the fact that after age 8, the teeth have developed, dental fluorosis no longer possible, and the daily upper limit jumps to 10 mg.


2.  If you have valid, peer-reviewed scientific evidence that “all 200,000,000+++ people in the USA had dental fluorosis even severe” then feel to present it any time.  Otherwise your question is moot.  


3. Your garbled opinions on the EPA...NAM...or whatever it is to which you are trying to refer, are irrelevant.


4.  If you have any valid, peer-reviewed scientific evidence of any adverse effects of fluoride intake from optimally fluoridated water in conjunction with that from all other normal daily sources of fluoride, feel free to present it any time. 


5.  You’re the one obsessed with some unquantified level of fluoride intake which you consider to be “excess fluoride exposure”, not I.  I’ve already told you that I consider “excessive fluoride exposure” to be that at which adverse effects may begin to occur.  Whatever you consider to be such a level is entirely up to you, and of no concern to me.

Fluoridation promoters argue that it does not matter that dental fluorosis increases in incidence in every city that fluoridates its people and that there are no exceptions.  Their idea is that white spots are not pathologic.  But fluorosis is properly named because it is an abnormal condition of deficient enamel layered at the fluorosed location. A surface cut which eventually heals is still labeled a pathologic trauma that requires inflammation to occur to repair. But fluorosis is permanent damage that cannot be repaired and is thus worse than simple pathology. it is a permanent abnormality. Many are affected with reduced employment oportunites because of it. And no one actually goes out and seeks for or desires it because it is an abnormality.

It is downplayed by fluoridiaotnists becuase it is the chief visible outcome of the fluoridation of people that is a recognized side effect. It is the first visible sign of fluoride poisoning. The Kumar chart is in agreeement with many other studies that show as water fluoride increases, dental fluorosis incidence increaes progressivley while dental caries are not affected outside experimental error (as in Ziegelvecker and by Teotia and others).

Second, although the NRC estimated a half life of bone fluoride at 20 years, note that it is only marrow and otehr soft tissue regions in bone that are able to have fluoride removed upon transfer to fresh clean drinking water. Fluoride removal from compact bone is not a biochemically reversible process. Fluoride is a poisonous insult to bone and has of course no function there.

"The continued increase in fluorosis rates in the U.S. indicates that additional measures need to be implemented to reduce its prevalence.” - Wiener et al. (2018)


Apologies to the senior citizens who must be disgusted by now with all the scientific vitriol since Thursday. However, since JJ brought up dental fluorosis and used a picture, I thought I'd share a picture - with excerpts from studies and citations for those of you who have noticed stains on your grand-kid's teeth, albeit more prevalent and with worse severity in Black & Hispanic populations because of a genetically determined lower tolerance to fluoride.


What has changed over the years is more and more communities are fluoridated. Dental fluorosis is a lagging indicator of overexposure from 10-12 years earlier, a predictor of increased learning disabilities during childhood, and a leading indicator of increased dental bills - for a lifetime.


DFwQuotes.jpgTo confirm the numbers, here are links to the source documents: 

2010 CDC:  
2018 31% increase in a decade:


BTW: My little daughter (white) who consumed fluoridated tap water from age one to age 3 had mild dental fluorosis on several of her teeth, diagnosed by her dentist who was positively gleeful when he saw it. I was not happy with those white stains. Since I figured out that it was the water causing rashes and stomach problems in both my children and myself, I switched to bottled water for a decade and my children's adult teeth were fine.


However, when I started using a filter about 10 years later, all sorts of other health effects emerged in my family. Sadly, I did not connect them to the water until after decades of misery.

As a senior citizen, member of AARP, and a Pediatric Dentist, you should apologize to those that may still be reading this thread.


You are misrepresenting the findings of credibly conducted science.  You are also in need of a definitive diagnosis of your "rash", as optimally fluoridated water has never been indicated as a cause of allergic dermatitis.   You should see a Board Certified Allergist.  You would be an interesting case report in their journal.


Additionally, with >3 decades of clinical private practice in pediatric dentistry, your pictures and snippets of articles does not represent in what is seen in practice.  Having seen thousands and thousands of patients over my career, from birth to mid-20's, there has never been one that required treatment for the mild to very mild dental fluorosis that is slightly higher in fluoridated communities than those which aren't.  None has EVER required dental veneers costing thousands of dollars as you state.


It is very easy to pull information from the internet and claim that it supports your perspective.  If those reading your posts are clicking on your hyperlinks, they will readily see that many do not apply to community water fluoridation as practiced in the U.S.  Additionally, many are misquoted.


Leave this to the dental and medical professionals to discuss.  Writing confusing pieces to mislead my families here is unforgivable.

Johnny Johnson,


You said, "as optimally fluoridated water has never been indicated as a cause of allergic dermatitis."  The word "never" is not a word which is used very often in science, and then it is a red flag.


Yes, there are some people who are chemically sensitive who develop a rash taking a shower or bath in fluoridated water.  I know of three.  


The cases are rather interesting.  One keeps moving when fluoridation is started in her community.


Another has a child who develops allergic dermatitis.  The teenager is in sports and they travel to different communities and stay in hotels.  Mom has made it a habit to look at her teenager's skin after a shower.   Whether or not there is a rash, mom calls the water department to confirm the hotel is or is not getting fluoridated water.  So far the results have been consistent.  No rash with no fluoridated water and a rash with floridated water.  


More common is a rash from topical use.  I do have patients who have been advised not to use fluoride toothpaste and their rashes have stopped.  


Perhaps more common than we know, but we must be careful in science when someone uses the word "never."

 Fluoride is capable of producing any number of symptoms. They include drowsiness, profound desire to sleep, dizziness, nasal congestion, sneezing, runny nose, sore throat, coughing, wheezing (asthma), chest pain, hives, and various intestinal symptoms. Most of the information concerning specific reactions to fluoride, as seen in private practice, never reach publication.” - Hobart Feldman, MD, American Board of Allergy and Immunology (1979)


How dare you! You are crossing a whole other line in offering me off the cuff medical advice and  diagnosis without a consultation that derisively dismisses me on a public forum, JJ.  


My children and I did see allergists and other MDs. Our rashes were diagnosed as eczema, psoriasis, allergic urticaria odd 'lesions' in allergic hive variety, IBS, etc. and I was advised by my doctors to only consume spring or filtered water because 'some people are sensitive to the chemicals in the water.' Also, to watch my diet in order to avoid things that set me off.  Everything set me off, because water is in everything.  15% of the population is like my family, misdiagnosed & dismisssed. 


At least a couple of those doctors were deceptive  - they knew. Their choice of language and odd treatment gave them away, although it took me a long time to figure it all out. The literature as you well know documents rashes including the odd lesions as a very distintive type of hive specific to fluoride sensitivity that a minority of women and children get in the preclinical stage of fluoride poisoning called Chizzola maculae - a symptom that the fluoridation lobby has successfully succeeded in hiding from most medical practioners.

Don't let Johnny Johnson intimidate you because you don't have a dental or medical degree.   And you are not offering off the cuff medical advice.  


If we are going to start that kind of intimidation, then we could charge all the dentists and physicians talking about fluoride with malpractice because none of us are licensed in every state where people are reading these posts.


Johnny is only trying to make you feel inferior.  A bully, such as Trump, uses intimidation and public threats and intimidation.  He especially likes to pick on those with less power, such as children, especially immigrant children because they can't fight back.


Your posts, facts, and references are most reasonable.  I think we can all agree that a Cochrane review of RTC studies has more weight, but because fluoridationists refuse to do those studies, we have to use trials and reports with lower confidence.  


You have better judgment when evaluating the evidence than some on this forum blinded by bias.

Yes, all seniors need to do is observe how much “stain” they have noted on their grandkids’ teeth.  In doing so, they will note very little discernible discoloration which can in any manner, be attributable to fluoride exposure.  Why?  Because dental fluorosis is not a problem in regard to optimally fluoridated water, and is certainly not a problem that antifluoridationists have attempted to pump it into being.  The only dental fluorisis considered to be an adverse effect is severe.  This level of dental fluorosis is rare in the US, and does not occur in communities with a water fluoride content less than 2.0 ppm.  Water is fluoridated at 0.7 ppm, one third that level.  


Steven D. Slott, DDS



You asked for references for the CDC Figure 1.  Note the CDC has 5 references for their data.


And you said only "severe" dental fluorosis is an adverse affect.  And if a patient comes in and wants treatment for moderate or mild DF, am I supposed to say they have a monosymptomatic hypochdriacal psycosis and send them out the door?  


Harm is in the eye of the beholder.  If I scratch your car, the car will run just fine and I'm sure you would not call that severe damage, so it is only cosmetic and does not need to be repaired, right?   Wrong.  If I scratched your car, it is harm.
