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.

There is a legal initiative in Peel, Ontario (pop 1.3m) to remove fluoride from the water supply based on the principle of gross disproportionality, i.e. marginal benefit does not justify great risk of harm.

AARP - STAND UP on our behalf! 




You call me a liar because you are acting like a bully.  (You say, "Figment of my imagination").  


Just because you did not spend time searching and reading the articles on PubMed, does not give you the right to call me a liar.  How rude can you be.  Simply search under the words fluoride induced cancer and read the articles.  It will take you a few days, but you will learn a great deal.  Do not insult me with your lazy sloppy failure to read the literature.


You fail to consider dosage or answer any of my questions on excess exposure (that I can find previously in our discussions or here).  You avoid the foundation of fluoride pharmacology. . . dosage.  


Fluoridation is a house of cards, built on failure to consider dosage.


Yet you want me to be your research boy and get you research and spoon feed you. . . maybe IV, or should I put the research in your water so you have no choice but to ingest?    If I gave you the reference, I doubt you would even read it.


So how do you think the pharmaceutical companies cause cancer in animals? Several methods, including injecting the animals with the cancer cells.  And administering fluoride, other toxins, etc.


On another note, I found this research of interest:


Toxicology Ind Health


2009 Feb;25  Fluoride-induced thyroid dysfunction in rats: roles of dietary protein and calcium level.    Wang et al. Abstract

"To assess the roles of dietary protein (Pr) and calcium (Ca) level associated with excessive fluoride (F) intake and the impact of dietary Pr, Ca, and F on thyroid function. . . Thus, excessive F administration induces thyroid dysfunction in rats; dietary Pr and Ca level play key roles in F-induced thyroid dysfunction."


Diet is a factor, so is fluoride with tyroid dysfunction.  So what is the dosage which causes thyroid dysfunction, cancer, brain damage, etc.?????? With synergistic toxins, host sensitivity, etc?   


It is all about dosage and host.  


But then, I doubt you will read the article or articles and if you do, I doubt you will understand what you have just read.  


Don't call me a liar.  A professional is never a bully.


Now. . . think dosage when you read anything about fluoride.  


And concentration is not dosage.


Bill Osmunson DDS MPH


Bill, I did not call you a liar but having done my own search I do not believe you had found a paper you claimed to. A simple way for you to change my mind - provide the citation I asked for.

I have no further interest in hunting down what could be a fictional claim.

Really weird for you to attack me for your inactivity and then to go an provide a citation for something irrelevant to the discussion.

But as I said, you are not a reliable discussion partner. Blocking people becuase they show where you are wrong is hardly good faith discussion.

"Carrie Anne,"  your quote:  


"Question 1: Why did a New Zealand blogger infamous for his posts supporting fluoridation & denigrating opponents both on his blog and on letters to the editor across the English speaking world suddenly join the AARP - American Academy of Retired Persons which is "dedicated to empowering Americans 50 and older to choose how they live as they age" with a barrage of insults directed at the senior citizen Americans on the AARP forum?

  • Answer: He was recruited by a small but organized team of fluoridationists."


Response:  Since I am almost the only "fluoridationist" commenting on this website at the moment, it's a reasonable assumption that you are referring to me.  I can assure you, "Carrie Anne," that I did not "recruit" KenP.  I know him from his blog and I can honestly say that I disagree with him about almost everything, except perhaps this issue.  And why would that be odd?  Most people in the English speaking world support CWF. 


Your little fringe anti-fluoride group is so small that only 4000 signatures were collected Worldwide on the Fluoride Action Network's "Opposition to Fluoridation Statement."  That represents a whopping 0.036% of all health care and other professionals who believe what you believe.   The fact that KenP and I agree on this issue is completely in line with the odds.


Who recruited KenP?  I don't know . . but I can say that they have this really cool thing called "Google Search."  It's pretty slick.  And since KenP does take an interest in this subject, it is reasonable to assume that he might be in on that neat internet trick "Google Search."


Now I'm going to do what you do.  But this has absolutely nothing to do with you.

"Carrie Anne," 


Ken P, that retired chemist living in New Zealand, invited you for a scientific exchange on his blog page, "Open Parachute."  The advantage of such an exchange on that forum is that comments won't be lost or buried by other people commenting who are in fact attempting to bury them.  You wouldn't know anything about that though, would you.  


So I am confused by your response.  It is rather vague.  Is that a "Yes," you would be delighted to engage in this proposed discourse, or is that a "No," you would rather have your out-of-context citations remain unchallenged, . . . and if challenged, have the corrections buried?

It's not my spelling. It's using a cell phone while on the run.The spelling has now been corrected.

I've read vast literature and advertisements on the "benefits" of fluoride and all of them are nothing rigorous.The full study for example that demonstrated the bias in the original Dean study was by Ziegelbecker who used all the available data and proved that the Dean conclusion was based on a limited data set. There is no benefit to teeth from fluoride water even to 6 ppm.

The original forced human experiments in Grand Rapids and Newburg were not even controleld for calcium content of the water with the untreated cigties used as "controls" and would never have been approved or published under peer review in today's scientific world. For a review you might wish to consult the textbooks by the dentist statistician Phillip Sutton, Errors and  Omissions in Fluoridation Trials (the Great Fraud Fluoridation) . If you want to cfhallenge the lack of effect on dental caries, then address these detailed thorough references please. 

Good luck

Richard Sauerheber, Ph.D.

Richard, I would pat you on the back but your hand is in the way. Besides Iid do seriously question that you have "read vast literature" becuase you seem to rely on a few bad discredited studies.

If you could drag yourself away from the ideologically approved (and therefore unscientific) reading you would find that again and again scientific studies have confikrmed the efficacy of community water fluodiation. Reviews of the subject also confirm this.

There is no trouble finding citations for such studies and reviews, of course. You could start with the recent Cochrane review (which has been dishonestly and disingenuously condemned by anti-fluoride activists) which confirmed:

“Data suggest that the introduction of water fluoridation resulted in a 35% reduction in decayed, missing or filled baby teeth and a 26% reduction in decayed, missing or filled permanent teeth. It also increased the percentage of children with no decay by 15%. These results indicate that water fluoridation is effective at reducing levels of tooth decay in both children’s baby and permanent teeth.”

Of course, studies vary in quality - nothing unusual there. But can you find a single study of higher quality than those reviewed which show CWF is not effective? If so - please provide the citation and we can investigate what it actually says.

I really love to seriously assess scientific papers for their strengths and weaknesses.

No one i know has such data because everyone eats and,drinks completely differently than soneone else. But i dont focus on the brief interval during which one is,eating. I am talking about the data from teotia and from ziegelbecker and from yiamouyannis and the most conclusive of all, the perfectly controlled mammalian stidies, all proving beyond doubt that fluoridated water consumption does not affect dental caries even up to concentrations in water as high ae 6 ppm in humans. Thats that.

Richard Sauerheber, Ph.D.

Richard, your spelling is deteriorating.

You, of course, have backed away with vague comments like "brief interval." But, in fact, that interval is about 1 hr. so that eating and drinking throughout the day helps to maintain a protective concentration of F in saliva.

You have to be living a hermit life scientifically to claim there is no evidence that fluoride plays a protective role or to ignore the clear differences in tooth decay between fluoridated and unfluoridated populations in simple regional and ethnic areas of a country.

Making such a claim just indicates how strongly ideology prevents you from seeing the bleeding obvious.

0 Kudos



Am I to understand you are suggesting that if a person eats or drinks about every hour, the fluoride in the beverage and food protects against tooth decay?


Would you provide references?


What research do you rely on to show, as you say, "a clear differences in tooth decay between fluoridated and unfluoridated populations in simple regional and ethnic areas of a country." 


As a dentist, I have attributed fluoride as beneficial because that is what I was taught in school.  However, a simple comparison between states, or counties, or provinces of Canada when they are ranked on their whole population fluoridated, does not show a clear benefit from fluoridation.  Indeed, there is a very clear difference in caries based on socioeconomics, but not fluoridation.  


And the studies I have seen show very little diffeerence and have serious confounding issues which were not considered.  


Again, fluoride might have a benefit but detecting any benefit on a population basis is simply not clear.  Perhaps due to the excess fluoride from other sources, but benefit from fluoridation is not based on good science.  


I took CDC and HHS data and ranked the 50 states on the percentage of their whole population fluoridated and percentage of each state reporting the percentage of "good or excellent" teeth.   You can see by the dark blue line below that one state had almost no fluoridation and one had almost everyone.   


You can see the pink ranking of tooth decay for the more wealthy is about 82% and the poor, although not as consistent, is about 55%.   Clearly the wealthy report better oral health.


Consider the effect of fluoridation.  We do not see any common cause between fluoridation and good teeth.


The evidence of a public health benefit must be measured in the public at large.  


Thank you for your consideration.

Bill, I feel the need to warn you that I am the Ken who you blocked on social media in an attempt to close down a discussion. I will understand if you now retreat from this one.

However, it is surely hypocritical to block me on social media and then expect to enter into a discussion with me here.

The question of persistence of calcium, phosphate and fluoride transferred to saliva and plaque from food was discussed in my exchange with Paul Connett. I suggest you refer to that for citations (I am away from home on holiday at the moment so do not feel like doing that search for you - ex=specially with your blocking behaviour.)

As for studies showing the efficacy of CWF, you could start with the Cochrane review. If you argue about quality, etc.. then I challenge you to provide a citation of higher quality showing no benefits - particular a replicated, blinded controlled study. The ball is in your court.

No, the pathetic graphs Connett's crowd produce comparing changes in tooth decay prevalence in various countries from WHO data does not qualify as a study, let alone a reputable one. There is nothing new in your observation of socioeconomic effects. Nor is there anything new in ethnic effects showing up in health statistics. 

I have often shown the New Zealand data shows a clear difference when ethnic effects are removed (something the anti-fluoride activists locally dishonestly refuse to do. And the NZ Oral Health Survey used populations selected to balance out socioeconomic and ethnic differences and showed a clear difference.

I honestly cannit get my head around anyone who pretends to have any authority on this subject making the claims you do.

Many dentists believe and state that lack of fluoride increases caries incidence. Like the yiamouyiannis claim on Aids this claim is also false r. Caries,are,caused by bacterial acids subsequent to growth from sugary foods left on teeth.

But dentists can be wrong about this while still being correct about other things they ro.

Ditto john yiamouyianns.

Ken P.,

Still referring to  C-104 to C-111 of

Your comment, “Pyromorphite is usually the Cl compound Pb5(PO4)3Cl. Yes, isomorphous substitution occurs but what surprises me is that there are no analytical data given in this section for F. See table C27, page C106. This makes me suspect the pyromorphite identified by XRD is not the fluoride analogue but more likey a Cl, phosphate, OH analogue.

The description of pyromorphite as the fluoride analogue in Table C26 appears to be a mistake. If the authors seriously suggested it was a fluoride analogue they would have provided analytical data for F, not Cl. I also note that the report describes fluoropyromorphite as "rare" and the Chloro and Hydroxy analogues as "common."

end your comment

Yes I noticed no analytical data for F on page C106, unfortunate but not conclusive.  How can you speculate what the authors intended or not? This does not mean the data clearly labeled as fluoropromorphite is a ‘Mistake”.  Figure C.95 clearly labels dominant peaks of pyromorphite, Pm =fluoropyromorphite.
Table C26 has at the top of the column “Pb5F(PO4)3” and when listing various forms of pyromorphite on page C-107, why X=F is mentioned first before Cl or OH? Not Alphabetical? By most abundant?


Where is the statement you said is in the report, “fluoropyromorphite as "rare" and the Chloro and Hydroxy analogues as "common." ” ?


Unless you get the authors' of this report to correct their "mistakes", I stand by my statement the scales were mainly compounds of fluoride.


Sorry skanen144, I missed this comment before. I have now answered your question about the location of the comment about rarity.

I am not speculating about what the authors intended - just drawing conclusions from the information they provided. The XRD pattern identifies the crystalline species present but not the composition. It especially would not identify the relative amounts of OH, Cl and F in the structure (although a fine structure analysis might go part way). The Chloro form is most common but one would expect a reasonable amount of OH in the real-life pyromorphite - and some F if any is present in solution.

But it would be completely unreasonable to attribute the XRD peak to just one pure end member analogue, and even more unreasonable to attribute it to a pure end member F analogue.

You are welcome to "stand by" your statement - no skin off my nose. I am just saying it is not warranted by the evidence. And I really have no interest in chasing up the authors - where would I have time to live if I followed up every vague statement in reports.

I am not sure what the whole point if this pointing to pyromorphite scales after phosphate treatment is, anyway.

Bronze Conversationalist

the point is that fluoridation is not the operation that somehow magically only decreases teeth caries while having no effect whatsoever on people or plumbing parts or anyting else, like fluoridationists claim. One water district official argued that the quality of rhe watrer is totally intact and unaffected by fluoride. I merely said if that is the case then why bother to add it?  He quit his job within a week.

These reports are whole country averages in fluoridated and nonfluoridated regions and cannot show the effect of fluoride in impairing death rate declines. Yiamouyiannis used well controlled city cases.

For,example look at population growth in the whole world from the 20th century and you could conclude there ,was never a world war  because of the ever increasing population. But if you just look at countries that were involved in the war the populatuon showed an overaall huge dip because there indeed was a WWII with massive deaths.

The,examples,here are all factual but the notion that fluoridation does not affect cancer survival is not proven by the presented data. That suggests improved detrction and treatment methods are helping to bring rates,down.

The yiamouyiannis  data does show the impairment. Whole country averages mask the effect. And of course fluoridationists use that to denigrate the yiamouyannis study.

John was giving an early opinion on AIDS that was incorrect. What expert is never wrong?  Being wrong on something else does  not negate the correctness of an actusl study done properly.

Dr. Richard,


Still trying to fear-monger using a pamphlet whose author (the guy who said HIV doesn't lead to Aids) was discredited by reputable organizations in the last century. 


Your quote:   "These reports are whole country averages in fluoridated and nonfluoridated regions and cannot show the effect of fluoride in impairing death rate declines. Yiamouyiannis used well controlled city cases."


Of Yiamouyiannis' work, the National Cancer Institute said, "The National Cancer Institute, whose figures are cited in the Federation report, in March noted errors, omissions, and statistical distortions in the Federation report and stated that "Results of this analysis fail to support any suspicion of hazard associated with fluoridation."   Please, take a look.   -  Your argument is with the National Cancer Institute, not with me.


I'm confused by this quote from you --  "the notion that fluoridation does not affect cancer survival is not proven by the presented data. That suggests improved detrction and treatment methods are helping to bring rates,down."

Odd you would say that, since you are the one who brought up cancer mortality rates in the first place, (Timestamp ‎02-18-2019 01:28 PM)  . . and you're a really smart guy, . . so if "cancer survival" is irrelevant because of improved treatment, as you are saying now when presented with valid current data, why would you even bring it up in the first place?  

Bronze Conversationalist

One thing you said I agree with, that is you are totally confused about my quote. 

I did not say that cancer survival was irrelevant. It must be nice to change peoples' words to have the luxury of criticizing and demeaning them.

To help your confusion:  Yiamouyiannis carefully examined pre and post fluoridation data on cancer mortiality in cities in the U.S. In all cases, the decline in cancer mortality incidence that occurred in all cities was slowed by fluoridation. So, again, the idea that others have somehow proven that fluoridation does not impair the decline in cancer mortality is absurd. The cancer statistics you provided are for the whole country and do not separate fluoridated from non fluoridated people. So of course cancer overall incidence declines will be found due to improved detection and treatment. 

But fluoridation interferes with one's ablity to fight cancer because fluoride is a toxic foreign substance in man and the rate of decline of cancer mortality incidence is not as great in fluoridated cities. This has all been thoroughly vetted in several court trials by epidemiologist experts. You can choose to believe who you want because of your desires. i choose to stick with the actual data from observations that were well done to address the specific question. 

Please stop spreading your confusion to everyone else.

And I don't scaremonger. If fluoridated water is all you have to drink in the middle of the desert, then drink it.  But if you expect me to hide the truth about its long term ingestion you are barking up the wrong tree. i don't lie, to my family, friends, or anyone else.

Richard, still at it I see.  


Your quote:  "I did not say that cancer survival was irrelevant. It must be nice to change peoples' words to have the luxury of criticizing and demeaning them."


Response:  Before you play the victim here, slow down and take a look at what you said:  "the notion that fluoridation does not affect cancer survival is not proven by the presented data. That suggests improved detrction and treatment methods are helping to bring rates,down."

My response to that was:  "so if "cancer survival" is irrelevant because of improved treatment, as you are saying . . "


As you seem to have limited capacity, yes, you said  current data which shows cancer rates are declining (that would be cancer survival) is irrelevant to the fact that the practice of water fluoridation is increasing.  You said this is because of improved treatment methods . . . which begged the question, why did you bring it up in the first place.


It must be nice to live in a world in which you can absorb half a thought, take it out of context, and then pretend that you are some sort of victim.

Bronze Conversationalist

What  if cancer mortality incidence dropped from 7 million to 4  million per year due to improved detection/treatment methods somewhere. If fluoridation were nonexistent then the rate could have went from 7 to 3 million. But fluoridation is present and the rate of decline is not as great because of it (Yiammouyianas finding).

Your claim that fluoridation is irrelevant in affecting mortality incidence is not proven by the data you presented. No one looked at fluoridated vs non fluoridated regions so the effect would not be recognized. You cant see what you don't look for. A snake under a rock is never seen unless you roll over the rock.

Why is this so difficult for you?


Richard Sauerheber, Ph.D.

Yes and in the real world in a city with 1 ppm fluoride water, in the 21st century, ,eating and drinking modern foods  and beverages , the average fluoride level in saliva is 0.016 ppm. Do you want me to change the number the NRC 2006 Report published??

Richard Sauerheber, Ph.D.

Richard, I think I have done enough for the average intelligent person to understand. For somene to insit of thinking freshly excreted saliva before eating and drinking is relevant to someone eating food and drinking beverages requires a level of intellectual stubbornness which makes rational discussion impossible.

But you are welcome to provide the citations for measurement of saliva chemical concentrations for someone actively drinking and eating if you can.

Bronze Conversationalist

Fluoride from saliva on fluoridated cities bathes teeth 24 jours a day, sll without any use. Fluoride from foods and beverages are also not near 500  ppm and ate not present on teeth 24 hours a day like saliva.

 Water fluoride is 0.7 ppm and also resides on teeth during swallowing and soon replaced with saliva.. So what? I try to eat foods devoid of fluoride to protect bone accumulation of fluoride which far more difficult in a forced fluoridated region. 

Richard Sauerheber, Ph.D.

Richard, please stop squirming in an attempt to avoid the established science. Whether or not the slightly elevated F content of freshly excreted saliva has an influence or not is not at issue.

We are discussing the real world saliva which during the day contains fluoride, phosphate and calcium directly obtained from food and beverage. And also from toothpaste use and CaF2 reserves in the oral cavity. This has absolutely nothing to do with freshly excreted saliva - please stop trying to confuse the issue.

Whether or not you attempt to avoid F in food is also irrelevant. The established fact remains that in communities with water fluoridation tooth decay is reduced and the science indicates that with existing teeth this arises from the surface reactions involving phosphate, calcium and fluoride in saliva.

”Fluoridation is against all modern principles of pharmacology.” - Dr. Arvid Carlsson, neuropharmacologist. 2000 Nobel Laureate in Medicine and official scientific advisor to the Swedish Government (1923-2018)


What we are talking about is the immorality of adding a poison to municipal water supplies based on a 1940s assumption that an arbitrarily determined concentration of it is not harmful when consumed in any dose by everyone from pregnant women to senior citizens with kidney disease. 


What we are talking about is the arrogance of fluoridationists who deny science and denigrate opponents in an attempt to bully professionals, politicians & public into compliance. 


What we are talking about is the stupidity of assuming our attempts to pH balance water systems and our fluoridation mechanisms don't fail resulting in permanent damage to people, plpes and planet. 


Fluoridation is medically contraindicated or ill advised for millions, including pregnant women, bottle fed babies and senior citizens.

PREGNANT WOMEN: Pregnant Canadian women drinking 'optimally' fluoridated water had twice the fluoride exposure per individual testing as compared to pregnant women in non-fluoridated Canadian communities - and consistent with the range in the Mexican women whose children had up to 6 points lowered IQ based on prenatal exposure to fluoride (from salt). Excluded those with health conditions such as kidney disease as well as considered confounding factors such as tea consumption.

OVERDOSED BABIES: Over one third of babies (37%) in fluoridated American communities consume amounts of fluoride in excess of the upper limits of fluoride considered safe per government regulations. Even 4% of babies in non-fluoridated communities are overdosed on fluoride due to consumption of products made with fluoridated water. At the very least, this puts these children at high risk for developing dental fluorosis, which is associated with increased incidence of learning disabilities, broken bones and kidney disease.

LEARNING DISABILITIES: Over 200 children were individually tested. Study found attention deficit disorder apparently caused by their prenatal exposure to fluoride specific to dose. This is the 3rd report out of the NIH sponsored 12 year study that seems to have been designed with the intention of showing no ill effect, but instead has three times confirmed low dose prenatal exposure to fluoride consistent with exposure in 'optimally' fluoridated communities causes subtle but permanent brain damage for many consumers. Excluded those with history of mental illness or conditions such as diabetes and renal disease.

IQ: Validated that IQs of children are lowered on a dose-response trend line correlated with the amount of fluoride exposure as measured via urine tests of their mothers during pregnancy and individualized IQ tests of offspring. In the range consistent with doses in optimally fluoridated communities, there was up to a 6 point difference in IQ. This NIH sponsored 12 year longitudinal study excluded diabetics as well as those with kidney disease or pregnancy complications and allowed for many confounders.

CarryAnne you express concern about people who "who deny science and denigrate opponents in an attempt to bully professionals, politicians & politics into compliance" And then you post a long list of claims related to scientific studies which would be interesting to discuss and discuss in a respectful way.


I am prepared to offer you full right of reply in an ongoing exchange of scientific opinion on all the claims you make here (they are far too extensive to discuss rationally in this forum). This could be done by alternating articles on my blog Open Parachute.


Paul Connett and I carried out such a good faith scientific exchange 5 years ago and covered these sort of claims in detail. it was well received by readers and is available as a pdf to download - Connett & Perrott (2014) The Fluoride Debate -

Would you agree to a similar exchange with me? I think this would overcome charges of science denial, denigration and bullying. And the formal scientific nature of the exchange will encourage it to be respectful.

Please let me know here if you are willing to participate in such a scientific exchange - and if so, some way of contacting you to make the arrangements.
