Hello, Dorothy, I am so very sorry you're having so much trouble getting dental care! You are very upset right now; is there something you can do or someone you can call who will help you feel a little bit better? I think there must be a dentist near you that would accept your Medicare Advantage Plan coverage at least in part. And most dentists have payment plans for whatever isn't covered. Tooth pain is terrible!
Please know that you can go to an emergency room if you are feeling like you might harm yourself. And the staff there would help you with 'follow up', finding care for both your mind/spirit and your teeth!
I will keep thinking on your predicament, and write some more. If you have the strength and focus, tell us more. What have you tried?
But first reach out to someone you trust ...
Jane
