I went to the new dentist and asked all the questions ect. As she was probing my teeth I explained one tooth #4 it will zap me if she touches it with the metal tool, sure enough the first tooth she touched was the one (keeps me out of the dentist chair, keeps me from getting cleanings, caused me anxiety( a huge zap, made my eyes water. Because she couldnt check it, I have to go back for a "debrivement"? not a scaling, unsure what is even is, she said I will have to be numbed on the right upper side and when numb she will check out that tooth, she applied flouride gel on all the teeth and prescribed flouride toothpaste to keep cavities away, 4 teeth are starting to get cavities. The last few days when I have eaten I am getting the zap on that tooth, one of those zaps has been with eggs galvanic tooth? I will say maybe the first hour after the flouride my teeth felt normal first time in months, then it wore off. I also asked her about the few teeth with cracks and she called them crazies. What do you know about this galvanic shock? I swear I am ready to get this tooth extracted. Thank you very much.....
