Well all they did is say they couldn't find anything! They touched some instrument to that tooth and the ones surrounding it saying it had something to do with a root canal- that they most definitely di NOT do!- and I raised my hand both times he touched my teeth to say that it hurt. He said this was normal. So he gave me a flouride treatment for free and I left. No payment necessary! Now I feel like an idiot for going in. He said my prescription toothpaste should take care of sensitivity of all my teeth.
