I suffered from a tooth pain, went to the dentist and changed the filling of the tooth. I was still in pain. I did the root canal treatment for the first time and it was clean. waited a few weeks the pain didn't go. I did the redo of the root canal treatment. I was still in pain. had an x-ray for the same tooth everything is clean. I still have the same pain.Went to the neurologist gave me some kinds of medicines didn't work. I'm still in pain. This has been on since three years until currently.
