In May I had pain in my lower left jaw and teeth-mostly in the middle to left front. I went to my dentist who isolated the tooth in question(#24?)by tapping on the teeth. After an xray showed no sign of an abcess, she proceded to do a root canal which went fine. I saw the xray and it looked identical to the next tooth in which I had had a root canal about 10 years earlier. She managed to complete the process in 1 sitting. It was sensitive for a few days- which I expected. I went out of town and realized that this tooth was still very sensitive-not to cold or hot but when I touched it on the top or sides and it "sings".I went back twice and both times the xrays looked better than before. She filed it down as she thought that my grinding and clenching was disturbing it so I got a mouth guard-this didn't seem to help.Thus she felt it could be the dental ligament? and it takes quite a while to heal. It's almost September and I don't feel any relief. Please help!
Thank you for your time!
