I had a badly infected upper molar which had caused me a very horrible pain. When I went to the dentist, he referred me to an endodontist who immediately performed a root canal to let the pain subside. He gave me strong antibiotics and pain medicines after the procedure. It was fine for 9 months but then it started to bother me again. My are swollen and hurt really bad. Could it be infected again? The said before that he's not sure if the root canal can save the tooth because it was in a pretty bad shape but he suggested a re-treatment in case I still have problems. If it is infected again should I just get it pulled?
Another problem I have is the tooth below the canaled molar. I started to have throbbing pain from this tooth. The gum around it is very sore. Is it possible that the infection has spread to this tooth also and it is now showing symptoms? The teeth beside the infected molar look fine. What do you think? Thanks a lot!
