Has anyone had a root canal recently, and how long did it take? I have a tooth that has a temporary filling in it now, and the dentist said that it doesn't obviously need a root canal. There is one spot on the xray that they cant tell much on that is a little suspicious. I had a wisdom tooth removed last month right next to this tooth and now this tooth is sensitive. I also had a lesion on my gum a few days ago that hurt quite a lot. Saw the dentist and he wasn't sure if it was the tooth in question getting bad or just the sore on the gum. Anyway, the sore is better but the gum around the tooth still hurts and is sore. I'm hoping that the tooth is just reacting to everything, but I'm worried that it will need a root canal. I take xanax to help me but I'm still worried. Any thoughts will be welcome.
