I have a tooth that has broken off. I had a root canal about 5 years ago. Now where the tooth is broken, there is extra gum growing in. It really is bothersome and sore. I sometimes want to cut it off, cause it’s like hanging and moveable. I am planning to visit a dentist in Edmonton ( rootsonwhytedental.com/meet... ) very soon but before that, I thought to ask here if anyone knows what this is? So that is would be easy for me to explain to the dentist about my problem.
