I had a whole in my back tooth. The dentist that I went to, was a first time thing. he did some things to my motuh, that I nver authorized him to do, and is actually demanding I pay him for it. Anyhow, one of the things he did, was put a big filling over the tooth that I had a hole in, it was fine after a few moths, then i began having sever pain. I took all kind of pain killers, and everntually it went away, before I had the chance to get it pulled. Well, the tooth no longer bother me, and almost a year later, I have a huge knot under that tooth. I went to the dentist, because I was a bit scared, the dentist gave me medication, and told me I would eventually have to get this tooth pulled, or get a root canal. WEll my hard headed behind didn't do either, I now have a bump over top of the knot, it is filled with pus, and the more I bust it, the more it comes back. Has anyone ever had this problem, and if so, WHAT THE HELL IS THIS LUMP, and is it as severe as I think it is.
More than likely it is a mucocoele which is benign. The small mucous ducts get clogged and the gland fills up with the fluid. It it is always safe to get it checked out by an oral surgeon. I do not think it is related to your cheek biting.
