Is bad odor from the mouth caused by infection or something else?

Q. I had a root canal about 4 years ago. Starting about 6 months ago I couldn’t eat on that side of my mouth due to pain when biting down. I also have a small knot next to the tooth. In the past two weeks there is a very noxious odor coming from the tooth. Is this caused by an infection or something else? I’m just a little unsure where to go from here.

A. It maybe that the root canal is failing. If that is the case your dentist will need to find the reason and then decide if the problem can be succesfully treated and then the tooth restored. Extraction, retreatment endodontics ( maybe referral to specialist ) replacement of the tooth with a bridge, denture or implant might be options.
