I have had a burning sensation around my lower last molar and tongue on the right side of my mouth for several weeks and it seems to have affected my throat. When I swallow food, it seems to be scratchy. The molar has a gold crown except the top surface which the dentist opened up to do the root canal later and was refilled with some kind of dark filling. All these were done a number of years ago. I was at the dentist for check up and Xray less than 6 months ago and was told that everything was OK. This is not a major pain but certainly extremely annoying. Also, prior to that burning sensation I had little round white bumps on that side of my tongue for a couple of days. I've been on strong antibiotics for another condition, thought it would kill all bacteria. Can it be some sort of virus? Please help! Thanks so much!
