A member asked:
I had a blister (i think) on the inside of my upper back left molar against my gums. it eventually popped (rather gross). infection or cavity maybe?

Cannot say: without an exam, I can only give general information, but... "gross" implies a need for evaluation and antibiotics. If cavity, then it is going into an abcess and spreading. if gum infection, will resolve better and with less risk of complications with same.

BLISTER: you should see your dentist as soon as you can as this sounds like an infection of the nerve (the nerve in the tooth may have died leading to the infection). It is easily solved with a root canal and crown. See your dentist soon before the blister returns.
