A member asked:
Dentist said canker sore, but it won't go away been longer then 2 weeks. been using a med paste on it for about a week, what else could it be?
A doctor has provided 1 answer
Canker sore: Canker sores heal spontaneously in 7-10 days. Return to your dentist, or see an oral surgeon, and have it reevaluated. Any sore that does not heal in 10 days needs to be examined, and possibly biopsied.
