Dentistry/Sore in mouth


I have a sore in the back of my mouth behind my wisdom teeth where my mouth connects. its white in color with maybe a tad of yellow in it. I was wondering what this is.

Sores can be caused by a number of things. Viruses, bacteria, localized trauma, and growths(less likely). In general if a sore doesn't go away in about two weeks it should be checked out  and possibly biopsied. Fortunately most sores resolve them selves. In the meantime you might rinse with warm saline solution made by placing table salt in in a cup of warm water.

As I have indicated, if it doesn't resolve within the two week period, it should be looked at by a dentist or an oral surgeon and if then a biopsy should be done.
