Blister below gum

[~max~]

Hi! I have what looks like a small white blister under my gum (about a milimeter in size), just below my bottom from teeth, where the gum meets the skin of the lip. I haven't hurt the area, and haven't made any change in my diet. What can this be? It is quite sore, a bit like when you bite your cheek. How can make it go? Thanks!

Could it be a mouth ulcer? Anyway, pop down to your local Chemist who will be able to recommend something to put on it.

Hi max there are a number of possibilities for the lesion you describe, some of the common ones are:
- ulcer (of which there are various types)
- a 'sinus' from an area of infection associated with your gums and/or teeth
- a burn
- an allergic reaction etc

If its an ulcer it should normally heal within three weeks if it persists beyond this time you shoud attend a dentist.

Thanks! I googled mouth ulcer and it seems to be that, although a lot smaller than the pics I saw. Will go to the pharmacy tomorrow and ask them.
