Small pimple like bumps in mouth usually on inside of lips and sides of the uvula not painful just annoying I "pop" them they go away?

Inclusion cysts. These come and go, they're not oathologic, just annoying. Don't worry ! .
See dentist. It is not a good idea to pop the "pimples" in your mouth and I wonder how one can even manipulate the uvula without gagging. Do ask your dentist to check them out.
