What causes bump on tongue?
Patient: Hi - I felt with my tongue that on the inside of the mouth near  the lower corners of the lower part of my mouth there are a small bump on each side.  Problem is on the left side the bump seems to be a little enlarged even though there is no pain.  Could i have been softly biting that bump with my teeth while asleep? Doctor: Hello and thank you for your question.Bumps in the mouth can be from infection, trauma or cancer. If these bumps are enlarging then see a doctor or dentist, especially if you use any form of tobacco. If you think it is just trauma from biting it in your sleep then it should go away in a week or so. If not see a doctor or dentist.Regards
