question: I have been experiencing tongue discomfort. I can eat and swallow with no problems.  However, my gums have been sore and there has been a burning sensation in my cheeks and there is a white (pimple) like bump on the left side of my tongue,  My dentist and an MD have done visual inspections and both have said that everything looks fine (no discoloration or lesions).  However, I have noticed a small bump in the roof of my mouth.  Could I have an infection?  There is no foul taste in my mouth.  I've been cleaning with warm salt water.
