I have a spot on the dorsal surface of my tongue, sort of near the back and off to the side, where occasionally I will develop a red patch that looks smoother than the rest of my tongue. It goes away and recurs every few weeks or so, and it's always the same shape/size and always in the same spot.
What are the possible causes of this, and do I need to see a specialist? Thanks.
It sounds like it could be geographic tongue. It is a variation of normal that occcurs in a small percentage of the population. It is a benign condition and does not require treatment. Without seeing the area, I can not give a definitive diagnosis, therefore it would be wise to have it looked at by a dentist or an oral surgeon.
