Hi, I was wondering if anyone could give me some information.

Two weeks ago I chewed on my cheeks during my sleep. In the morning, I had sores on the insides of both cheeks. One of them healed that same day, the other is still there. It is quite small and white in colour.

Is there any chance this could be a cancer? I have never smoked, I am 20, and I drink in moderation. I am seeing a doctor about it just in case. If it could be a cancer, does anyone know the probability?

I also seem to have a small indentation or hole in my tonsil on the same side of the mouth. Could this be related?
