Hello, as of a few weeks now (I noticed it about that long), I have two dark spots on the insides of the cheek. One is about the size of a dime, and the other is smaller, but I don't understand what can possibly be the cause. I don't smoke, or chew tobacco, and I do have a wisdom tooth that strategically placed itself crookedly on the right side (where the larger spot is). Besides the occasional inadvertent cheek-chewing, nothing else was wrong with my mouth. Oh, and the spots are painless.
Anyone has had this problem?
