Canker : Canker sores (reccurent aphthous ulcers) last for 10 to 14 days, then disappear. They come back from time to time. If your lesion is there longer than two weeks, you need to have it evaluated by an oral surgeon to determine what it is. Regardless of insurance you need to be evaluated, especially since you used smokeless tobacco. The exam may save your face and your life. You cannot put a price on that.

Probably canker sore: White spot in the cheek area is usually a canker sore brought about by stress or cheek biting.
