question: I have a white spot on my gums it's right under my bottom teeth and it hurts pretty badly sometimes. Mostly at night and better in the morning. It sort of looks like it's the opposite of a bump like a small crater or something. There is also a tiny white dot next to it. This is making the gums on my lower lip hurt very badly as well. I know I should go to a dentist but I want to know if it's a huge problem yet. Some additional info that might help is that I have not had my wisdom teeth out, in fact I'm not even sure if they came in yet (I'm 21 though) and where those teeth should be was bothering me a couple weeks ago.
