I was wondering if anyone would know why I'm having horrible pain in the back right bottom of my mouth. Everyone knows that behind the molars, in the jaw, there's a strip of gum. Normally, mine are flat and don't bother me, but that's not the case right now. The left gum-bottom is flat and normal, but the right gum-bottom is now a huge lump that's so large that I can't clamp my jaws together. My mother thinks that they're my wisdom teeth, but doesn't 15 seem to young to have them come in? I thought wisdom teeth only arrived in a person's late twenties. In either case, what do you guys think? Has anyone ever felt this, or am I just weird?
