I have a couple. First of all, I seem to have a hole in the side of one of my teeth. It is on top, the one furthest to the back on the left side, and the hole is right up by the gum. If I reach back and touch it with anything, it hurts, so I think the nerve may be exposed or something. Is this a cavity or not? If so, would it hurt more than a normal cavity to have filled? Is there anything that I myself can do for it?
Okay, as for my second problem. On my right top side, back behind my other teeth, there seems to be a new tooth just sticking out of the side of my gum. It appeared a few months ago. What is this, and is it normal?
