Hi Tia. Good questions. From what I have read, not all teeth extracted the general way cause a cavitation, but I don't know why.

I had jaw surgery because I once had an infection and then had the tooth filled up with amalgam, and the infection was left in the socket. My dentist took the tooth out and then drilled out the old infection. I didn't have a stitch, so I think they "play it by ear" when to give one or not. I didn't have one for my wisdom tooth either, where as some people do. I had aloe vera gel to put on it and the hole closed up amazingly quick. I had it in April and I can now chew that side again (only just been able too).
