When I had my wisdom teeth out, they were all beneath the gum, so all were cut out. I was super careful, but since I threw up (in response to the anesthesia), I apparently threw up my clots, unbeknownst to me. They had me on Tylenol with codeine, so I took that as needed, until I ran out. I still had a little pain, so I was taking one Advil and one Tylenol. Went back for my two week checkup, and the doctor took one look and said, you have dry socket in two of your spaces, your nerves are exposed, how have you been surviving? When I said on a Tylenol and Advil, he looked at me with amazement. Then I had to go back daily to have gauze soaked in clove oil packed into my sockets for a week. Everything tasted like clove, I still can't stand the taste. That was ten years ago.
If you do have dry socket, it won't go away on its own. They still pack your sockets, but I think they use a synthetic oil now, not clove.
