I had oral surgery on Monday, so I'll tell you about that, but yours might be different from mine. Mine was a crown lengthening, so I have enough tooth to have the right margins for a crown to be put on it because I had a cavity right at the level of my gums under the old crown.
I drove myself in, then the assistant used some sort of gel on my gum to numb it. Then the doctor gave me a couple of numbing injections that numbed the lower right side of my mouth and waited while those took effect. While we were waiting, the assistant gave me my post operative instructions and the prescriptions for the pain medicine and the special germ-killing mouthwash that I needed to have filled after we were done.
Then just before the doctor started the surgery, he gave me more injections around the tooth but I didn't feel those at all. He cut my gums away from the tooth to expose the bone and used a scraper and a drill to remove some of the bone. When he was done, he sewed the gums back with a long suture.
I drove myself to the drugstore,then home. I took a pain pill so it could start working before the numbing medicine wore off. I felt like resting afterward, so I napped off and on for the rest of the day. I use the mouthwash twice a day after I brush my other teeth, but I don't brush the teeth where the surgery was done. I will go back in two weeks so they can check and make sure the gums healed correctly.
