I got all four taken out at once under a general, felt great when I woke up. Blood drooling out my mouth on the car trip home, bandage with icepack wrapped around my head. Had a huge meal, then the anasthetic began to wear off and the pain was f*cking terrible. Not even the strongest painkiller helped in the 3-4 days proceeding that, coupled with the fact that my jaw had locked up and I could only open my mouth about a centimeter. Puffed up and bruised face, liquid diet for about two weeks (losing a bit of weight is a good side-effect.) Stitches desolved after about 2-3 weeks, holes closed over completely in about a year. All in all, so glad I got them out. Put up with years of pain. Now, nothing.
Do it.
