The first day is the worst. You mouth will be numb for a couple of hours, so no pain. There will be a lot of gauze changing, ice, and blood. It's gross but that is about it. Make sure to STAY ON TOP OF YOUR PAIN MEDICATION for the first few days. I am on percocet and it's kept it 100% manageable.
Eat cold and soft things. Do not suck on anything or spit (this can cause you to get a dry socket). Also you won't be able to ejaculate due the medication they put you on.
I just got mine out on Thursday.
