I had all four removed. It was kinda stuffty. I didn't swell up much and I was kind of laid on my ass for two-three days, and then I slowly returned to normal over the course of about two weeks. Couldn't go off pain meds for about two and a half weeks without slightly incapacitating pain.
Also be careful about keeping your socket clean of food stuff. stuff builds up in there if you're not careful and it's grosssss.
Got my wisdom teeth out about two months ago and I'm still kind of picking stuff out of there with my tongue, haha.
