I had all 4 of mine removed in one go probably 8 years ago now. I saw an Oral Surgeon who did a great job. I believe they were all impacted, but I could be wrong....they were breaking the surface.
Afterwards I can barely remember my dad driving me home in my doped up state and putting me to bed. Hours later I woke and tried to go to sleep on the bathroom floor, about 1/2 way in the hallway and 1/2 way in the bathroom - I wanted to be close to the sink to spit out the blood. After sleeping off the drugs for a few hours I was feeling pretty good. I ate a lot of applesauce and soft foods. I never took any of the percocet they gave me, just stuck with Advil.
I had a friend get hers done at the same time and she was sick for 2 weeks, was dizzy and throwing up for probably 3 days. She had horrible dry sockets!
Guess I was super lucky or just had a great Oral Surgeon.
