I had all 4 of mine out at once, and they were impacted. Take your drugs! I had minimal swelling because my nurse gave awesome advice. Borrow a pair of knee high stockings from a female or get a pair of men's knee socks. Nylons work better because they're stretchy. Put a ziplock bag full of ice in each one and tie it around your head so the ice is on your cheeks toward the back where your teeth were. The socks hold the ice in position. Just make sure to remove it every few hours to give your skin a chance to warm up. I didn't have a lot of swelling, but I did get a large bruise on each cheek, it looked like someone beat me up. Can't emphasize enough: take your drugs! Also don't play with your stitches. If you got the dissolvable kind, they'll fall out on their own and it feels weird.
