If you don't follow their instructions and get dry socket you are in for a world of hurt. I had it because I didn't keep the gauze in long enough and the blood plug didn't form and stay in. that exposes the bone below the gums and hurts like holy hell. The doc gave me some stuff to plug the hole but it wasn't as good as the natural blood plug and I went through many days of suffering till the gums healed over. DO NOT use a straw or suck on a water bottle. Do what they say and you should be fine. I would ask for stitches for any extraction I have in the future.
