When I got all 4 of mine pulled I got 2 dry sockets. One of the worst experiences ever, if I wouldn't have gotten dry sockets it would have been a peice of cake.
The throbbing pain was awful. What also sucked was they stuffed medicated gauze into the sockets, which gave me almost instant relief from the pain, but it gave me the worst taste in the back of my throat. They changed the gauze once, in all I think I had gauze in them for about a week, along with the absolute horrible taste that came along with it. Dry sockets suck ass.
