I have heard of a dry socket. What is that?
When a tooth is removed, it leaves a socket or hole that later fills in with bone. When the tooth is removed, sometimes you dont get a good blood clot. When the clot does not form properly, it sloughs and leaves the walls of the socket dry or not covered by the clot. In other words, the bone that is the wall of the socket is not covered. This dry socket can be uncomfortable unless treated. Dry sockets occur more frequently with lower third molars than any other tooth, and they occur more frequently with very difficult impactions. However, the overall incidence of dry sockets is very low.
