Dry socket is more likely to occur following a difficult tooth extraction. It is thought that excessive force applied to the tooth, or excessive movement of the tooth burnishes the bony walls of the socket and crushes blood vessels, impairing the repair process.
It is known as dry socket as after the clot is lost, the socket has dry appearance because of exposed bone. The blood clot helps in stopping the bleeding and lays framework for new tissues to develop there but in case of dry socket, the clot is dislodged and the bone is exposed.
