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.
Dry socket is a complication of having a tooth pulled (tooth extraction). The socket is the hole in the bone where the tooth used to be. After a tooth is removed, a blood clot forms in the socket. This protects the bone and nerves underneath as it heals. Dry socket occurs when the clot is lost or does not form well. The bone and nerves are exposed to the air. This causes pain and delays healing.
