Dry socket, (also called Alveolar Osteitis), is a complication that sometimes happens after a tooth has been extracted. Usually, a blood clot forms where the tooth had been. The blood clot acts as a scab and is necessary to protect the underlying bone, tissues, and nerves as the extraction area heals. If the blood clot falls out too soon, the underlying structures in the jaw (including the nerves) become exposed and painful. Without proper treatment, the extraction site may become infected. Dry Socket is usually treated with special packing material and antibiotics if an infection has developed. If you think that you have developed a dry socket after tooth extraction, tell your dentist or oral surgeon immediately.
