Dry socket, also known as alveolar osteitis, is a painful condition that can occur after a tooth extraction. It happens when the blood clot that normally forms in the socket where the tooth was extracted becomes dislodged or dissolves, exposing the nerves and bone underneath.

Symptoms of dry socket typically include severe pain in the area where the tooth was extracted, a bad taste or odor in the mouth, and visible bone in the socket. The pain may radiate to the ear or jaw and may be accompanied by swelling. Dry socket can occur in any tooth extraction, but it is more common in lower wisdom teeth. Certain factors can increase the risk of developing dry socket, including smoking, poor oral hygiene, and the use of birth control pills.

Treatment for dry socket typically involves visiting the dentist or oral surgeon, who may clean the socket and place a medicated dressing to help relieve pain and promote healing. Pain relievers and antibiotics may also be prescribed. It's important to avoid smoking, drinking through a straw, or eating hard or crunchy foods until the socket has fully healed.

To prevent dry socket, it's important to follow the dentist's instructions for aftercare following a tooth extraction, including avoiding smoking, drinking through a straw, and rinsing the mouth too vigorously in the first few days after the extraction. Proper oral hygiene can also help prevent the formation of dry socket.
