Dry socket happens when the blood clot in the socket is dislodged, exposing bone and nerves. For the first 24 to 48 hours, avoid straws, smoking, carbonated drinks, and vigorous rinsing or spitting. Eat soft foods and chew on the other side. After 24 hours, rinse gently with warm salt water. If intense, throbbing pain starts two to four days later, call us right away.
