A dry socket is caused by the partial or total loss of a blood clot in the tooth socket after a tooth extraction. Normally, after a tooth is extracted, a blood clot will form as the first step in healing to cover and protect the underlying jawbone. If the blood clot is lost or does not form, the bone is exposed and healing is delayed. In general, a dry socket is a result of bacterial, chemical, mechanical, and physiologic factors.
Instead of a dark blood clot, there will just be whitish bone. The pain typically starts about 2 days after the tooth was pulled. Over time it becomes more severe and can radiate to your ear. Other symptoms of dry socket include bad breath and an unpleasant smell and taste in your mouth. How Is Dry Socket Treated? You can take a nonsteroidal anti-inflammatory drug (NSAID), such as aspirin or ibuprofen, to ease the discomfort.
