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.
Dry socket pain is often accompanied by bad breath and a foul taste in the mouth. With this onset of pain, it is obvious that proper healing has been interrupted. Dry socket is a condition in which there is inflammation of the jawbone (or alveolar bone) after a tooth extraction. It is also referred to as alveolar osteitis and is one of the many complications that can occur from a tooth extraction.
