If the blood clot does not form or falls out, a dry socket occurs (D). No new bone forms, and the nerves are exposed, causing pain. (Illustration by GGS Inc.)

Other Information

A dental extraction (also referred to as exodontia) is the removal of a tooth from the mouth. Extractions are performed for a wide variety of reasons, including tooth decay that has destroyed enough tooth structure to prevent restoration. Extractions of impacted or problematic wisdom teeth are routinely performed, as are extractions of some permanent teeth to make space for orthodontic treatment.
