A dental extraction (also referred to as tooth extraction, exodontia, exodontics, or informally,tooth pulling) is the removal of teeth from the dental alveolus(socket) in the alveolar bone. Extractions are performed for a wide variety of reasons, but most commonly to remove teeth which have become unrestorable throughtooth decay,periodontal diseaseor dental trauma, especially when they are associated with toothache.
