A dental or tooth extraction is the removal of a tooth from its socket. Extractions are performed for a wide variety of reasons, but most commonly to remove teeth which can’t be restored due to tooth decay, periodontal disease or dental trauma; especially when they are associated with toothache.
Tooth extraction is usually relatively straightforward, and the vast majority can be usually performed quickly while the individual is awake by using local anaesthetic injections to eliminate painful sensations. A local anaesthetic blocks pain. Some teeth are more difficult to remove for several reasons, especially related to the tooth’s position, the shape of the tooth roots and the integrity of the tooth.
Extractions are often categorized as “simple / routine” or “surgical”.
Simple or routine extractions are performed on teeth that are visible in the mouth and require only the use of instruments to elevate and/or grasp the visible portion of the tooth.
Surgical extractions involve the removal of teeth that cannot be easily accessed, either because they have broken under the gum line or because they have not erupted fully. Surgical extractions almost always require an incision. In a surgical extraction, we may need to elevate the soft tissues covering the tooth +/- bone removal. Frequently, the tooth may be split into multiple pieces to facilitate its removal.
