Dental Extractions

A dental extraction is the removal of teeth. Extractions are performed for a wide variety of reasons, but most commonly to remove teeth which have become unrestorable through tooth decay, periodontal disease or dental trauma; especially when they are associated with toothache. Sometimes wisdom teeth are impacted (stuck and unable to grow normally into the mouth) and may cause recurrent infections of the gum (pericoronitis). In orthodontics if the teeth are crowded, sound teeth may be extracted (often bicuspids) to create space so the rest of the teeth can be straightened.

Tooth extraction is usually relatively straightforward, and the vast majority can be usually performed quickly while the individual is awake by using local anesthetic injections to eliminate painful sensations. Local anesthetic blocks pain, but mechanical forces are still vaguely felt. 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. Dental phobia is an issue for some individuals, and tooth extraction tends to be feared more than other dental treatments like fillings. If a tooth is buried in the bone, a surgical approach may be required.
