Extraction

A dental extraction, also referred to as tooth extraction, is the removal of teeth from the jaw bone. 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).

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. Local anaesthetic blocks pain, but mechanical forces are still 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 or trans alveolar approach may be required, which involves cutting the gum away and removal of the bone which is holding the tooth in with a surgical drill. After the tooth is removed, stitches are used to replace the gum into the normal position.

Common complication after tooth extraction is bleeding and pain. This problems often subsides spontaneously or with little intervention from dentist. Often numbness can remain due to accidental injury to the nerve during extraction.
