A dental extraction is the removal of teeth from the mouth. 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. Sometimeswisdom teeth are impacted and may cause recurrent infections of the gum. In orthodontics if the teeth are crowded, sound teeth may be extracted 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 usinglocal anesthetic injections to eliminate painful sensations. Local anesthetic blocks pain, but mechanical forces are still vaguely felt. 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.
Reasons to recieve Dental Extractions are:
- Severe tooth decay or infection Supernumerary teeth which are blocking other teeth from coming in.
- Severe gum disease which may affect the supporting tissues and bone structures of teeth.
- In preparation for orthodontic treatment.
- Insufficient space for wisdom teeth.
- Cosmetic; teeth of poor appearance, unsuitable for restoration.
