A dental extraction (also referred to as exodontia) is the removal of a tooth from the mouth.
Extractions are performed for a wide variety of reasons, including tooth decay that has destroyed enough tooth structure to render the tooth non-restorable. Extractions of impacted or problematic wisdom teeth are routinely performed, as are extractions of some permanent teeth to make space for orthodontic treatment.
The most common reasons for extractions are:
- Severe tooth decay or infection (acute or chronic alveolar abscess). Despite the reduction in worldwide prevalence of dental caries, still it is the most common reason for extraction of (non-third molar) teeth.
- Extra 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 (braces)
- Fractured teeth
- Insufficient space for wisdom teeth (impacted third molars).
