The most common reason for extraction is tooth damage due to breakage or decay. There are additional reasons for tooth extraction:
- Severe tooth decay or infection (acute or chronic alveolar abscess). Despite the reduction in worldwide prevalence of dental caries, it is still the most common reason for extraction of (non-third molar) teeth with up to two thirds of extractions.
- 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 (braces)
- Teeth which cannot be restored endodontically
- Fractured teeth
- Supernumerary, supplementary or malformed teeth
- Prosthetics; teeth detrimental to the fit or appearance of dentures
- Cosmetic; teeth of poor appearance, unsuitable for restoration
- Receiving radiation therapy to the head and neck area may require extraction of teeth in the field of radiation.
