Dental extractions are performed for a wide variety of reasons. Tooth decay that has destroyed enough tooth structure to prevent restoration is the most frequent indication for extraction of teeth. Other indications are related to problematic impacted (wisdom) teeth, the prevention of future infection and to make space for orthodontic treatment.
During an extraction, special instrumentsand techniques are used to make the extraction the least traumatic and to preserve as much bone as possible. For example in cases where the roots of the tooth are severely flared the tooth may need to be sectioned to divide the roots and facilitate removal.
