A dental Extraction is the removal of a teeth from the mouth. 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. Extraction of impacted or problematic wisdom teeth are routinely performed, as are extractions of some permanent teeth to make space for orthodontic treatment.
Surgical removal of impacted wisdom teeth is the removal of impacted third molars that normally grow in at around age 18 to 20 years.
