Teeth need to be extracted for a number of reasons; the most common being advanced tooth decay or periodontal (gum) disease.

If a tooth has decayed to a point where restorative procedures will not save it, then an extraction is necessary to protect the mouth from further infection and damage. Extractions are also performed on patients who have impacted (un-erupted) teeth or on occasion, for younger patients who do not have enough room to receive orthodontic care without removal of some teeth.
