Extracting teeth can alleviate the pain associated with severely broken teeth, advanced periodontal disease, or deep cavities. Extractions are also used in preparation for orthodontics and making room for erupting permanent teeth.
Wisdom teeth begin to erupt around age sixteen. Most people do not have room in their mouth for these extra teeth and should have them removed. Not extracting wisdom teeth that are poorly positioned can cause decay on other healthy teeth or infection of the gums around the wisdom teeth.
