Teeth are extracted for a variety of reasons: Decay has reached deep into the tooth causing an abscess, infection has destroyed a large portion of the tooth or surrounding bone, periodontal (gum) infection, or there is not enough room for all the teeth in your mouth. Before a tooth is removed, the dentist will thoroughly review your medical and dental history and take the appropriate X-rays. X-rays reveal the length, shape, and position of the tooth and surrounding bone. A tooth extraction is a relatively routine procedure.
Wisdom teeth are the last molars on each side of the jaws. They are also the last teeth to emerge, or erupt, usually when a person is between 17 and 25. Since wisdom teeth are the last permanent teeth to erupt, there is often not enough room left in your mouth to accommodate them. This can lead to wisdom teeth that are impacted –teeth that are trapped beneath the gum tissue by other teeth or bone. If teeth are impacted, swelling, pain and tenderness may occur. Wisdom teeth that come in crooked or only partially emerge can also lead to painful infection. Teeth that are removed before they have fully developed roots have fewer complications. Therefore we recommend people between 15 and 19 have their wisdom teeth evaluated to see if they need to be removed.
