Teeth are sometimes infected or crowding other teeth in the mouth. When that happens, a dentist may refer you to an oral and maxillofacial surgeon for extraction. If a tooth is so decayed it can not be saved, or the tooth is too badly damaged from trauma, it must be removed.
Sometimes teeth are extracted before braces are put on to alleviate a crowded mouth. If a tooth is impacted or can not break through the gum, your dentist may recommend removal.
Excessive tooth decay that has compromised the integrity of the tooth is another reason a tooth may be removed. Infection, risk of infection, an abscess or damage to the pulp (interior of the tooth) are other reasons a dentist may recommend having a tooth extracted.
People who are receiving chemotherapy, having an organ transplant or are in other ways immunocompromised also may be referred to an oral surgeon to have compromised teeth removed to prevent infection.
