A dental extraction is a procedure that involves the pulling of one or more teeth. Extractions are sometimes required as treatment when a tooth is severely damaged beyond repair because it is broken, cracked or extensively decayed. Extractions are also sometimes recommended when a healthy tooth is not well-positioned or is nonfunctional or if a patient has severe gum disease. Extractions can be performed by a dentist or oral surgeon. In both cases, patients are anesthetized.
