A dental extraction is sometimes necessary when a tooth is broken or damaged to the point where it cannot be restored. The most common reason for extraction is tooth decay or breakage. However, infection, gum disease or extra teeth that may be blocking other teeth from coming in properly, are also reasons to perform extractions.

Simple extractions are performed on teeth that are visible in the mouth, and usually done under local anesthetic. Simple extractions require only the use of instruments when the tooth is being removed. Surgical extractions involve removing teeth that cannot easily be accessed.Teeth that have broken under the gum line or have not fully come in are usually extracted surgically. Surgical extractions almost always require an incision. The common procedure of having wisdom teeth removed is often performed surgically.
