Stitches, also commonly called sutures, are used to put tissues back together after oral surgery or any complicated tooth extraction. There are two kinds of stitches, those which are absorbable (or dissolvable) and will break down harmlessly in the body over time, and those that are non-absorbable (or non-dissolvable) and must be manually removed by the surgeon.
An oral and maxillofacial surgeon or your dentist can remove (extract) a wisdom tooth. The procedure often can be done in the dentist's or surgeon's office. You may have the surgery in the hospital, especially if you are having all your wisdom teeth pulled at one time or if you are at high risk for complications.
