Bone grafting, normally a minor surgical procedure done in the dental office, is used to build up new bone in the area of your jaw that is used to hold the teeth. A small incision is made in your gum to expose the bone beneath it, and then grafting material is added. Most often, the grafting material is processed bone that serves as a scaffold, around which your body will actually deposit new bone cells. The grafting material will eventually be absorbed by your body and replaced by your own new bone.
The grafting material needed can come from a variety of sources. Sometimes it comes from your own body. Very often, however, it is bone from an animal or human donor that is processed by a laboratory to make it sterile and safe. Grafting material can even be synthetic. It comes in a variety of forms: powder, granules, putty or even a gel that can be injected through a syringe.
