Why Is Bone Grafting Necessary After a Tooth Extraction?

After a tooth extraction, the jaw bone is left with an empty socket where the tooth originally was. Immediately after extraction the body starts to heal the socket. If a bone graft is not placed. Within 2 – 4 years the jaw bone surrounding this empty socket usually suffers 40% to 60% in bone loss, a monumental decrease. A host of problems occur from jawbone loss, such as a receding jawline, loose and shifting teeth, bite collapse, and appearances of aging. Loose and shifting teeth occur due to a lack of support between the teeth; the empty space where extractions take place allows the teeth to shift.
With bone grafting, the dentist takes a synthetic material and places it in the empty socket where the extraction took place. The material acts as a scaffold where the bone and graft fuse forming bone, filling up the empty socket and stabilizing the teeth on either side of it. This highly successful procedure aids in preservation of the bone from the receding jaw and stabilizes the adjacent teeth. If an implant is desired, the bone graft allows for enough bone to support the implant. When the patient desires a three unit bridge, the supporting teeth are now stabilized. When the dentist performs advanced extraction therapy, such as placing the synthetic bone material into the socket; the height and width of the ridge is preserved. This allows a three unit bridge to be placed by having a fake crown (pontic) placed where the newly formed bone is and then having a crown on each side.
Bone grafting is by far one of the most successful procedures which allows the dentist to have better flexibility in creating a beautiful, full smile.
