A gum augmentation is a common dental procedure often performed following a tooth extraction to help recreate the natural contour of the gums and jaw. This is accomplished with bone grafting or gum transplantation. The alveolar ridge of the jaw is the bone that surrounds the roots of teeth. When a tooth is removed, an empty socket is left in the alveolar ridge bone. Usually this empty socket will heal on its own, filling with bone and tissue. Sometimes when a tooth is removed, the bone surrounding the socket breaks or shrinks upon healing.
