Recession of the gums may be caused by many factors, including heavy toothbrushing or clenching of the teeth. Sometimes, recession causes the tooth root to become exposed, giving your teeth a longer appearance, and making you look older than you are. As the gum that protects the root surface of the tooth is lost, not only does it create an esthetic deformity, it makes the tooth more sensitive to changes in temperature, touch, and to proper oral hygiene techniques. The exposed root surfaces also are more susceptible to cavities.

Gum grafts are designed to cover exposed roots, to reduce further gum recession and to protect vulnerable roots from decay.
