When recession of the gingiva occurs, the body loses a natural defense against both bacterial penetration and trauma. When gum recession is a problem, gum reconstruction using grafting techniques is an option. Many times gum recession also results in a cosmetic defect and a “long tooth” appearance.
When there is only minor recession, some healthy gingiva often remains and protects the tooth; therefore, there is no treatment other than modifying home care practice. However, when recession reaches the mucosa, the first line of defense against bacterial penetration is lost.
In addition, gum recession often results in root sensitivity to hot and cold foods as well as an unsightly appearance to the gum and tooth. Gum recession, when significant, can predispose to worsening recession and expose the root surface, which is softer than enamel, leading to root cavitis and root gouging.
A gingival graft is designed to solve these problems. A thin piece of tissue is taken from the roof of the mouth, or gently moved over from adjacent areas to provide a stable band of attached gingiva around the tooth. Some patients may choose to use donor skin (Alloderm) instead of having tissue harvested from their palate. This option has the advantage of minimizing surgery and having a more comfortable healing time. The gingival graft is placed over the exposed portion of the root to which it will attach.
The gingival graft procedure is highly predictable and results in a stable healthy band of attached tissue around the tooth. Furthermore it helps protect the exposed and soft root surface.
