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.
When there is only minor recession, some healthy gingiva often remains and protects the tooth, so that no treatment other than modifying home care practices is necessary. 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 of the gum and tooth. When significant, gum recession can predispose to worsening recession and expose the root surface, which is softer than enamel, leading to root caries and root gouging.

Gum Grafting Overview
For a brief narrated overview of the gum grafting process, please click the image below. It will launch our educational MiniModule in a separate window that may answer some of your questions about gum grafting.
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. If the area of recession is not too broad, the gingival graft may be placed in such a way as to cover the exposed portion of the root. When there is already underlying bone loss, root coverage is not an option.
The gingival graft procedure is a predictable procedure which results in a stable, healthy band of attached tissue around the tooth and in certain cases achieves some root coverage.
