Soft Tissue Grafting (Gum Grafting)
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 all that may be required is to modify home care practices. However, when recession progresses beyond 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 loss of tooth or root structure.
Before and After Soft Tissue 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. The gingival graft may be placed in such a way as to cover the exposed portion of the root.
The gingival graft procedure is highly predictable and results in a stable, healthy band of attached tissue around the tooth. Tissue may also be obtained from a tissue bank instead of from the roof of the mouth.
Here is an example of gingival recession treated by using graft material from a tissue bank without the need to take tissue from the the roof of the mouth.
