Before and after gum grafting
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, gym recession can predispose to worsening recession and expose the root surface, which is softer than enamel, leading to root decay.
A gingival graft is designed to solve these problems. Three or four different surgical techniques can be used to address gum recession. In some techniques, 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. Other times, we can use an acellular dermal graft (Alloderm or Perioderm) for the same purpose. The advantage of the dermal graft is that no palatal donor site is required. The choice of technique often depends on the anatomy, severity, and location of the recession.
