Gum grafts are used when the gums have receded, and it is necessary to cover a portion of the tooth with tissue. As gum disease progresses, it causes the gums to pull back, which exposes more of the tooth. Having the tooth exposed can be a problem for many reasons because it could lead to other dental issues and even the loss of the tooth.
During the gum graft treatment, the dentist will take a portion of tissue from the roof of the mouth. That tissue will then be fitted over the exposed area and stitched into place. By covering the root of the tooth and strengthening the area with the extra tissue, you can reduce the risk of serious complications from gum recession.
