When gingival recession occurs, the body loses a natural defense against both bacterial penetration and trauma. Gum rebuilding using grafting methods is an alternative when gum recession is a problem.
When there is only a minor recession, some good gingiva often stays and protects the tooth, so there is no need for therapy other than changing home care practices.
However, the first line of defense against bacterial penetration is lost when the recession reaches the mucosa.
Additionally, gum recession often results in root sensitivity to warm and cold foods as well as an unsightly appearance of gum
and tooth.
When significant, gum recession may predispose to worsen recession and expose the root surface, which is softer than enamel, leading to root caries and root gouging.
