Longer teeth or exposed roots can look unsightly. Exposed root surfaces may increase your sensitivity to hot, cold or sweets. There may also be an increase of risk for cavities when root surfaces are exposed. Tissue graft can be used to cover roots or develop gum tissue which is absent due to excessive gum recession. A soft tissue gum graft can reduce further recession and bone loss. In some cases, it can cover exposed roots to protect them from decay and improve the aesthetics of your smile.
