A gum graft increases the attached tissue and stops receding gums.
One graft technique is to take a thin piece of gum tissue from the roof of the mouth and place it at the base of the recession, to strengthen the attached tissue and prevent further recession. A root-covering graft may also be done, to cover the exposed root surface.
The success rate of these procedures is excellent and in most cases the benefits should last many years or even a lifetime, if you maintain good oral hygiene.
