Although gums do not grow back on their own, it is possible to treat gum recession via surgical methods, according to WebMD. Pocket depth reduction, regeneration procedures for lost tissue as well as bone and soft tissue grafting are commonly used for treating receding gums and improving the appearance of gums.
Pocket depth reduction involves folding back the tissue, removing bacteria from the interior pockets and securing the tissue back in place. Regeneration involves folding back the gum tissue and adding grafted tissue or membrane in an empty pocket for a better appearance. Usually, connective tissue from the roof of the mouth is used in soft tissue grafting procedures to fill out pockets and correct the look of receding gums, according to WebMD.
