Atlanta Tooth Whitening Gum Grafts Gum grafts are much the opposite of gum contouring.  In cases where there is too little gum tissue an appearance of teeth that are too long can occur and this can be just as unnatractive as too much gum tissue.  To remedy the situation a gum graft either uses gum tissue in an adjacent are or gum tissue from the roff of your mouth to cover the exposed root.  This is called a root coverage gingival graft. email: info@atlantatoothwhitening.com Atlanta Tooth Whitening - Home
