“What is the fastest way to heal a gum graft?”

Take warm water and vitamin C crystals and from the cup put some on your mouth and soak the area 1-2 min then repeat. Or lemon juice and warm water

Gingival grafts (gum grafts) can be done as free gingival grafts, meaning a layer of tissue from the roof of the mouth is harvested and transplanted at the intended site. At times, gum grafts are done with a layer of tissue directly under the surface (connective tissue graft), and also harvested from the palate or sometimes from other areas of the mouth. There is nothing you can do to "speed up" the healing process. Just try to keep your oral hygiene at optimal levels, maintain a soft diet, and follow the directions of your surgeon.
Good luck.
