Can Gum Grafts Be Performed on Teeth with Existing Restorations at the Gum Line / Existing Bonding on Root Surfaces?

If the purpose of gum graft is to cover the exposed roots, the resin bondings will need to be removed. The gum graft does not attach to the resin fillings , porcelain crowns.  It will only attach to the root surface.  Sometimes 100% root coverage with gum graft is not possible.  In that case, after  healing form the gum graft, Resin bonding could be used to cover the remaining portion of  roots exposed. sometimes the purpose of gum graft is not for root coverage, when the patient has lost the supporting bone between the roots of the teeth, root coverage will not be possible  In these cases, the purpose of gum graft will be to increase the tissue thickness to prevent further gum/ bone loss.  In this case, the existing resin bondings could be kept, and the sites could be grafted to thicken the tissues. It is best to have a consult with a Periodontist,  for a clinical exam and evaluation of Xrays.   

Quite a few questions in there...

1. normally bonding or such restorations are removed in order to enhance bonding. If the defect is deep, it can be restored with Geristore and then grafted.

2. Porcelain and metal cannot be grafted over at this time.

3. Grafts require nutrition (ie blood supply) from between the teeth so success often depends on an interdental papilla.
