I had 8 upper veneers done. The purpose was to elongate my natural teeth at the Biting Edge so they show more when i smile/talk. My dentist did the opposite procedure: lifted my gumline UPWARDS 3mm+. 1.Does gum ever grow back after laser crown lengthening? 2.Can a gum graft lower the gumline back to the original state? 3.Is it possible to graft over a veneer? PS. The dentist wont return any calls.I am filing a complaint to the royal college.
