Crown lengthening is a periodontal plastic surgery, gum reshaping procedure in which gum tissue or bone is removed to expose a greater area of the tooth structure. This can be used for cosmetic purposes such as minimizing the appearance of a “gummy smile,” or prosthetic purposes such as exposing more tooth to support a crown or filling.
The gum is reduced or reshaped by moving small amounts of gum tissue in desired areas. The goal is to lengthen the appropriate teeth and create greater symmetry at the gum line.
Candidates for crown lengthening are those in good general health, specifically those with healthy gums. Those with a gummy smile, decay, or a crack near the gum line are also strong candidates. If you suffer from periodontal disease or have insufficient bone you may not be eligible for this procedure.
Healing time varies from patient to patient depending on the amount of tissue removed during the procedure.
