When attempting to either restore a tooth or recreate a patient’s smile it may be necessary to increase the amount of tooth present above the gum in order to recreate a natural appearance. This can be done through crown lengthening. The procedure involves removing excess tooth tissue and, in some cases, bone may also need to be removed. It can help patients with gummy smiles to improve their smile as well as also correcting irregular gum margins to a more aesthetically pleasing situation.
