Gummy smiles occur for a variety of reasons, most commonly a short upper lip, excessive gum tissue or small teeth, all of which are genetic.
Case 1 by dr Sina Salimi
Doctors who specialize in cosmetic procedures estimate that about 14 percent of women and 7 percent of men have excessive gingival exposure when smiling.
In the past, surgery was the main treatment option, but that is often costly and painful. Doctors sever the muscles that elevate the upper lip so it can no longer rise as high, or they do a crown lengthening procedure that cuts away gum tissue so the crown appears longer.
In extreme cases, they might perform orthognathic surgery, which repositions the upper jaw if it sticks out too much. But this can be complicated and can take up to two years to complete.
In contrast to surgery, Botox is quick and easy, says Dr Salimi at estetica.
