NYT: 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. A painful gingivectomy is an operation to remove some of the extra gum tissue.
In the past, surgery was the main treatment option, but that is often costly. 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.
Now people are going another route: onabotulinumtoxinA, otherwise known as Botox. In contrast to surgery, Botox is quick and easy, doctors who do the procedure say.
