A smile with more than 2mm of exposed gum or gingiva is called a gummy smile. A gummy smile may not be aesthetically pleasing and could affect a patient’s self-confidence or cause them to hide or control their smile.
The non-surgical approach is wrinkle relaxing injections. During this procedure Botox is injected on each side of the lip. This weakens the hyperactive muscles and reduces the elevation of the upper lip, thereby reducing the inhibiting gummy smile.
Your new smile would last for about four to six months.
