How many units of Botox is needed to reduce the amount of lifting of the upper lip when smiling, so as to correct a gummy smile?

A: Botox for gummy smile

If you truly have a gummy smile, Botox is not the definitive treatment for you. Although it may be temporary, it could distort your smile slightly and create some asymmetry while you are at rest.

The treatment of a gummy smile is surgical, and I recommend consulting with a plastic surgeon and/or an oral surgeon trained specifically in orthognathic surgery, which is they type of surgery involved in treating you condition.

Best wishes.
