“Generally, I consider the thin upper lip and 'gummy' smile to be most reliably treated with nonsurgical options using a combination of Botox and filler,” says Great Neck, New York, otolaryngologist Dr. Sean Alemi in a RealSelf Q&A.Â
The injectable filler increases the volume of the upper lip, minimizing the amount of visible gum for six months to a year (depending on how your body metabolizes the filler).Â
Botox or Dysport can also be injected directly into the muscles, to reduce the lift of your upper lip when you smile, but it can create asymmetry if it’s not done correctly. The effect lasts three to four months.Â
A gum lift is another option, but it may not be enough to correct a significantly gummy smile.Â
Orthognathic surgery, or corrective jaw surgery, may also be an option, depending on your anatomy. It’s much more invasive, is more expensive, and has a longer recovery time—but your results will be dramatic and permanent.
