If the main cause of your gummy smile is hyperactivity of your upper lip, then anti-wrinkle injections could help. A gummy smile can be effectively corrected with Botulinum Toxin. It's a quick and simple treatment and a small amount of Botox can be placed strategically to reduce excessive gum showing.
Botox or other brands of botulinum toxin, such as Bocouture, Azzalure, Letybo and Nuceiva will relax the muscles causing hyperactivity so the lip is repositioned and hides your gums.
