Gummy smile is a phenomenon that when some people smile, their upper lip elevates too far above their upper teeth, exposing gums and producing an unattractive smile. One cause is the hyperactive muscle which elevates the upper lip. It can also be aggravated by a thin upper lip that further contributes to the problem by exposing the upper gum even more. Treatment with botulinum toxin injections to reduce the activity of the muscle that elevates the upper lip can correct a gummy smile.
