Gummy smile has various causes and a proper examination prior to treatment is vital.
Hyperactive muscle One of the common causes of gummy smile is a hyperactive muscle that pulls the upper lip more than it should, resulting in more gum visibility than is aesthetically pleasing.
Overgrowth of gum tissue Other causes of a gummy smile like overgrowth of gum tissue and dental development defects are better assessed by a dentist.
In cases where the cause is a hyperactive muscle, neuromodulators like Botulinum toxin is an amazingly quick and effective treatment.
