The gummy smile can make the smiler feel very self-conscious, often ruining the mirthful moment that is making them smile and laugh in the first place. There are several causes for a gummy smile, all of which, happily, can be treated.
In some cases, the muscle which elevates the upper lip can be hyperactive. In others, the cause can be that of a thin upper lip. And sometimes the gummy smile can be aggravated by combination of both of these factors.
With a Botox treatment, however, botulinum toxin injections can relax the upper lip muscle, leaving you to smile and laugh with confidence and laugh with abandon. The treatment will take effect over 3-10 days and then last for between 3 and 5 months.
