A gummy smile is the term used when your gums are visible when you talk or smile. Your upper lip is pulled upwards by a muscle, exposing the gum. Some people who have a gummy smile don’t find it a particularly attractive. Additionally, gums can become more irritated if they are not protected by the upper lip.
The cosmetic physician uses a very thin needle to inject a dose of botulinum toxin into the muscle causing the upper lip to rise. The upper lip then drops slightly, thereby covering the gums. If necessary, the upper lip can also be treated with fillers for more volume, covering the gums even more.
