Gummy smile can have a negative effect on the aesthetics of your smile.
There can be a number of causes for this condition. Should the condition be due to the muscle that controls the movement of your upper lip being hyperactive, causing your upper lip to rise higher than normal, or due to a thin upper lip these can be corrected with the use of wrinkle and line treatments via injection.
The corrective procedure is achieved by injecting both sides of the junction of the nostril and nose to mouth fold to weaken the muscles. Over a duration of 3-4 days, elevation of the upper lip will become less, showing less gum when smiling.
