People with gummy smile tend to find this condition aesthetically unacceptable. Moreover, this type of smile is often associated with pronounced nasolabial folds.
People with gummy smile have a narrow upper lip and their upper incisors are visible. The thin upper lip may in some cases be slightly rolled up, exposing the whole upper gum line when smiling. Since interactions between perioral muscles are extremely complex, treatment effectiveness depends on three key factors: the physician’s experience, optimal patient’s suitability for the treatment and proper dosage. Generally speaking, the procedure should only be performed by experienced physicians.
