Excessive exposure of the gums known as "gingival smile" is a concern affecting a large percentage of the population, according to some studies with a prevalence ranging from 10.5% to 29%.
It is a condition in which an overexposure of the maxillary gums is present during smiling.
The correct diagnosis and determination of its etiology are essential for the choice of the right treatment.
Hyperactivity of the lip elevating muscle is one of the main causes of a gummy smile. Indeed, several techniques have been proposed for its treatment.
Upper lip repositioning is a simple surgical procedure designed to correct a gingival smile due to hypermobility of the upper lip.
The purpose of the procedure is to limit the retraction of the lifting muscles of the upper lip in order to minimize gum exposure and thus reduce this gingival smile.
