Smile is an important determinant of the facial attractiveness of an individual. A perfect smile is an immaculate harmony between the pink gums and the white teeth. A normal smile has 1–2 mm of gingival display from the lower border of upper lip to the gingival margin of upper central incisors. Greater than 4 mm of gingival display is aesthetically not pleasing for most patients and is known as excessive gingival display (EGD) leading to a gummy smile (GS).
A disturbance in the color of the gingiva gets highlighted in an individual with GS. A normal healthy gingiva appears coral pink, but physiologic variations may produce pigmented patches. Gingival depigmentation is a procedure performed to eliminate the pigmented superficial gingival epithelium.
