A gummy smile is a smile in which more gum tissue is visible than usual when a person smiles. It may occur due to factors such as excessive gum tissue, the position of the upper lip, tooth size, or the way the upper jaw has developed. While a gummy smile is generally not a medical problem, some people may seek treatment to improve their smile aesthetics and confidence. Modern gummy smile treatment is planned according to the underlying cause and may include gum contouring, orthodontic treatment, or other appropriate cosmetic procedures. A professional dental evaluation can help determine the most suitable approach for achieving a more balanced and natural-looking smile.
