Gum contouring, or gum reshaping, is a cosmetic dental procedure that reshapes the gum line by removing excess gum tissue or correcting unevenness to create a more balanced, uniform, and attractive smile, often addressing “gummy smiles” or asymmetrical gum lines using scalpels or lasers. Performed by dentists or periodontists, it’s typically a quick in-office treatment that offers permanent cosmetic results, improving both aesthetics and oral hygiene by making teeth appear longer and easier to clean, though risks like sensitivity can occur if done improperly.
