Cosmetic gum shaping, also known as gum contouring or gingival sculpting, is a dental procedure that reshapes the gum line to improve the appearance of your smile. You might need it if you have a “gummy” smile, uneven gum line, or excessive gum tissue covering your teeth. This procedure enhances the symmetry and aesthetics of your smile by exposing more of your teeth and creating a more balanced gum line.
