Creating a great looking smile is in large part dependent on the shape of the gum tissues. In some cases, excess gum tissues need to be reshaped to create a more cosmetically pleasing shape or contour. A similar cosmetic problem can be encountered if one or more teeth are too short. The procedure to correct these cosmetic problems usually is minor and often stitches are not necessary. The procedure can be thought of as a manicure for the gums.
