The laser light is absorbed by the melanin (dark pigment) in the skin, which then causes the cells to become heated to the point where they are harmed. The injured cells are flushed out of the body in a natural process, and what&apos;s left is the hue of the patient&apos;s skin that lays beneath the pigmentation. They will emerge from the procedure with gums that are clean, pink, and appear healthy, as well as a smile that is more radiant.
