Stains, discoloration, and yellowing fade from careworn chompers during in-office LumiBrite and Zoom! treatments, brightening smiles up to seven or eight shades. To kick off one of three Zoom! sessions, a technician applies a layer of whitening gel to exposed grins, then shines a specially designed UV light to kick through residues of coffee, tea, and invisible ink. In a 30-minute LumiBrite session, a 35% hydrogen peroxide solution forms oxygen bubbles to scrub teeth’s microscopic pores, foaming away stains in a 30-minute session under a sapphire plasma arc light. Both treatments are overseen by Lincolnway Dental Center’s Dr. Young Kim, a 20-year veteran of anticavity combat, and several highly experienced ceiling lights.
