Explore current insights on tray bleaching, in-office bleaching, and OTC-bleaching based on published research and clinical experience, including bleaching for children and older adults. In this course the participant will review bleaching examination components, understand hydrogen and carbamide peroxide differences, and identify differences between tray, in-office and OTC products and techniques. We will discuss treatment options for brown and white discolorations and nicotine stains and explore the treatment of tetracycline-stained teeth as well as evaluate the long-term safety of tray bleaching.
