Many parents are surprised when their children’s primary incisors are lost and replaced with larger, darker, and yellower permanent incisors. The primary (deciduous) teeth are usually so white that they are known universally as “milk teeth.” When parents are told the facts about the normal color differences between the respective dentitions, and how apparent that is in the “esthetic zone,” they usually are quite disappointed. However both parents and their children are pleased to learn about dental bleaching and how successful it can be for children and teens.
