Many people opt for laser- or light-enhanced whitening because it saves time and provides same-day results. Before treatment, expect a thorough examination to determine three things: the type of stains you have, the health of your teeth and gums, and potential sensitivity to bleaching and light. Whether your dentist offers laser- or light-based whitening often boils down to their experience and comfort level with a particular device. “There isn’t a major difference in the method or results from the different activators; its whatever activates the bleach,” says Atlanta cosmetic dentist Ronald Goldstein, DDS. “Some in-office solutions don’t even require light at all.”
