Crest 3D White Whitestrips Advanced Vivid
Over-the-counter teeth whitening
Crest 3D White Whitestrips Advanced Vivid is the best over-the-counter whitening system because it is easy to use and lightens teeth about three shades, on average. Designed to be worn for 30 minutes a day over the course of two weeks, these bandage-like strips adhere to teeth and hold bleaching solution in place. Although Whitestrips are available for over-the-counter purchase, experts recommend consulting with your dentist first.
