Crest Whitestrips are an excellent teeth whitening product and are highly effective. They work by holding hydrogen peroxide against the teeth for a long period of time. However, these products are not perfect; they do, unfortunately, slide off the teeth easily, spilling bleach into the mouth. Obviously, the whitening effect is diminished when this happens. The Crest Whitestrips family contains Classic, Premium, Pro Effects, Advanced Seal, Daily Whitening Multicare, and Supreme.
