White Trays

Aquafresh White Trays are another one of the teeth whitening products which works very well. The are direct competitive products against Crest's Whitestrips. The Aquafresh trays have the advantage of being able to get in between the cracks and grooves in the teeth, because a gel is used instead of a strip. However, this also creates some negative effects. The gel is hard to control, so spillage on to the gums is very easy, causing burning and tissue damage. Otherwise, this product works especially well.

Whitestrips

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.
