The Answer is: YES
Crest Whitestrips have been found safe by numerous clinical studies and have been approved by the FDA in the United States which has some of most strict safety guidelines in the world.
Does the hydrogen peroxide in Whitestrips cause cancer?
There is no evidence that hydrogen peroxide causes cancer in humans. The FDA and Health Canada and scientific experts at the World Health Organization have reviewed the data on hydrogen peroxide and neither has ever concluded that hydrogen peroxide is carcinogenic. Hydrogen peroxide is a safe and trusted ingredient that has been used for years in first aid products, mouthwashes and facial cleansers.
Yes. Crest 3D White Whitestrips contains hydrogen peroxide, the same enamel-safe ingredient dentists use for tooth whitening. Extensive testing has shown the product to be safe when used as directed.
