Crest Whitening Strips Directions

Several teeth-whitening kits are available at a fraction of the cost of a professional whitening. For example, Crest whitening strips can brighten your teeth if you use it consistently, and it is safe to use when the kit's directions are closely followed. Whitening strips work by covering the teeth with a thin film coated in peroxide, which safely bleaches unwanted stains.
