The length of time it takes for a product to whiten your teeth depends greatly on the ingredients and the purpose of the toothpaste. If, for example, you use a new toothpaste like Colgate® Optic White™ Platinum White & Radiant, which contains hydrogen peroxide, you'll see results much more quickly than if you use a whitening toothpaste that contains only surface-stain removers. The latest in whitening is the new Colgate® Optic White™ Toothbrush + Built-In Whitening Pen which whitens teeth in two days.
Whitening your smile with daily brushing makes sense. You're brushing anyway, so you might as well whiten your teeth, too. By understanding what makes these toothpastes tick, you will have better control over which ingredients you use and how soon you can get a perfect smile.
