Whiten Your Teeth, Quickly and Easily. The easy two-step prime and whiten application process enables two powerful formulas to work together in a way that simply is not possible with single-step whiteners. The secret is our exclusive Pre-Whitening Gel, a clear, flavorless primer that empowers our Smile Whitening System formula to whiten teeth in even less time, while minimizing sensitivity. Both steps come in convenient, hygenic single-doses. Used alone, Smile Whitening System whitens teeth beautifully in just seven days. And now, you can go whiter, faster with the power-packed duo in four-day Speed Whitening System.
