Aquafresh Fluoride Toothgel iso-active Foaming Gel, Whitening, Lasting Impact, 4.3 Oz (Pack of 4)

Aquafresh Iso-Active Whitening doesn't look like an ordinary toothpaste, and it doesn't act like one either! Given that 40 percent of your tooth surface is hidden between your teeth, getting your mouth healthy and clean can be a challenge. Iso-Active's revolutionary gel activates the moment you start brushing, transforming into a micro-fine foam penetrating hard-to-reach places around your mouth, protecting between your teeth and giving you a whole-mouth clean.
