Colgate Optic White Platinum TV Spot, 'Favorite Foods' Feat. Alton Brown

Food science expert Alton Brown says it's a fact that your favorite foods, including wine, can deeply stain teeth. The TV host uses a blackboard to show how ordinary toothpaste only whitens the surface of teeth, but says Colgate Optic White Platinum is different. Alton claims the toothpaste uses hydrogen peroxide to deep clean teeth and give you a smile that's four shades whiter.
