Colgate MaxClean SmartFoam is designed with a special formula that foams 30% more as you brush (vs. a leading fluoride toothpaste). It gets in between teeth and around gums, helping to remove bad-breath germs even in tough to reach spaces. Colgate Max Clean with Whitening Foaming Toothpaste also fights cavities while the Effervescent Mint flavor helps freshen your breath.
