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. Adults and children 2 years of age and older: Brush teeth thoroughly preferably after each meal or at least twice a day or as directed by a dentist or physician. Children 2 to 6 years: Use only a pea sized amount and supervise child s brushing and rising (to minimize swallowing). Children under 2 years: Ask a dentist or physician.
