SmartMouth Premium Zinc Ion Toothpaste combines zinc ion technology with fluoride to strengthen tooth enamel and to help with dental plaque and cavity issues. SmartMouth’s teeth whitening toothpaste comes with a mild mint flavor and no aftertaste. For optimum dental care, brush thoroughly after meals or at least twice a day. Beating bad breath means dealing with the real source of bad breath—sulfur gas. If you are serious about dealing with bad breath, nothing works better than activated zinc ion technology. SmarthMouth’s dual formula combines a sulfur eliminator and a zinc ion activator to release billions of zinc ions. Activated SmarthMouth clears away existing sulfur gas and its new production for an additional 12 hours. SmarthMouth is the only activated formula that deals with the real source of bad breath for a full 24 hours. This toothpaste for sensitive teeth is dentist recommended.
