The Professional Whitening Gum contains Calprox®, our unprecedented science, a proprietary formula of encapsulated calcium peroxide and minerals. Calprox® gently and effectively dissolves the sticky bio-film from teeth, to which plaque, bacteria, and stains (such as coffee, tea, tobacco and red wine) adhere, without the risk of sensitivity. Cleans teeth and freshens breath. Great-tasting mint flavor and sweetened with 65% Xylitol for greater cavity prevention. No other added sugars. Studies show infants whose mothers chewed xylitol gum, with at least 65% Xylitol, had 70% fewer cavities at age 5 than those whose mothers didn’t. Guarantees the most effective way to consume the anti-cavity benefits of Xylitol. Free of silica, parabens, sulfates, known allergens, animal by-products and BPA. It’s also Kosher.
