Arm & Hammer Enamel Care Whitening Toothpaste is the ideal choice for those of you who want a daily tooth replenishing treatment. It contains fluoride to strengthen your teeth and fight cavities. It is the only toothpaste that also restores your surface enamel and whitens too with the help of innovative patented technology with liquid calcium. Liquid calcium helps to remineralize your teeth by binding itself to the tooth surface, and it fills in tiny cracks and crevices resulting in strong, smooth surface enamel which in turn increases the gloss of your teeth, as well as naturally and gently whitening. The key ingredient, baking soda, gently cleans your teeth to avoid plaque build-up and gently removes stains, leaving your teeth feeling unbelievably clean and fresh.
