Our Whitening Foam Toothpaste for AutoBrush provides one-step dual-action cleaning + whitening micro-foam. It neutralizes harmful acids before they damage teeth. Penetrates between teeth and along the gum line for a deep clean. Removes more carcinogenic plaque in hard-to-reach places than regular toothpaste due to its superior density. It fights & resists the contamination of processed foods and this foam can be used on its own as a mouthwash or as a perfect complement to the AutoBrush as a toothpaste.
