What is activated charcoal tooth powder?

My Magic Mud Activated Charcoal Tooth Powder for Whitening is a 100% natural oral care remedy that cleans, polishes, whitens, and detoxes your teeth. It features food-grade activated charcoal and bentonite clay. My Magic Mud® is completely flavorless, a little messy, and at first may seem a little weird! But we promise after you see and feel the results, you’ll love it as much as we do!
