Our activated charcoal is made from organic coconut shells, which have passed through very high heat to alter the inner structure of the charcoal, making it highly porous and negatively charged, so it can attract positively charged molecules to itself, such as tooth stains, toxins and plaque. This exceptional ability to adsorb (as opposed to absorb) accumulated plaque and other toxins, reducing or preventing systemic absorption, is also why it works so well at removing surface stains from coffee, tea, red wine, and berries. These results are different from that of a a tooth whitening or bleaching process, which also targets intrinsic (internal) staining. This is why using activated charcoal doesn’t cause tooth sensitivity as bleaching often does. The ultra-fine carbon powder is very gentle to teeth and is made to be used in conjunction with a non-toxic cleanser, like our detox toothpaste.
