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 when used in moderation, and is formulated to be used in conjunction with a less abrasive non-toxic cleanser, like our detox toothpaste toothsoap.
Please note : While using a charcoal toothpaste periodically can reduce or eliminate stains on your teeth, charcoal toothpastes have the potential to wear down enamel if used excessively or if you brush too hard. This could expose the yellow dentin below your enamel. (This can also happen with any other type of abrasive, like salt or baking soda.)
Those with receding gums (exposed roots) and elder teeth with thinner enamel may be extra sensitive to charcoal toothpastes. Charcoal particles could accumulate in the small cracks of the enamel and the areas without enamel , possibly leaving teeth discolored or darkened around the edges or roots. While this is a temporary effect, it would definitely NOT produce the effect you’re hoping for… so, if in doubt, try a small amount first:)
