ACTIVATED CHARCOAL: Dental Benefits
Activated charcoal is not charcoal used in your barbecue (braii) grill :)
The porous surface of activated charcoal has a negative electric charge that causes positive charged toxins and gas to bond with it.
Essentially, activated charcoal is a form of carbon that acts like magnets for other particles, which it absorbs and is swept away when the charcoal is washed off. In theory, [it] binds to everything in its path—stains, tartar, bacteria and viruses. Surface stains, also known as extrinsic stains, come from the usual suspects: coffee, red wine, tobacco, and dark coloured foods.
Activated charcoal toothpastes are a rebirth of ancient medicine techniques. Activated charcoal can be used as a supplement to brushing with regular toothpaste for people who are seeking a whiter smile.
