According to an increasing number of YouTube videos and social media posts, one of the easiest, most effective way to whiten your teeth is to brush them with pitch-black activated charcoal. It sounds like somewhat of a paradox, but some users claim a single brushing can have amazing results.
Activated charcoal has long been used in medical settings to treat poisonings and drug overdoses. Unlike the charcoal we use for barbecues, this stuff is created when carbon is treated with an oxidizing agent, which results in a fine dust with millions of pores and an immense surface area. It’s these pores that give activated charcoal its sponge-like qualities, reducing the body’s absorption of toxic substances by an estimated 47 percent. It’s not the most specific absorber of substances,though, meaning it will absorb both good and bad substances in your stomach, but as long as you consume lots of water after ingesting it, you should be fine.
But while the toxin-absorbing properties of activated charcoal are well documented, its recent uses as an edible food ingredient and teeth whitening agent are not. No charcoal-based teeth whitening products have been evaluated and accepted by the American Dental Association (ADA) until now, but that hasn’t stopped proponents from recommending it as an excellent all-natural way to get a shinier smile.
