The word is out.
Activated charcoal, also called activated carbon, is the best way to whiten teeth naturally without using conventional tooth whitening trays, gels, and strips that contain toxic chemicals that can damage tooth enamel over time and harm delicate gum tissue. Even professional tooth whitening at the dentist is not a good idea for those concerned with avoiding toxin exposure and preserving their long term oral health.
It may seem odd to use black powder to whiten teeth, but it really does work.
Activated charcoal is so effective because it aggressively absorbs tannins, the compounds found in coffee, tea, tobacco, herbal teas, blueberries, wine, spices, and other foods that stain teeth. It does not, however, lock onto minerals like calcium in our teeth which is why it won’t harm tooth enamel even if used every single day.
