If you regularly scroll through social media posts, you've probably come across a photo or two of a smiling mouth with teeth that are covered in what looks like a black foam.Charcoal toothpasteis a hot topic, and it might have you wondering if you should trade in your regular toothpaste for a tube of black paste. But does charcoal teeth whitening work?
What's in Charcoal Toothpaste?
As you might guess, a key ingredient in charcoal toothpaste is charcoal. It's not the same charcoal you'd find in an artist's toolbox or in a bag of briquettes meant for the grill, though. The charcoal used in toothpaste is what's known as activated charcoal.
According to a research study published in the International Journal of Engineering Research & Technology (IJERT), raw materials used in production of activated carbon includes Olive tree wood, Almond, tree pruning, Corncob, Coconut shells, Sawdust, Rice husk. The big difference between the two is that during production, activated charcoal is exposed to a special gas that causes it to develop large pores or spaces. Those large pores make the charcoal more absorbent, allowing it to soak up a variety of substances.
Beyond the activated charcoal, there could be any number of other ingredients in charcoal toothpaste. You might find mint flavouring, coconut oil or baking soda in a toothpaste with charcoal. Some do not contain fluoride, but some do. Others aren't even in toothpaste form, but come as tablets or powder.
