Believe it or not, there is a growing trend of using activated charcoal for teeth whitening. Also sometimes known as activated carbon, you might think that it would stain your teeth instead of making them whiter, so if there any truth behind this teeth whitening tip?

What is Activated Charcoal?

Activated Charcoal is also known as activated carbon and is quite different to regular charcoal which you might use on the BBQ. Activated carbon usually starts life as charcoal which is then processed in such a way to be riddled with small pores that increase the surface area many times over.

These tiny pores and large surface area make the activated charcoal highly adsorbent and with further chemical treatment enhanced even more.

In industry, activated charcoal is mainly used in filters or purification processes but it also has medical uses too. The most common is to treat poisonings and overdoses by binding to the toxin to prevent absorption by the body.

Specifically stains caused by tannins that you might find things like wine or tea for example.
