Activated charcoal has been a popular ingredient in teeth whitening products for quite some time, but does it really work? The short answer is yes, but it’s complex.

A nice set of pearly whites can boost anyone’s confidence. Unfortunately, our teeth are porous and tend to be stained by dark foods and liquids like coffee, tea, and wine. Of course, you can have them professionally whitened, but that’s certainly not the most affordable option.

Adding activated charcoal to your oral health routine can whiten your teeth, and save you some cash, to boot! Below, we’ll break it all down as well as recommend some activated charcoal pastes and powders.

What Exactly Is Activated Charcoal?

Activated charcoal is a form of carbon that’s been specifically processed to be highly absorbent. Manufacturers employ carbon-rich elements, such as wood, coconut shells, and peat, and heat them to very high temperatures in the presence of a gas.

This process causes molecular changes in the material resulting in the formation of tiny pores that increase the surface area, and thus, the degree of absorption. For reference, a teaspoon of activated charcoal has a surface area equivalent to that of a football field!

Emergency rooms are commonly equipped with this substance to treat cases of overdose and poisoning. Over-the-counter tablets and capsules of activated charcoal are often used to treat flatulence, indigestion, and kidney disease. However, there isn’t enough scientific evidence to support these practices.

Can Activated Charcoal Whiten Your Teeth, and Is It Safe?

In short, yes, activated charcoal can whiten your teeth but only to a certain extent. As we mentioned above, it’s highly absorbent and also mildly abrasive.

Teeth are also porous, which is why they lose their brightness over time. However, they’re protected by a layer of enamel, a highly resistant calcified tissue. So, in order for a substance to whiten your teeth, it has to work both on surface-level stains as well as on those beneath the layer of enamel.

Activated charcoal only works on stains present on the surface. As a result, the effects are limited and temporary. So while it might not have the same effect as professional teeth whitening, it can help boost the brightness of your smile in the short term.

Activated charcoal as a teeth whitening substance has no known serious side effects. Nevertheless, it should be used with caution.

Given its abrasive nature, it should only be used twice a week at most to prevent damage to your pearly whites. Given its black color, there’s a risk of accumulation of charcoal on cracks and crevices in your mouth, which could ultimately stain your teeth. It’s always best to rinse your mouth thoroughly after every use.

Powder or Paste?

As there hasn’t been a lot of research done on the topic, it all comes down to personal preference. Whether you use activated charcoal powder or toothpaste, you’re bound to end up with a brighter smile.

Below, you’ll find a few options to check out if you’re looking to give it a try.
