dental charcoal
Curious about charcoal toothbrushes?

Thinking about trying out a charcoal toothbrush? Activated charcoal has recently become popular in oral hygiene products as a natural way to whiten your teeth and detoxify your gums. So if you're reading this, you're probably wondering which charcoal-infused toothbrush is the best, or maybe whether or not it's even worth trying.

In order to help you choose the best toothbrush for your routine, we at have put together this article looking at activated charcoal brushes, in which we will answer the following questions:

  • Do charcoal toothbrushes work?
  • Are they safe?
  • What is the best activated charcoal toothbrush?
  • Is there a charcoal bristle electric toothbrush?

We hope that by the time you finish reading you'll have a better idea of how activated charcoal works to whiten teeth and whether you want to give it a try. If you do, we've also written a short review of some of the best and most popular charcoal toothbrushes currently on the market. So, let's get started by looking at the benefits and whitening effects of an activated charcoal toothbrush, and if it's even safe to use.

If you're already sold on the idea of activated carbon and just want a recommendation, you should think about the Burst sonic toothbrush. It has a powerful sonic motor that lasts weeks on a single charge. It's affordable compared to similar models from other brands. Most importantly, it makes use of charcoal-infused bristles in its toothbrush heads. The heads are even replaced every three months via a subscription service.

How does an activated charcoal toothbrush work?

Activated charcoal is a substance used to treat poisoning and purify water. It's also found in beauty and health products for things such as skincare, or kidney and gastrointestinal health. This is because activated charcoal is extremely porous and absorbs harmful microbes and toxins at a microscopic level.

Charcoal toothbrushes are also designed to take advantage of this effect. Their bristles aren't actually made entirely out of charcoal, but rather nylon that has been infused with charcoal. The idea behind these bristles is that they will whiten your teeth by removing stains gradually with consistent brushing.

We'll talk about the safety and effectiveness of charcoal in a bit, but this is meant to offer an alternative to potentially harmful methods to whiten teeth. You can read more about activated charcoal and how it is used in oral health in our activated charcoal article.

Are charcoal toothbrushes safe?

As always, safety is top priority. In short, hygiene products with charcoal are safe to use. People have used charcoal around the world as a detoxifying agent for many years. Doctors use it medicinally to counteract several types of poisoning. Using it for oral hygiene purposes isn't new either.

It may seem kind of crazy to think that putting coal in your mouth wouldn't be dangerous, but for years, before the dental toothpaste we all know, charcoal was one of several substances used to brush teeth. In fact, it wasn't as abrasive as other options (like salt) and therefore was less damaging to enamel.

Of course, it's not advisable to consume significant amounts of activated charcoal powder, and you should avoid inhaling it at all costs.

Do charcoal-infused toothbrushes work?

Could charcoal be the solution to a yellow smile?

We know that it's safe to use charcoal toothbrushes, but are they good for anything? Lots of people swear by them, but there isn't much scientific research on activated charcoal's whitening effect.

What's more, there have been no peer-reviewed studies focused on whitening from carbon-infused toothbrushes whatsoever.

So, we have to look at other studies for insight and, unsurprisingly, they give conflicting evidence. In a study designed to measure and compare the effectiveness of different whitening agents in toothpaste, activated charcoal showed an ability to whiten teeth. The study used teeth from cows that were stained with black tea, then measured the performance of different whitening agents after continued use. Though it was not the most effective of all, charcoal's whitening power was statistically significant.

Of course, another recent study did not find strong evidence to support charcoal whitening. This study also used bovine teeth, comparing the bleaching effect of charcoal with carbamide peroxide and regular toothpaste. It's worth noting that the study only looked at results after two weeks of brushing.

If we move outside the realm of whitening, we find an interesting study that did use charcoal toothbrushes. This study was focused on the antimicrobial properties of activated charcoal. They found that bristles infused with activated carbon had about half as much bacteria as regular toothbrush bristles after seven days of use.

Dentist's opinion on activated charcoal

Here's a video from Dr. Joe Nemeth, DDS, in which he talks a bit more about the potential risks and benefits of activated charcoal from a dental health perspective:

Using activated charcoal to whiten your teeth is the new craze! But does it actually whiten your teeth? What are the benefits of activated charcoal for teeth whitening? Are there any risks to using abrasive charcoal toothpaste? Dr. Nemeth answers these questions and more! Dr. Nemeth thinks that if it whitens your teeth significantly it could possibly be very abrasive. No long term studies about what activated charcoal does in the mouth have been completed. It could cause the enamel on your teeth to erode away, and it is likely to cause notching, or thinning of the tooth. It may also irritate the gums and cause the gum tissue to become red. Also if you have crowns, veneers, or fillings in your mouth you have to be very careful with ANY teeth whitening products. The FDA spends lots of time clearing drugs and other toothpastes. This powder certainly hasn't been cleared to be used in the mouth in any way. We don't know the long term effects of activated charcoal to whiten teeth, so Dr. Nemeth advises that you be careful and use this teeth whitening technique sparingly!

If you don't want to sit through the video, here's a quick summary of what Dr. Nemeth has to say:

  • Activated carbon probably does whiten teeth. However, the effect is probably the result of abrasive qualities.
  • Excessive use of abrasives can damage enamel or irritate gums.
  • Long-term studies haven't been done so we can't say definitively how well it will work.
  • If you have crowns or veneers, they probably won't whiten as well as natural teeth.
  • It's probably best to use activated charcoal powder or charcoal toothpaste once in a while, rather than every day.
  • Use activated charcoal products carefully until more research is done on its long-term effects.

So it hasn't been definitively proven that black charcoal will whiten your teeth. Even so, some scientific evidence and traditional wisdom suggest that there could be an advantage to using a carbon infused toothbrush over a regular one.

Electric toothbrush heads with charcoal bristles

Maybe you want to try out an activated charcoal toothbrush but are deeply in love with your current electric brush and don't want to give it up. If that sounds familiar, you are in luck.

An Oral-B charcoal head

Well, only if you have an Oral-B.

They offer charcoal bristle replacement heads that are compatible with almost all models (the main exception being their latest iO series) so you can add activated carbon into your tooth cleaning routine without even changing your brush. You can find other brands of black charcoal heads for Oral-B electric brushes that are cheaper, but we will warn you that you may void the warranty on your toothbrush base by using an off-brand head.

Unfortunately, Phillips Sonicare doesn't include a charcoal head, and there aren't currently any off-brand ones on the market. So, Sonicare users are out of luck here, but that doesn't mean there aren't any sonic brush options out there.


The Burst sonic toothbrush has become popular on social media thanks to its sleek design and subscription service. The Burst toothbrush stands out to us because it has charcoal-infused bristles. We have a full Burst charcoal toothbrush review that you are encouraged to check out, but for now we'll give you a quick summary.

The main features of Burst are:

  • 33,000 vibrations per minute
  • Black charcoal-infused bristles
  • 3 power settings
  • 4 weeks of battery life per charge
  • Replacement brush head every 90 days

Although it does not have the pressure sensors or app connectivity of high-end brushes like Sonicare DiamondClean or Oral-B iO, it is significantly cheaper for the base brush and replacement heads. It also outperforms more economical options from those brands, and as far as charcoal-infused toothbrushes go, it's perhaps the most powerful currently on the market. Burst is currently offering a 10% discount on the brush if you use code BURST10 at checkout.


Although there isn't definitive scientific proof that activated charcoal can whiten your teeth, it does have an established history as a purifying substance and traditional use in dental hygiene. But while we wait for more studies to be conducted, it won't hurt to try out this natural alternative to chemical whitening agents.

Between standard, electric, and natural vegan options, there are brushes available to fit into any routine. If you're interested, talk to your dentist, try an activated charcoal toothbrush, and see how it works for you!


How do charcoal toothbrushes work?

Activated charcoal in incredibly porous, which allows it to absorb different substances very effectively on a microscopic level. For instance, it is ingested to absorb poison in the stomach. Although it is not completely confirmed by science, this porousness can theoretically absorb staining from teeth. Charcoal's abrasive qualities also contribute to this effect.

Is there a difference in how to use a charcoal toothbrush?

Charcoal bristle toothbrushes work exactly the same way as your everyday toothbrush. That said, you may want to brush carefully at first. Activated charcoal is abrasive and could cause irritation.

Should I ask my dentist before using activated charcoal?

Activated charcoal has been used for years in various ways. If you are using a known activated charcoal toothbrush as directed, there should be no danger. Ask your dentist about specific concerns.
