What Is Charcoal Toothpaste?-Read Before Using


When you hear about natural alternatives for whitening your teeth, you are sure to learn about charcoal toothpaste. But hold up! As a dental hygienist, I want to inform you of the good, the bad and the ugly when it comes to these products.

So, what is charcoal toothpaste? I will explain everything you need to know. Please read this before using. There are certain safety factors you need to be aware of and important side effects of this product to consider.

Charcoal toothpaste can have an important place in your arsenal of oral health products but you must be well-informed when choosing the right product.

How Do They Work?

A toothpaste that contains activated charcoal can help to remove surface stains on your teeth. The reason for this is due to its abrasiveness. It can also help to absorb surface stains to a certain degree. However, charcoal toothpastes have not shown significant evidence in their ability to remove stains below the surface of the enamel.

For this reason, charcoal toothpastes cannot be considered whitening toothpastes. In order for a toothpaste to be considered a whitening toothpaste, it needs to not only work on the outside surface stains but on those below the enamel as well.


Activated charcoal is the main ingredient in charcoal toothpastes. It is a fine black powder created from a mixture of bone char, peat, petroleum coke, coconut shells, coal, sawdust and olive pits.

It should not be confused with charcoal briquettes for grilling. These briquettes have not been “activated” and are considered toxic to humans.

What makes the charcoal activated is a process that heats the charcoal to a very high temperature. This process changes the internal structure of the charcoal by increasing its surface areas and reducing the size of its pores.

Activated charcoal works by trapping chemicals and toxins. There is a negative electrical charge created that works by attracting the positive charge of molecules from gases and toxins.

This has been shown to work in the gut and it is why it is used in cases of poisoning. Activated charcoal has been used for this purpose since the early 1800s. It has also been used to treat overdoses from prescription drugs such as acetaminophen, sedatives and aspirin.

There are many other uses for activated charcoal ranging from improving kidney function, gas reduction, cholesterol reduction and water filtration. However, there are no studies to support the claim of teeth whitening or improvement in oral hygiene.

Some May Cause More Harm Than Good

Dangers of charcoal toothpaste

While using charcoal toothpaste may make your pearly whites appear whiter initially, some versions may make them appear more yellow in the long run.

The reason for this is that their abrasiveness will wear away the outer enamel over time. Once the enamel is worn away, you can never get it back. When it’s gone, it’s gone. This allows for the underlying tooth material called dentin to shine through.

If the outer enamel is worn thin you will see more dentin (a brownish-yellow colored material) and it will make your teeth appear darker. There are other reasons some charcoal toothpastes should be avoided. With a loss of enamel, you may have increased tooth sensitivity and be more susceptible to dental decay.

Not Accepted By the ADA

The American Dental Association has not given charcoal toothpastes the thumbs up. Learn what is said about charcoal toothpastes by the Journal of the American Dental Association.
It is recommended that dental professionals instruct their patients to be cautious when using charcoal-based toothpastes due to their unproven claims of efficacy and safety.

Results from this review showed insufficient laboratory and clinical data to establish conclusive evidence showing safety and effectiveness of charcoal-based toothpaste.

The Best Charcoal Toothpaste

If you decide you would like to try a charcoal toothpaste, I highly encourage you to purchase a product that will not be harsh or abrasive on your enamel. But how do you know which ones to choose and which ones to avoid? There is a tool used to determine the abrasiveness of these products.

This is a scale used for oral health care products used by dental professionals. This scale is called the RDA scale and it stands for Relative Dentin Abrasivity. When choosing a toothpaste product, you want a product with a low RDA score which means it is safe for everyday use and will not cause the enamel to wear away.

Although enamel is the hardest substance in the human body, it can still be worn away with daily use of an abrasive toothpaste. Once the enamel is worn away, it leaves the sensitive dentin exposed. This increases tooth sensitivity and puts you at greater risk for cavities. There is one product containing activated charcoal with a low RDA. It is Tom’s of Maine Peppermint Activated Charcoal Toothpaste.

Tom's of Maine activated charcoal toothpaste

This product is the gentlest charcoal toothpaste based on RDA testing among leading natural brands. You can use this product for twice daily brushing the same way you would use a non-charcoal toothpaste and it is considered safe on enamel for everyday use.

Tom’s of Maine Activated Charcoal Peppermint Toothpaste is the recommended choice of dental professionals for those patients seeking a less abrasive charcoal product. You can learn about additional benefits of using products from the Tom’s of Maine company in this video:

To understand more about the RDA of toothpastes The American Dental Association (ADA) gives their findings. They explain that all toothpastes are rated on a scale with a standard being 100. Toothpastes are considered relatively safe for dentin and enamel if they are rated less than 2.5 times the standard value (250). There is also a very informative article from RDH (Registered Dental Hygienist) Magazine that explains the importance of the RDA scale when choosing a safe and effective toothpaste. Please read this article to further understand this concept.

    I was given a tube of charcoal toothpaste and was curious if it would actually work. Thank you for sharing this review, from what you are saying it will possibly cause more harm than good.  I think I will wait until there is a little more known about charcoal toothpaste.  Thank you for the information-it is very helpful!

      It is wise to be cautious when using these products.  So many of the brands sold online and in stores are damaging to the enamel.  This is mostly due to their abrasiveness.  Please use a charcoal product which has low abrasiveness such as the one mentioned in this article.



  2. Marketa

    Hi and thanks for your informative and timely article about charcoal toothpaste.  I’ve been using a charcoal toothpaste for some time now and like you have stated in your article, I am experiencing some yellowing of my teeth.  I thought that this meant I needed to use more of the product but from what you say, it seems I need to give it a rest.

    1. Michelle


      So many of the charcoal toothpastes can contain abrasive particles that can damage the enamel on teeth over time.  Be sure to use a product that is low on the Relative Abrasivity Scale (RDA) as measured by dental professionals.  Try Tom’s of Maine Activated Charcoal Toothpaste combined with the gentleness of an electric toothbrush.  If you are looking to whiten your teeth, you can try these recommended treatments mentioned in the article ‘The Best Teeth Whitening Products- Dental Hygienist’s Top 3‘.

    I really don’t have any issues with the color of my teeth.  I’m 70 years old and at my age, I’m not sure that it really matters anymore.

    My wife and I actually use Sensodyne Pronamel and floss regularly and my Dentist/Hygienist seems to be pretty happy when we go in for our regular cleaning. 

    To me. I think as long as one does these every day and gets a good cleaning, all should be good and really… the alternative isn’t appealing at all.

    I do have one question though.  Do you think that maybe there might be too much hype over the “whiter teeth” craze?  It just seems to me that the world is being told that they are not their best if they don’t have whiter teeth.  What do you think?


    1. Michelle


      I am so happy you have commented on the article ‘What Is Charcoal Toothpaste? Read Before Using’.  I whole heartedly agree with you that too much emphasis is being put on the whiteness of our teeth.  More importantly, we should be concerned about the health of our teeth and not the color.  There is a misconception that if our teeth are white that they must be healthy.  This is not always the case.  A person could have whitened their teeth but at the same time have issues with decay (cavities) and/or gum disease.  Proper diet, nutrition and good oral hygiene habits are much more important than the color of your teeth!
