Bentonite clay continues to make waves in the natural oral care world, and for good reason. Renowned for its detoxifying properties and mineral-rich composition, this natural wonder is not only effective but also incredibly gentle on your teeth. But what does science say about its cleaning efficiency and abrasiveness? Let's dive into the research to see why bentonite is becoming a favorite for those seeking a cleaner, healthier smile.
The Science Behind Bentonite's Cleaning Efficiency
One of the standout features of bentonite clay is its impressive cleaning efficiency. Studies have shown that bentonite scores remarkably high when it comes to removing plaque and surface stains. This is largely due to its unique ability to absorb impurities and toxins, making it highly effective in drawing out and capturing the debris that can accumulate on our teeth.
In the world of oral care, the Pellicle Cleaning Ratio (PCR) is a key measure used to determine how effectively a toothpaste can remove stains and plaque from teeth. Generally, the higher the PCR, the more abrasive the toothpaste tends to be, as it needs to scrub away debris. However, bentonite clay is unique. Despite its high PCR, indicating excellent cleaning ability, it has a low Relative Dentin Abrasivity (RDA) score, meaning it cleans thoroughly without being harsh on enamel. This combination gives bentonite a high Cleaning Efficiency Index (CEI), setting it apart from many conventional toothpastes.
Gentle Yet Effective: Low Abrasiveness Confirmed
While bentonite clay’s cleaning power is impressive, what about its impact on enamel? It’s natural to wonder if something so effective might be too harsh, but here’s where bentonite truly shines. Research shows that bentonite has a low abrasiveness score, making it safe for daily use without wearing down enamel.
One of the ways scientists measure abrasiveness is by using the Mohs hardness scale, which ranks materials based on their ability to scratch one another. Bentonite clay scores between 1.5 and 2 on the Mohs hardness scale, which is even lower than a human fingernail (which ranks around 2.5). This means that while it’s tough on plaque and stains, it’s incredibly gentle on the delicate enamel that protects our teeth.
Studies Confirm Bentonite's Superior Performance
Further supporting its use in oral care, studies like the one by Putt et al. (2011) have demonstrated that bentonite clay toothpaste can deliver superior results compared to many conventional toothpastes. It effectively cleans without causing damage, thanks to its lower Relative Dentin Abrasivity (RDA) score. This low abrasiveness is a major factor in why bentonite is favored by those looking to maintain their enamel while achieving a deep clean.
What’s more, bentonite doesn’t just clean—it also promotes overall oral health. Its mineral content helps to neutralize bacteria and reduce inflammation, making it a holistic solution for a healthy mouth.
Why Choose Bentonite for Your Oral Care Routine?
If you're looking for an oral care product that offers both high efficiency and gentle care, bentonite clay is a top contender. Here's why it stands out:
-
High Cleaning Efficiency: Bentonite’s ability to absorb and remove impurities gives it a significant edge in cleaning power, making it a powerful tool in keeping your teeth plaque-free and bright.
-
Low Abrasiveness: Despite its effective cleaning action, bentonite is incredibly gentle on enamel. Its low score on the Mohs hardness scale and low RDA rating ensure that you can use it daily without fear of eroding your teeth.
-
Natural and Safe: Bentonite is a natural, chemical-free option that aligns with a holistic approach to oral care. It's free from the harsh additives often found in conventional toothpaste, making it a safer choice for you and your family.
Conclusion: Bentonite Clay—The Perfect Balance of Power and Gentleness
The research is clear: bentonite clay offers a unique combination of superior cleaning power with minimal abrasiveness. This makes it an ideal choice for those looking to maintain a healthy, bright smile without compromising their enamel.
By incorporating bentonite into your oral care routine, you’re not just choosing a product that cleans effectively; you’re also making a choice that supports long-term oral health. With its gentle yet effective action, bentonite clay is the perfect balance of power and care, helping you achieve a naturally clean and healthy smile every day.

Let customers speak for us
I suffer from gum disease and despite the effort I was putting into my daily dental hygiene routine this was not making a difference.
I liked the idea that there was a more natural alternative available in these products so thought I would give them a go.
Within a few days of use I’ve already noticed a significant difference in how my gums look / feel and as an added bonus these products seem to also reduce staining. Both the toothpaste and mouth wash taste great too.
A complete convert!!
Thank you
I suffer with a lot of neuralgia and toothache issues, I’ve found using this calms my mouth and lessens the pain and it’s all natural
Since I started using Truthpaste I won’t be going back to my old toothpaste! This one tastes fresh, I appreciate the natural ingredients and I can feel it doing me good. So happy I discovered Truthpaste.
Has been accepted and liked and used by sensory avoiding kid. After trying many toothpastes this is a hit. Like that it’s not a subscription and will last a while.
I use this alternatively with the Fennel toothpaste to manage colour as well as continue to heal tooth and gum sensitivity. A great natural product for the teeth.
since using this toothpaste twice a day for 2 weeks solid, my tooth and gum sensitivity has nearly gone, my gums have returned to normal, and their swelling and redness has gone...
The taste is great. Only been using a couple of weeks but my teeth and gums health have definitely improved.
I have used other toothpastes in jars in the past and was not terribly impressed so continued to use SLS-free toothpaste in tubes (recycled by a local Terracycle scheme). When this scheme stopped I needed to investigate using toothpaste in jars once again. Saw this advertised on Facebook and tried it a few weeks ago. I am very happy with the results so far (in combination with a new recyclable electric toothbrush). Teeth feel very clean, gums are not inflamed and mouth feels fresh. Will continue to keep using and will definitely recommend. The only issue I have is splash marks of toothpaste all over the floor in the bathroom. I have reduced the amount I use and try to keep my mouth closed during cleaning but it still happens! Having to clean my floor each day is a fair price to pay for using this great toothpaste!
What a fab discovery.
No more sensitive teeth or inflammed gums.
This stuff is the best! Great consistency that doesn't fall off your brush or slop about making a mess. Nice tingly taste and squeaky clean teeth. The 'wonky' price is even better value, but actually just a little dab is needed for a really good clean so a jar lasts for yonks. I'm a truly happy Truthpaste user. How's that for a tongue twister!
A good brush. Tough but good. The toothpaste is good also. I have been using it every other day to get used to it. It’s soothing on the gums and mouth. The mouth wash makes my mouth feel fresh and nice.
I’m a repeat customer. This toothpaste leaves my teeth feeling clean and my mouth fresh. I love that it’s natural and is in a jar. I travel frequently and haven’t found the jar to be a problem.
I started using my truth paste just over a week ago and have definitely noticed a difference, my gums are not so sore and bleeding as much as before, looking forward to seeing the difference after a few more weeks of use, I’m very hopeful of a vast improvement, great product!
This is such a great toothpaste- just what I have been waiting for. My teeth feel like I'm doing them good with this one and I don't miss the froth at all
