Benefits of bentonite for oral health
Bentonite
Bentonite clay (so named because a great deal of it was first discovered in Fort Benton, USA) is so widely used, it’s hard not to take it for granted. It forms the base of medicines, skincare products and of course in Truthpaste Original and Truthpaste Charcoal.
The clay is formed naturally between rocks when volcanic ash and water settle. The result is a spongy, mineralised and highly absorbent clay that is rich in antibacterial and anti-inflammatory properties.
New studies are emerging on the many benefits of bentonite clay. Research is currently being undertaken into how it could be used for treating serious ailments like cancer, immune deficiency and blood clotting.
Bentonite Clay for Skin
Bentonite forms the base of a huge number of skincare products. It’s usual to find it in facemasks and lotions but is also used to treat conditions like dermatitis, acne and nappy rash.
Given its natural absorbance, it attracts dirt and skin impurities, whilst the anti-inflammatory alkaline properties help to soothe sore and irritated skin.
Bentonite Clay for teeth
So why do so many manufacturers use bentonite in toothpaste?
There are several benefits, some of which we’ve already covered
-
Bentonite absorbs toxins - It reacts with water (and saliva) to attract the dirt and particles that build up in the mouth. After eating, food particles can get lodged in teeth and gums where they attract harmful bacteria. Bentonite acts as a kind of sponge. It has a negative electrical charge, whereas bacteria and germs have a positive electrical charge. So the clay attracts the particles and holds them, leaving your mouth feeling cleansed and clean!
-
Bentonite clay is Alkaline -A healthy pH balance is often overlooked as an important part of oral care. However, it’s vitally important to the health of teeth and gums, and even keeping your breath fresh! Sugary and fatty foods are high in acid. Bentonite clay helps to neutralise that acid and restore a natural balance to your mouth.
-
Bentonite clay is rich in minerals - The type and level of those minerals will vary depending on where the clay is sourced. Typically you can expect to find calcium, magnesium and silica. Where bacteria can wear down tooth enamel, bentonite is thought to be useful in strengthening and even possibly rebuilding enamel. Further studies are needed to determine the full extent of the benefits to using bentonite for remineralisation.
-
Bentonite clay is a natural tooth polisher - Bentonite is a very fine powder that polishes enamel without being harmfully abrasive. The particles gently polish the teeth which is what leaves them feeling super clean.
- Bentonite clay can naturally whiten teeth. With its polishing and absorbent properties, bentonite is a safe and efficient way to help remove surface stains on teeth.
Bentonite compared to traditional toothpaste ingredients
A 2011 study looked into 26 different toothpastes to compare the abrasion, polishing and stain removal characteristics of the different mineral bases. Ingredients included hydrated silica, calcium carbonate, sodium bicarbonate, dicalcium phosphate, pentasodium triphosphate, kaolin clay, and bentonite clay.
The study looked at the Relative Dentin Abraisivity (RDA) and the Pellicle Cleaning Ratio (PCR) - or how abraisive the toothpaste was and how well it cleaned or whitened teeth.
Each toothpaste was given a Cleaning Efficiency Index (CEI). A toothpaste with high whitening ability with low abraisivity would score high on the index, compared to a toothpaste with high abraisivity but low cleaning effeciency.
Generally, the more abraisive the toothpaste, the better the cleaning efficiency, except with toothpastes containing the mineral clays bentonite or kaolin.
Toothpastes with bentonite scored a higher cleaning efficiency but with lower abrasivity, compared to those with hydrated silica and traditional toothpaste abrasive ingredients.
Bentonite in Truthpaste
Our toothpastes have a bentonite clay base. Our clay comes from Wyoming, USA and is part of the reason we get so much lovely feedback about the really clean and fresh feeling you get from brushing.
We feel that it’s not only important to know what ingredients go into your toothpaste, but how they work to benefit your whole mouth health as well.

from 1104 reviewsI 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!
Very pleased with my order, love both mouthwash and 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
