Toothpaste brandedWhat if I told you that getting your teeth as beautiful as a movie star’s was actually pretty simple? Don’t believe me? It’s true! For instance, did you know that Julia Roberts uses baking soda to brush her teeth instead of toothpaste? If you don’t believe me, then check out this article.

The easiest way to get movie star pearly whites is by using that one simple ingredient… baking soda. It’s what people used to use before toothpaste, and it’s better for your teeth than store bought, chemical laden toothpaste.

I have been brushing my teeth without toothpaste for quite a while now. I used to think that store bought toothpaste was my only option and to be honest, that’s not an option I was happy with. I remember purchasing a brand of toothpaste that had what appeared to be tiny flakes of glitter in it. Glitter. In toothpaste. Why would I need glitter in my toothpaste?! Was it fairy dust meant to magically heal tooth ailments? Glitter. No thank you!

On top of the unsettling flecks of glitter in conventional toothpastes, there are also all sorts of other ingredients that just plain aren’t good to be putting into our mouths. In fact, the list of bad-for-you ingredients in toothpaste is so extensive, I’ll simply provide a link to an article that does a great job of reviewing them all. Click here to read about the bad-for-you ingredients in conventional toothpaste. Then I tried some of the “natural” toothpastes, and their ingredient list was just as long and just as unnatural as the big name brands. So I put a small dish of baking soda in my medicine cabinet and made the switch (if it’s good enough for Julia Roberts, it’s good enough for me).

The only problem…. I can’t get my husband to switch. He cannot stand the taste and smell of baking soda! Did you know that baking soda has a smell? I did not. But apparently there are people who find the taste and smell of baking soda utterly repulsive. So, I had to find a solution to satisfy both my need for good-for-you ingredients, and my husband’s need for minty fresh breath.

When we think of recipes, we often don’t think of recipes for toothpaste. Yet, besides food, toothpaste is what we put into our mouths most often, so why not try to find a healthy recipe for this as well? And then I found this homemade toothpaste recipe. Perfect… almost.

Homemade toothpaste recipe

The original recipe is a bit too long for me, so I narrowed it down to just 5 simple ingredients and have provided links to where you can find them online.



  1. Mix all the dry ingredients in a bowl until they are well blended.
  2. Add in a few drops of peppermint oil and a few teaspoons of coconut oil. Mix.
  3. Keep adding coconut oil and peppermint until you get a consistency and taste you are happy with.
  4. Put your toothpaste into a squeeze bottle. I like this one.

The bentonite clay is a swelling clay, so you will actually want the mixture to be a little runny at first because once it sits for a few hours it will thicken up. Leaving it a bit runny also helps to get the homemade toothpaste into the tube for easy dispensing on a daily basis. This recipe makes quite a big batch, I actually have some left over paste and powder that didn’t fit into the tube, so I think I will buy a bigger tube, or make half the recipe next time. Also, the paste ends up looking grey which was a bit weird for my husband, but its peppermint taste is just like regular toothpaste so he quickly got over the looks of it!

Why it works

Bentonite Clay

Bentonite clay contains trace minerals that can help build strong healthy teeth. It also has antibacterial properties that can help prevent tooth decay in the first place. Finally, bentonite clay is what’s known as a swelling clay and has long been used (both internally and externally) to draw out toxins, chemicals, and heavy metals from the body.

Calcium Magnesium Powder

Calcium and magnesium both help to build strong tooth enamel. We’re all pretty familiar with calcium being necessary for strong teeth and bones, but magnesium is required for calcium to properly be used to built those strong teeth. It’s also been coming to light lately that while most people get enough calcium, most people are not getting enough magnesium in their diets.

Baking Soda

You may already be familiar with baking soda’s powerful whitening effects, but it packs more than just a whitening punch. Baking soda also helps kill bacteria in your mouth by changing the pH level to kill the bacteria that causes plaque and bad breath.

Peppermint essential oil

Let’s face it… the main benefit of peppermint oil is being able to actually get my husband to use this homemade toothpaste instead of conventional toothpaste. But besides that, it is also an antiseptic. So really it’s a win-win for this recipe.

Coconut oil

Coconut oil has antibacterial properties that can help to eliminate plaque causing bacteria and prevent tooth decay. There’s even a whole movement over a process using coconut oil called “oil pulling” which is said to greatly improve tooth health.


Since writing this article, we’ve decided to cut out the coconut oil and stick to using the ingredients in their powdered form. We found that the coconut oil stuck to the bathroom sink and made a big mess. When I first made this recipe I was afraid that my husband would refuse using a tooth powder simply because it was so out of the ordinary, but it turns out that he’s totally fine with using a powder instead of a paste if it means easier bathroom cleanups. Seems to be a win-win situation!

We do still put the peppermint oil into the mix and the bentonite clay holds it so that the powder still tastes like peppermint :)
