Zero Waste Toothpaste

This is by far my favorite zero waste/all natural “beauty” recipe! This recipe is simple, inexpensive, and has more benefits than store-bought toothpaste.


Time: 5 minutes

Difficulty: Easy


  • 6 Tbsp coconut oil (1/3 cup)
  • 4 Tbsp baking soda (1/4 cup)
  • 25 drops peppermint essential oil
  • 2 pinches sea salt



  1. Melt coconut oil in a double boiler until slightly melted.
    • I just take my glass mason jar where I am going to store my toothpaste and put it in an inch of water in a pot on low. Don’t have to dirty another dish!
  2. Combine all ingredients and mix until the mixture resembles a creamy paste.

To Use

With a spoon, wooden popsicle stick, or just your toothbrush (my preferred method), put some of the toothpaste on your toothbrush and brush those ivory teeth. This toothpaste does not foam like a normal toothpaste. The coconut oil will melt in your mouth and you essentially have a gritty oil. Do not be deterred! This toothpaste still works wonders.

I use about a quarter sized amount and brush as normal. Because it gets melty I keep my mouth more closed than I used to. At first, I would drool like a fool.

I use a bamboo toothbrush too and love it! I love the brush with bamboo brand. They have an organic bamboo handle, plant-based bristles (that feel like regular bristles), and completely plant-based compostable packaging! Buy them here.

Cost Comparison

$2.35 (coconut oil) + $0.13 (baking soda) + $0.48 (peppermint essential oil) + $0.06 (sea salt) = $3.02

3 bucks compared to 5 for a brand toothpaste full of chemicals?! I’ll take it. Now this is the cost per batch of toothpaste which will last the same amount of time (maybe a week less) than store bought.

There is an upfront cost to making your own products. For example, I have to fork out $6.00 for peppermint essential oil up front. But it will last me many (about 12) batches of toothpaste.

Now the real kicker here is the peace (or should I say price) of mind I gain when making my own toothpaste. I can make this will essentially no waste!


So a little about the ingredients. I’m not an expert about store bought toothpaste but I do know it is full of chemicals (some are probably are okay but…). I know exactly what’s in my toothpaste. And it’s easy to make!

Coconut oil is antibacterial (and coconut oil is a granola guru’s bread and butter as you’ll see) so it helps fight any nasty bacteria. After I switched to making my own toothpaste I noticed that I had better smelling breath. Really!

Baking soda has amazing whitening properties. Even my dental hygienist recommended buying a baking soda based toothpaste. I drink copious amounts of tea so my teeth gain stain. So, not only does stain looked unpleasant, but it also is sticky which means all those nasty bacteria and plaque stay on your teeth which can lead to cavities. The baking soda is gritty which will break down that stain and whiten your teeth at the same time! Win, win.

Peppermint essential oil tastes great and will leave you smelling minty fresh. Essential oil can be swallowed when it is diluted properly. Again not an expert here. For kids, if you are afraid about them swallowing it, you can just omit the essential oil altogether! Or just lessen the amount that you add. The rest of the ingredients you definitely can consume.

Pinches of salt you say? Adding salt also adds a bit of grit to help break down stain, plaque, and particles. Like in baking you add salt to help make it sweeter. Same concept? Definitely, but only if you don’t add too much. You can experiment to see how much you like. At one point I added like 2 teaspoons of salt… Yeah, that was a salty batch.


This is shelf stable! If you add water to a DIY beauty project then it won’t be shelf stable. Then you get this thing called mold (ew!). Adding water is okay but then you have to keep in the fridge.

It’s ready to use right away! This amount lasts me about 2 months.

Coconut oil melts pretty easily in a hot apartment so I mix it with my toothbrush beforehand if the baking soda starts to settle.

Another zero waste toothpaste option is tooth powder. Has anyone used a tooth powder before and have experience to share? I know many zero wasters buy their tooth powder in bulk too. It sounds just as effective and natural. Thoughts?

Happy Making-
