Easy 4-ingredient natural homemade toothpaste

toothpaste with text

For months now, I’ve been cleaning my teeth with a combination of coconut oil, salt and baking soda.


Conventional store-bought toothpaste actually contains a bunch of nasties I’d rather not put anywhere near my mouth. Like sodium lauryl sulfate, which is also found in engine degreasers, floor cleaners and car wash soaps. No thanks.

Instead, I’ve come up with a natural homemade toothpaste recipe that requires only four ingredients, most of which you probably already have in your pantry. Then it’s just a matter of mixing them all together. Done.

Admittedly, it is a bit strange at first. But you quickly grow accustomed to the salty taste and no-foam texture.

Then you start to notice how clean your teeth feel. The gentle grittiness of the salt (which has antibacterial properties) and bicarbonate soda removes plaque while the coconut oil leaves your tooth enamel feeling silky smooth and your gums nourished.

I still do use store-bought toothpaste occasionally, especially when travelling. But I’ll never go back to chemical-laden supermarket brands. (Unconvinced? Read this article by a dentist, detailing all the nasties in conventional toothpaste, and why they’re unnecessary.)

Instead, if I buy toothpaste, I stick to all-natural brands. Health food stores usually offer several good options and some supermarkets now stock natural toothpastes, too. So if making your own doesn’t float your boat, at least consider swapping to a more natural brand.

Of course, the benefit of making your own toothpaste is that you know exactly what’s in it. No need to decipher complicated ingredient lists or research brands to ensure they truly are ethical.

Plus, you cut down on packaging. And when you run out, you can quickly whip up more without ever having to leave your house.

While we’re on the topic, a quick word about toothbrushes.

Over 4.7 billion plastic toothbrushes are produced worldwide every year. Most end up in landfill. Or polluting our oceans.

The solution is dead simple: switch from single-use toothbrushes to biodegradable bamboo brushes, like the Environmental Toothbrush or Brush With Bamboo.

Sadly, compostable toothbrushes aren’t so easy to find here in Spain. (Correct me if I’m wrong, Spaniards?) So for now I’m using an EkoTec plastic toothbrush with replaceable heads.


Now to the recipe.

Easy homemade toothpaste


5 tablespoons coconut oil
3 tablespoons bicarbonate soda
1 teaspoon sea salt or pink Himalayan salt
10 drops essential oil **

** My favourite essential oil is peppermint but you can get creative. Cinnamon, clove, tea tree, lemon and rosemary all work, too.


Throw everything together into a small bowl and mix well. If you’re in a particularly cold area, you may need to warm the coconut oil a little first to soften it.

Store in an airtight container.

To use, just spread a small amount on your toothbrush as you normally would. You may need to use a spoon if you’re in a cold area, as the coconut oil will harden.

Brush as usual.

    Thank you, Koren. I’m happy not to have that load of SLS-laden foam to spit out! I felt so self-reliant, mixing up a toothpaste from ingredients I already had in my kitchen. I have no appropriate essential oils, so I added a pinch each of ground cinnamon and nutmeg, and a tiny touch of ground cloves. It didn’t exactly taste like chai tea, but I may stir in some more next time. Do you think that it’s safe to add those finely ground spices?

      Hey Bronwen, cool idea! I guess my only concern would be that the spices might be abrasive on your teeth and damage the tooth enamel. Maybe just keep an eye on it and see how it goes?
