Activated Charcoal Whitening Toothpaste

Being the greenie that I am, most of the conventional products in my bathroom were replaced long ago with their eco-friendly alternatives. So it was only a matter of time before I started delving into how I could actually make a lot of these products myself; toothpaste seemed a great place to start. After trawling the web, I became aware that toothpaste is really just for cosmetic purposes. We essentially use toothpaste to stop our mouths from tasting like, well, mouths. By making your own, your gob will still taste wonderfully of peppermint, your teeth will be just as squeaky clean, you’ll avoid harmful ingredients (such as fluoride and triclosan) and you’ll be doing your bit to conserve Earth’s limited resources. You’ll also save yourself some cash… and who doesn’t want that?

Though you can make a super simple zero waste toothpaste by combining baking soda, coconut oil and peppermint essential oil, this recipe includes bentonite clay and activated charcoal as a natural whitener. I’m lucky enough to have a wonderful eco store nearby where I can purchase the natural ingredients required to bring this recipe to life, a company that I know is committed to reduce waste, toxins and harm to the planet. These guys also have a fantastic online store.

The toothpaste turned out to be a thick consistency that could be easily applied to my toothbrush and that foamed up quite well. Despite having black teeth while brushing, the charcoal washes right off to reveal your newly shining pearly whites!

Here are the steps to prepare this stellar toothpaste that is completely natural, vegan and perfectly minty.



  • 1/2 cup bentonite clay
  • 1 tbsp bicarb soda
  • 4 tbsp coconut oil
  • 1 tsp activated charcoal
  • 15 drops peppermint essential oil


  1. Mix the ingredients with a wooden spoon in a small bowl.
  2. Transfer the mixture to a small glass jar and store in a bathroom cupboard.
  3. Use a small spatula, paddle pop stick or reused ice-cream spoon to pick up the toothpaste and put onto your toothbrush.

If you don’t have one already, a bamboo toothbrush is a great complement to your zero waste toothpaste. In Australia, more than 30 million toothbrushes are disposed of each year. As most of these toothbrushes are made from non-biodegradable materials like plastic, nylon and rubber, they sit in landfill and do not easily break down.  Every little bit counts; you can make a difference!
