DIY: A Nontoxic Way To Whiten Your Teeth

Bleaching our teeth white is not cool. We are putting so many harmful chemicals on our teeth and in our mouths that seep through to the gums, tongue, and rest of the body that it is scary. Plus whitening your teeth can cost you hundreds of dollars or more. I tried bleaching my teeth once before I knew about the natural alternatives, and it really hurt my teeth and gums. It was not worth me going through that pain.

Now I use baking soda and bentonite clay to whiten my teeth periodically. Both substances are naturally provided by Earth and have health benefits. I alternate between the two, as the baking soda can be abrasive on my teeth and gums. If I start to feel even a tiny sting, I switch to bentonite clay.

Baking Soda

Keep a jar full of it in your bathroom. Spoon 1/2 tsp. onto your toothbrush after brushing your teeth. Brush in gentle circular motions, buffing your teeth as if you were going through a carwash. You may want to do this every day for 14 days until your teeth are whiter. Once your teeth are white, stop brushing them with baking soda for a while, until you feel like doing another polish.

Bentonite Clay

Keep a jar full of it in your bathroom. Spoon 1/2 tsp. of it onto your toothbrush after brushing your teeth. Brush in a gentle circular motion on your teeth, just like you do with the baking soda. Do it for a few minutes until you feel like everything is squeaky clean.

Natural Tooth Whitener


  • 2 tablespoons of baking soda
  • 2 tablespoons of bentonite clay

Preparation + Use

Mix them together and store in your bathroom.

Put 1/2 tsp. on your toothbrush and use it to scrub your teeth. This yields 4 Tbsp. of powder, enough for 12 days if you're using 1/2 tsp. twice a day.
