5. Homemade toothpaste with hydrogen peroxide and baking soda
One way to whiten teeth with hydrogen peroxide is to make a paste combined with baking soda.
This mixture eliminates bacteria and germs present in the mouth, while whitening teeth and freshens breath.
Mix 2 tablespoons of baking soda and 1 tablespoon of hydrogen peroxide solution (it should not exceed 3%), until you get a thick paste. If the paste is very thick, you can add a little more hydrogen peroxide to thin it to the desired consistency.
You can keep the toothpaste for a month in a tightly closed container.
We will not lie to you, the taste of this combination is bitter. We recommend adding 2 drops of peppermint, aromatic oils or finely chopped strawberries to enhance the flavor.
