- Baking Soda. Be careful what brand you pick Arm & Hammer tests on animals. Bob's Redmill does not.
- Pure peppermint oil.
- Salt (optional)
- Filtered/purified water
Put the baking soda in a bowl. If you're adding salt, use a pinch now. Slowly add water until you get a crumbly, sandy consistency going. Then add peppermint oil. Some people like a lot of peppermint (we use a lot), but you may want to go easy, depending on how much of a kick you want your toothpaste to have. Less is better at first - you can always add more. Taste test as you go along. Add more water until you get a good paste. You don't want it too runny or too dry.
Some homemade toothpaste recipes call for glycerin. This is an unnecessary expense, in my opinion.
Keep a little spoon near the jar or bottle you store your toothpaste in, to smear a dab on your toothbrush. Use it as you would any commercial toothpaste. We've been using this recipe for two years,and we wouldn't go back to using the store-bought stuff even if they stopped testing on animals!
