When you make your own toothpaste you know what is in it. I have heard of make your own deodorant but never thought of making toothpaste. Although when I’ve been out of toothpaste I’ve used baking soda. I don’t know if that’s good for you or your teeth or not but that’s my backup so learning how to make real toothpaste is great. I just need to go shopping for this toothpaste recipe.
