Have you heard of dental powder? It's basically tooth paste without the 'paste'. It's a great way to clean your teeth without a ton of chemicals or ingredients, and it eliminates the need for nonrecyclable plastic tubing (which is what regular toothpaste is packaged in). You can try making your own, or get a pre-made one. @wholemade.co makes a chemical free dental powder. Check out her Etsy page for details.
