It's a physical action without toothpaste. Many toothpaste have inactive ingredients, and are only there to "taste good". Toothpaste with fluoride, baking soda, and other common dental ingredients will undergo small chemical changes when they come in contact with water (when baking soda in water come together it creates a chemical reaction). So in some respects it's both!
Without toothpaste it is a physical change. With toothpaste it is a chemical change. :)
Brushing teeth is not a chemical reaction;
Brushing is a mechanical process; but toothpaste is a chemical product.
It's never okay to use baking soda when brushing your teeth. Use toothpaste.
Up to six liters of water per minute can be wasted during teeth brushing. It is recommended to turn water off while someone is brushing their teeth in order to save water.
