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!
