Is brushing your teeth a chemical change?

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!


Are teeth chemical or mechanical digestion?

Teeth are involved in mechanical digestion. They physically break down food by crushing, grinding, and cutting it into smaller pieces, making it easier for enzymes in the digestive system to access and break down nutrients.

Do teeth cause a chemical reaction to take place?

Teeth themselves do not cause a chemical reaction. However, when food comes into contact with teeth, the process of digestion begins with enzymes in saliva breaking down the food molecules into smaller components. This can be considered a chemical reaction in the context of digestion.


Is burning food a physical change?
