Question: how do you whiten your teeth with baking soda and hydrogen peroxide?
Answer: Mix a teaspoon of baking soda and a half teaspoon of hydrogen peroxide until the mixture turns into a toothpaste-like consistency. Use the mixture to brush your teeth. Let it sit for a minute or two before rinsing it off with water. Make sure to rinse well and use a three-percent solution hydrogen peroxide for safety.
