Question: how to make your teeth whiter with stuff at home?
Answer: Another way to use hydrogen peroxide is by mixing it with baking soda to make a toothpaste. Combine 2 teaspoons of hydrogen peroxide with 1 teaspoon of baking soda and gently brush your teeth with the mixture. Limit the use of this homemade paste to a few times per week, as overuse can erode your tooth enamel.
