Whiten your teeth

Simply combining hydrogen peroxide and baking soda can give you a brighter smile. Here are some tips from Colgate:

• Use less baking soda than hydrogen peroxide, and make sure your paste isn’t gritty.
• Combine about two tablespoons of hydrogen peroxide with one tablespoon of baking soda.
• Stir into a paste and start brushing.
• Let the paste stand about a minute and then rinse.
