Put a tiny bit of toothpaste into a small cup, mix in one teaspoon baking soda plus one teaspoon of hydrogen peroxide, and half a teaspoon water. Thoroughly mix then brush your teeth for two minutes. Remember to do it once a week for pearly whites :)
Teeth Whitening Home Remedy. When I first saw this I thought its gonna have a nasty taste and my mouth is gonna fizz from the peroxide and baking soda. To my surprise it actually made my teeth whiter without leaving a nasty taste in my mouth.
