Cheap tooth whitener
I heard about a method to whiten your teeth without spending all that money on expensive tooth whiteners. It's simple-just brush your teeth with a mixture of baking soda and hydrogen peroxide. You have to make up the mixture just before you use it. I just put a small bit of soda in the palm of my hand, add a few drops of peroxide and brush away. It takes away all the coffer/tea stains.
