how do i whiten teeth at home using products i already have? i heard baking soda works but it did not work well.
--------------------
Use 2 parts water to 1 part hydrogen peroxide. Just swish it around in your mouth for about 60 seconds, and spit it out. Try not to swallow any (though if you did it would not kill you). Do this once a day after you brush and you should see a difference in about a week or less. Then just repeat as needed.
