you could purchase the Arm & Hammer baking soda at your local grocery store...
What you do is place a sprinkle of baking soda with your toothpaste and brush brush brush.... do this a whole week and you would see results... I feel though that you should wait a while after doing this a whole week.. you don't want to lose your enamel..so wait a while after doing again to be on the safe side...
There you go... a cheap way to whiten your teeth.. I have yet to try out the Crest white strips.. but I heard reviews and they weren't all that great...:( .. we'll see.. but try this one out..works wonders!
