Okay, I have looked up whitening methods and stuff here on yahoo answers, and I have figured out that baking soda seems to work... But now I am seeing a lot of answers saying it is bad for your teeth cause its bad for your enamel. So I was wondering if Arm and Hammer toothpaste works (whitening) I heard it has a SAFE amount of baking soda that does not harm... is this true? Or is there a TOOTHPASTE, not method, that works better??? Thank you so much!!!!
