Well, I went to the store to get some and I saw another one for Arm & Hammer called Advance White Sensitive. It provides sensitivity relief plus whitening. Since it was cheaper than the Sensodyne, I figured I might as well get it since I am a broke college student

Anywhoo, now I worry that I may be hurting my teeth. Doesn't whitening have the potential to CAUSE tooth sensitivity? Should I be staying away from whitening tooth paste.
Does any of you currently use whitening toothpaste with your braces? Any noticeable effect, negative or positive?
Thanks
