If you leave whitening toothpaste on your teeth will it work the same as whitening strips????
Ghetto teeth whitening?
No, whitening toothpaste works by removing stains from the teeth due to the increased amount of abbrasives in the paste. They don't actually whiten the teeth, they just remove stain better than other toothpastes. Whitening strips work via a peroxide/carbamide peroxide affect.
