What is the best toothpaste for whitening and gentleness on the enamel?
I think the Arm&Hammer stuff is best for whitening but it just feels harsh. Colgate and Aquafresh feel gentle on the old pearly whites but don't do much for the brightness.
Is there a happy medium. Perhaps using Colgate for 5 days and Arm&Hammer for 2 per week?
I drive an automatic 'cause I'm too cool to change gears.
