Excellent Results
Arm & Hammer Whitening Booster is a fantastic product. I brush with it twice a day and my teeth are absolutely brilliant, having gone from a dull off-white. I do have sensitive teeth, so initially I was worried about the effects, but on top of my sensitive teeth toothpaste it's just fine and I've experienced no extra discomfort. My teeth were healthy and unstained to begin with, I do not know how this will work on stained teeth. I get compliments on my smile all the time now!
