Laura,
Three stars sounds like a bad review, but its only because of the taste that this toothpaste leaves behind. I tried it several times and it certainly does work - its great at cleaning teeth - but I couldnt get past the aftertaste. And its not just the baking soda, because in the past I have used just baking soda. Just something about the taste. Arm and Hammer is a great brand, and I use their stuff all the time. Really wanted to like this.
