I'm not really faithful to any particular toothpaste, so I most likely had a coupon for this. Anyway, I just ran out, so I thought I'd write a review. I purchased the Clean Mint flavor in a 6 oz. tube. This toothpaste boasts the ADA seal of approval which is always a good sign. It also claims to fight cavities, plaque, tartar, and gingivitis, plus it whitens teeth and freshens breath. Wow! If only it would wash and wax my truck. I don't notice any difference with this toothpaste - my oral health seems to be exactly the same as it was. Also, I don't believe that any toothpaste is in contact with your teeth long enough to whiten them significantly, but if it buffs off surface stains (coffee, tea, cranberry juice, etc.) then it's worth using. This toothpaste seems to do a good enough job of that, plus it has a pleasant taste. I also like that it is slightly gritty, like the stuff they polish your teeth with at the dentist's office. So, if you use this with an electric toothbrush (I recommend Rotadent, but I imagine the Crest Spin Brush or something similar would work just as well), it feels like you are getting a professional cleaning.
