I’m usually one to mock those sort of advertisments, believing they’ll never work, but after using this, I was able to eat ice-cream again pain free! My dentist gave me a sample of this toothpaste, and after using it for a few weeks I really noticed a difference in my teeth. Although the taste is a bit strange at first it is not unpleasant and it is easy to used to. If you have sensitive teeth you will know something like this is worth paying extra for.
