I have always used Colgate toothpaste, ever since childhood when recommended by the dentist. I started having issues with sensitivity to cold drinks about a year ago, and had to try a different product (Sensodyne) but I didn't care for it. I thought I would just have to deal with it until I found out that Colgate had developed a new product to not only help sensitivity, but also whitens your teeth at the same time. I wasn't a bit skeptical, Colgate has never let me down. The flavor is amazing, unlike other "so called" toothpastes for sensitive teeth. It has helped me tremendously, does a great job of cleaning my teeth ( of course ) and whitening them. It leaves my breathe fresh, as well. It has a nice minty flavor and no gritty abrasives. The cost is much lower than Sensodyne and you can buy it in a three pack, which is a great deal. Colgate always comes through! It works and I recommend it. You have nothing to lose but much to gain.
