Colgate sensitive care is a very nice product. There was a time when I used to get a sensitive attack on my teeths while Drinking cold water or eating too much sweet and the pain used to continue for a while. Then I decided to go for a sensitive control toothpaste and I choose colgate sensitive care toothpaste over other products because I know colagate is a very geniune product and it proved me correct. When I started using colgate sensitive care this problem started reducing and now every thing is under control. So if you are suffering from sensitivity go for this product. As it is a product from colgate you dont have to worry about safety
