Hi friends.Don’t believe that you will see changes in a week as advertised.I have been using this product for 3
months and I have seen some visible change in the color of my teeth. I drink lots of Tea so this toothpaste helped me to regain some whiteness which I lost. Even though the price is higher its worth to spend. But believe me its a slow process and you wont find any difference if u check everyday.may a couple of months will make a differnce
worth noticeable
