Colgate Whitening Fluoride Toothpaste, Baking Soda & Peroxide Whitening (Brisk Mint Paste)- 8.2 oz

I bought it two weeks ago, I am using it once per day.

My teeth are brighter and whiter, and seem cleaner.

But since yesterday, I have felt more sensitive to cold food and water ...

I think I'm gonna combine with another toothpaste for sensitive tooth.
