Crest 3D Whitestrips Sensitive At-Home Teeth Whitening Kit, 18 Treatments, Gently Removes 15 Years of Stains, Crest Whitestrips, Teeth Whitening Kit

The teeth became whiter indeed. Not reach the whiteness I was expected, but I have never whitened before. Will repeat after some 6 months.

The Crest 3D White Radiant Express Strips work really, really well. My teeth look whiter just after using it a few times and Im excited to see the results after the full 14 day treatment course. The strips are very easy to apply, they peel off easily and adhere to teeth without slipping. I didnt have any problem keeping them on my teeth for 1 hour, while I worked around the house. After I used them a couple days in a row, I did notice mild tooth sensitivity but it resolved as the day went on. I did take a break for a day from using the strips and it didnt happen since. I would recommend using these strips every other day or every few days if you have sensitive teeth to avoid sensitivity.

My teeth are not sensitive, so I didn't feel much pain. Moreover, I used the toothpaste for sensitive teeth during the whole period of using these strips.
Have ready to order them again.

I bought these as part of my quarterly upkeep regime - and used them as instructed. Within 2-3 uses, my teeth were visibly whiter compared to before, however, I will say that it takes time to get "celebrity white" teeth.

When I tried Crest Whitening it did wonders for my teeth. And I didn't believe that it would because I've used other products that said that they would do the same thing and they didn't. So I was quite skeptical. But, this one is one of the best I've ever used in my life. It was very sensitive to my teeth and the packaging was alluring. And it definitely did whiten my teeth so much so that I recommended it to everyone I knew that needed a whitener in their life. Crest is one of the best toothpaste I know and their whitening strips are also one of the best.
