Amazing!

I have tried many whitening products. But never saw much of a change. After using the Crest strips I saw a difference with the first use! A huge difference. And they don't burn like other whitening products.

Ok sa dure vraiment pas longtemps tu te met sa sur les dents. En te preparent le matin pis up cest finni tes prete a partir le resultat est la jai adorer ce produit pcest cher mais bon. Pour avoir un beua sourire sa en vaut la peine

Overall this product did show improvements. The taste obviously was not the greatest tasting. I liked that the product was easy to apply as each step also provided instructions on the back of the straps and that this product only took about 5 minutes to use.

It's true, in two hours, you will have a beautiful white smile. The problem is that after like about one year after, all your teeth are sensitive to staining ... Coffee, red wine, etc., you need to be careful.

Crest whitestrips truly live up to my expectations. My teeth were noticeably whiter after one use.

My best friend is a dentist and he says that these strips are just as effective as teeth whitening in the office. I have been using these for years and my teeth are pretty white. As long as you don't overuse them, they are great

These really work and even with sensitive gums if used properly by leaving on for the suggested time they work great

AMAZING!! I've been a white strip addict since they came out years ago. I cannot, and do not, use them on my bottom teeth because they become unbearably sensitive, but doesn't matter because no one sees the bottom teeth. These 2-hour strips are the best things that have happened to my teeth. They whiten so fast, they seal to the teeth so well that they don't slide around while you're wearing them and aren't goopy like the original crest white strips. And they really do noticeably whiten in the 2 hours. I cannot tell you how many compliments I get on my teeth, even from my dentist and hygienist! Everyone should buy these! And if you're excuse is that your teeth are too sensitive for them, just cut off the piece that wraps around the bottom of the teeth and problem solved!

These things really work!!!! brightens and whitens great!!! LOVE THEM use them often

Love them...they work awesome...will purchase in the future.
