These really do work! You have to use them consistently for a couple weeks. But they whiten pretty dramatically. I tried a knock off brand because I read a review that they were good but they did not stick like Crest!!

I’m so so disappointed, I’m in absolute agony after using these strips. I followed all the right steps, I also you sensodyne toothpaste, but wow I’ve never felt pain like it. This has really put me off trying to whiten my teeth ever again.

These strips work really well and are affordable! I’m a repeat user because of the convenience and price, but you definitely have to smoothen out the strip with your finger when you apply. I’ll continue to buy this product!

Shocking results saw results in thirty minutes of them being much whiter than before.These stripe are amazing for people who tend to have yellow teeth definitely recommend but I also recommend to brush your teeth every day!

Crest whitening strips are gold!! I use once a year and my teeth stay very white. I drink tons of coffee so it’s a great products. I have been getting compliments on my smile for years and I owe it to these!

I. LOVE. THESE. They keep my teeth white for a whole year. They don’t have that horrible teeth-whitener taste, and they give my very little sensitivity. I won’t get any other whiteners!

The professional strips are incredible! I have very sensitive teeth and for my fellow sensitives: cut the strips in half so you do not have to wrap it under the tooth. I never get sensitivity when I do this.

Works wonderful, however this gave me a stabbing pain in my teeth and high levels of sensitivity in the days following use. I had to stop using them, that’s how bad it hurt.

These work very well. I don’t use often, because they do cause some sensitivity, but after using, my teeth look amazing. I have tried other brands but these seem to have the best effect. Will definitely repurchase.

I’ve used this product for a long time, I really like it but it doesn’t keep my teeth white after a couple of days. Compared to other products, these have been the best over the counter white strips.
