Makes my teeth so much lighter

I love crest 3D white strips they do work! They make my teeth so much whiter the only downfall is that it makes my teeth sensitive. I can never finish the box if I use it daily as my teeth will get sensitive to even air. But it does make my teeth look beautiful. It’s best to use the strips occasionally to avoid that. I would recommend this product

Good, but...

These are pricey. Definitely purchase when on sale. If you have sensitive teeth, watch out! They kill. Use a sensitive toothpaste prior to and during whitening. These do work, but I feel like they only get your teeth so white, then stop.

Worth a try

I like these strips, they seem to work better than others I have tried in the past.Didnt work quite as quickly as marketed but definitely showed some improvement.

Works okay

These work ok. They do lighten my teeth but they hurt my gums and also my lips. Whitening is temporary. You need to keep purchasing them. Don't like the fact that I need to constantly repurchase them and I worry about the long term effects.

Works, but not worth the pain!

I have gotten many free samples of this product over the year, so I decided to give it a shot. What a mistake!! I don't normally have sensitive teeth, but after using the strips (according to the instructions), I couldn't sleep because my mouth was in agony. I waited before attempting to use them again, this time slathering my teeth with sensodine before AND after, but I will still in a ton of pain the next day. My teeth were whiter, yes, but for me its not worth the day after.

I received this product for free in exchange for my personal review. Crest 3D White Luxe Supreme Flexfit Whitestrips definitely lives up to its name. It was super easy to use. It takes minimal effort to put them on - just a few seconds per strip and then you can get on with your business. The only downside to the strips was that after the first time, it definitely made my teeth very sensitive. I had to start using toothpaste for sensitive teeth because it was uncomfortable. But other than the sensitive teeth, everything else is great and you're left with whiter teeth for sure!

I find that strips work well for a short time.

Amazing product! You can tell just after a few uses that your teeth are whiter. I'm not a fan of the 'gucky' feeling in your mouth. It is an expensive product.

My teeth were noticeably whiter after my first use. I found them easy to use and fairly convenient. I found it left my teeth a little sensitive after use. I would recommend this product.

The whitening strips whiten your teeth as promised! My teeth looked noticeably whiter after trying just one whitestrip. I find them a little on the pricey side, but they do perform! I did notice some minor tooth sensitivity after using them, but that only lasted for 1 day. I would recommend trying these, they work!
