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

My favourite teeth whitener!

I've definitely tried every product out there designed to whiten teeth — from strips to pens, to UV and professional whitening through my dentist. THIS product gives me the best results time and time again. The only negative about this product (which is the same for ANY teeth whitening system) is it leaves your teeth feeling very sensitive. So if you don't already use a sensitive toothpaste, then you'll need to invest in some.

Works good

I’ve bought these a couple times now. Out of the crest white strips family these are definitely the best ones. You do have to use them a couple times a year to stay white BUT I would definitely buy again.

Whitening

I try it for the first time with a company and a was very septic at first. So i try. And it’s work! 30 minute and BAM. I see a big difference. But it say to not brush your teeth before that may cause sensitive. And i would not recommend that one for sensitive teeth. But the one for absolutely. Why not to try.

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.

Love

These are my favourite products for whitening! You really see a difference after the first strip. The only downside I've noticed is that my teeth are usually a bit sensitive to cold for the next day or so.

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.

J'utilisais régulièrement des bandes blanchissante auparavant, pour avoir des dents blanches. J'utilisais toujours des Crest 3D white et ça fonctionnais vraiment !
