This is one of the best whitening systems that I've tried. Very easy to use, and amazing results. I often get people asking me what I do to whiten my teeth, always surprised when I say just use Crest Whitestrips. I highly recommend this product for anyone wanting a whiter smile.

I wasn't sure how good this product worked, but after using the strips I could see a difference in my teeth immediately. Years of coffee drinking had stained my teeth, and I didn't want to pay a dentist the exorbitant cost to hopefully whiten my teeth. I have only used the strips two times now but I will be purchasing them again after seeing the results.

They whiten great but they make my teeth very sensitive, so I have to use them sparingly because of the sensitivity.

This product did make my teeth whiter but it is very pricey and it made my teeth so sensitive after. My dentist told me never to use it again!

This stuff is soooo expensive Why bother? So many other things you can use for whiter teeth. Also, don't count out household products that work probably better.

I wanted to love this product, but unfortunately it gave me excruciating tooth sensitivity that lasted for hours! I'm sure this would work great for people with normal teeth.. but for those with any sort of tooth sensitivity whatsoever, STAY AWAY!

They are easy and they work really good! They whiten your teeth instantly and you won't be able to stop smiling after.

J'adore ce produit et l'utilise depuis des années à raison de 2 fois par année et il laisse mes dents blanches et éclatantes toute l'année . Les bandelettes sont simples à appliquer et vous pouvez même parler avec sans que la salive coule de partout . Toutefois j'avoue que ce n'est pas super agréable en bouche mais ça en vaut la peine .. Le prix toujours trop dispendieux et rarement en spécial mais moins coûteux qu'un traitement chez le dentiste . À essayer absolument .

This whitening kit sticks well to teeth. It does a great job of removing stains and whitening effectively even after one use. I don't use a lot or consistently because it makes my teeth quite sensitive and I don't want to peel my enamel. This is good for a quick fix, it brightens my teeth after one use.

I wasn't impressed with this product. I found it was difficult to get off my teeth because it was so sticky. It was actually quite painful trying to get the strip off. After all that pain it didn't really whiten my teeth. I will just stick with the toothpaste.
