I love this product and use it once a year to keep my smile pearly white ! You can see the difference pretty much immediately, which is a must if you're a coffee or wine drinker . The only teeny tiny downfall for me was that my teeth felt pretty sensitive for a day or two afterwards. It does go away though . It's a bit expensive but I find I only need to use it about once a year. Would definetly recommend this to a friend!

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!

I really like this whitening kit. I've used it for many years and found it to work wonders. It removes stains and leaves my teeth looking great. The only problem I have with it is sensitivity after using it. My dental hygienist suggested that I use a sensitive toothpaste before and during whitening treatments and it helped a bit.

I'm looking for a quick fix for whiter teeth without having to go to a dentist. I will be giving this product a try.

Effectivement, ce produit est efficace Et ne me fait pas mal aux dents Et les blanchit.

I love 3D Whitestrips intensive. It's easy to use it. The result is so nice.

I love my teeth and love white teeth even more! This product came to me in a sample pack and this past weekend I tried them as I had a wedding to attend on Saturday. I put them on and two hours later, (as directed), I took it off. I thought they were really effective; however, my teeth were incredibly sore the next day.
I usually use professional whitening from my dentist and I thought maybe my teeth have been 'over whitened; but my boyfriend also used this product and felt his teeth were really sensitive the next day as well. If I were to use this product again, I would take it off sooner than the 2 hours.

love it , i find your teeth look much whiter and feel more clean with the product, a bit pricey but worth it , does a good job

I received Crest 3D White Whitestrips as part of the Product Review Club! Based on my previous experience with whitening products, I didn't expect much out of Crest 3D Whitestrips. I was pleasantly surprised that these Whitestrips actually do perform as advertised!

First off, they are easy to apply and stay on for the recommended 2 hours. My results were most apparent in the first few applications. I experienced mild pain after my first application which was different than what I would call sensitivity. A pain in which it was hard to drink the extremes of hot or cold fluids - which personally, has never happened before. Based on this pain, I followed the instructions thereafter and increased the gaps between my usage to at least 2 days. Overall, the result using the Whitestrips for 7 days are my teeth are exponentially white - a shade that they've never been before! And the best part is, that it is a prolonged effect that has been lasting a couple weeks after usage as well.

This is a product I will use again in the future. If you're looking for increasingly whiter teeth and willing to pay for a pricier product, I definitely recommend Crest Whitestrips!! Happy teeth whitening to all!

The Crest 3D white strips did do what they claimed, and were easy to use. The length of time that you did have to keep it on, was a bit bothersome. The strips did stay in place very well, and I received slightly above average whitening.

I may consider buying it again if a special occasion was coming up, and the price went down, and I would recommend it to a friend if they were in need of a product to try.

Please note I was fortunate to receive this product free to test.
