Awesome Results!!

I had been wanting to try the strips but was afraid it wouldn't take 60 years of stains off my teeth but they did!! I noticed a difference after the first use but there was a really big difference after using for the first week. Now I can smile and not feel so self conscious. Great Product!! Highly recommend!!

Great price!

My dentist recommended I try Crest white strips. They fairly expensive so I checked Sam's and they were $49.95 for 20 sets you use for 20 days and 11 sets you use once a month. They work. My teeth are starting to look whiter after 5 days. I recommend them. Great value.

Good price on a quality product

Good price, not enough time to fully evaluate for an accurate review. My Dentist highly recommended this product and advised that Sam's Club offered it for a low price.

Sparkling Smile

These work just as good as what you would receive at the dental office.

Crest White Strips

We’ve been using these for years and have never had to pay for teeth whitening professionally! They work just as well or better!

Love this kit.

Definitely whiter teeth. This kit has 20 days everyday and then 11 maintenance strips once monthly for a hour. I’m on day 13 already and my teeth are so much whiter even the lower part of my bottom teeth. This kit was a great idea and works well. Definitely recommend this kit.

Disappointed

This product has been modified and is not as effective at whitening as it once was.

Expensive and difficult to use

1. Crest 3-D white stripes are expensive per each use. 2. They were difficult to use, and I repeatedly had problems trying to keep the bottom strip on my teeth. Three times the strip would not stay on my lower teeth, and I had to throw it out making each treatment even more expensive. 3. Each time I use the crest 3-D strips, my teeth became uncomfortably sensitive and remained so for about two days. 4. In fairness, I do have acid erosion on my teeth that could have contributed to the sensitivity. However, I have used other whitening products that did not cause the sensitivity that I experienced with crest 3-D strips. 5. I won’t buy these strips again and am considering returning them to the store.

We strive to offer our consumers a convenient and effective solution for whitening their teeth at home, and we are disappointed to hear that you had some sensitivity and issues with getting the bottom strips to stay on your teeth, Roxane. All of our products go through extensive testing to ensure their effectiveness and safety, and this is not at all the experience that we would like you to have. We can understand the frustration with those strips not sticking, and we would like to offer some tips to help with keeping those in place. Our Crest Whitestrips stick better to dry surfaces. You can try drying your bottom teeth first with a paper towel, tissue, or by breathing in, then apply the strip to dry teeth. It is also important to note that some users may be more prone to sensitivity than others, and, as with any teeth whitening product containing peroxide, sensitivity or soreness may temporarily develop. To help with avoiding sensitivity, we recommend using the strips every 2-3 days, or alternating using them on the top and bottom teeth. If the discomfort persists, we would suggest discontinuing the use of the product. We would love a chance to learn more about your experience so we are better able to assist you as well as gather some additional information for our Quality and Safety Teams, and we invite you to give our team a call at (800) 395-8423.
