I've been buying crest whitening for years now and my teeth are white. Every dentist appt I have I get a really nice compliment like "wow, you have really nice white teeth". They would ask what I'm using. I would say, "I'm just using whitening crest toothpaste". They can't believe it but its true. About 5-6 years ago, I have tried using crest whitening strips. I tried it for a while and stop after I saw the result. I couldn't afford the price and besides my teeth were already white. So, I decided to buy the crest whitening toothpaste and whitening mouthwash which was affordable. Not only I can afford it, but it also work. I work in a retail store so I'm required to smile a lot. I get so flattered and happy when my customers say " I have a nice smile and a nice white teeth. Once again, customers would ask what I'm using. I would say "CREST product":)

[This review was collected as part of a promotion.] These crest white strips are so helpful when you need a quick teeth whitening! I’ve used these for a couple days now before bed and I already notice a difference! It’s gradual but definitely there! I’m hoping for even more after a few weeks of use! They are a little tricky to apply but I’m starting to get the hang of it. I found that making sure your teeth are somewhat dry helps them stick better. Eat at home whitening!

I purchased the Professional grade strips in hopes that they would brighten my smile a few shades, but after using them for nearly 4 weeks, I've not seen a significant improvement. I had high expectations based on some of the reviews, but unfortunately, these fell flat along with my smile.

I love the old Crest Whitening Strips, but these new ones are terrible. They don't hold, I have to keep checking and making sure the strips are on my teeth. I didn't have to do that with the old ones. You guys are losing quality fast! I'd say save your money for a whitening treatment. ESPECIALLY if they're going to keep producing these low quality strips.

Although it states it will not work on porcelain crowns it actually did on mine! One of my front teeth is a porcelain crown and I got it before I became a heavy smoker and cola drinker. It yellowed along with the other teeth but somehow the strips brightened it back to its original color. I have had no gum irritation or tooth sensitivity so far. The strips are easy to use, come off easily and leave no residue. I saw results immediately and am now on my fourth day and the results continue to astound me. Great product!

My teeth have never looked so great, love flashing my pearly whites thank to Crest! Crest and oral B are the only oral products my hygienist recommends. Fantastic product, keep up the great work Crest! So happy to be able have professional results in such a short .period of time at home.

This product is absolutely the best way to whiten your teeth. I am thrilled that I can do it in the privacy of my home and see results that are fantastic. I get compliments all the time about my smile and I tell everyone about my Crest Whitestrips. So glad this is wonderful product is available.

After only 2 uses I noticed a whiter smile. Im axious to see how much it improves with each use. The upper strip stays in place perfectly, no slip, and its not messy..My only complaint is the bottom strip. It needs to be longer. I have had some trouble with the lower strip staying in place and not sliding around. Overall tho, great product and is totally worth the price!

Crest Whitestrips efficacy has become reliably unpredictable. I've used Crest whitening strips for many many years and always had stellar results, however, sometime in the last 5 or so years, the branding and varieties have become so diluted that 1) there is clear or understandable differentiation between the sets and 2) the results are so incredibly lackluster that you're left wondering how these are being marketed has "professional". I learned that years back, I had better results from boxes purchased in stores rather than online because store temperatures are typically regulated better. However, after this last set of professional effects, all whitestrips truly are a total gamble. There must be a reason their "highest quality" strips are always 50% off.

[This review was collected as part of a promotion.] I've always been skeptical about at-home teeth whitening products, but the Crest 3D Whitestrips Professional Effects kit truly exceeded my expectations. After just three days of use, I noticed a significant difference in the brightness of my teeth. The strips are easy to apply and stay in place securely, allowing me to go about my daily activities without any issues. One of my main concerns was tooth sensitivity, but I was pleasantly surprised to experience none throughout the treatment. The results are comparable to professional dental whitening sessions, but at a fraction of the cost. If you're looking for an effective and convenient way to whiten your teeth at home, I highly recommend giving this product a try.
