[This review was collected as part of a promotion.] These stuck to my teeth very well. I didn't feel any slippage within the hour and didn't have a weird taste due to the gel escaping. The packets were easy to open. Directions were clear. I did notice a difference, but it was not a huge difference. Maybe using for another round would deliver stronger results. That said, I will be trying again!

[This review was collected as part of a promotion.] As a coffee drinker and smoker, i don't have the best-looking teeth I'm ashamed to say 😔 but these Crest 3D whitening strips have made a difference! This was only over 10 days! I love the difference it has made, i smile more with my teeth and feel more confident!

[This review was collected as part of a promotion.] I tried the Crest 3D Whitestrips for a week and while they did noticeably whiten my teeth, I did experience some tooth sensitivity along the way. The strips were easy to use, but I noticed a few spots where the whitening solution seemed more concentrated, which led to uneven results in certain areas. Some parts of my teeth are whiter than others, so it's not a perfectly even transformation. They work, but I'd recommend being careful with placement and maybe using them every other day if you have sensitive teeth.

These Pro Level Whitestrips are super easy to use. I asked my dental hygenist which products work and she suggested these after my cleaning. Boy was I happy with the results! I used them for a little over a week until I was happy with the brightness and now I get compliments all the time! I just repeat after every cleaning for 2-3 days to maintain. Highly recommend!

[This review was collected as part of a promotion.] Crest sent me Crest 3D whitening strips to review. I used them 7 times over the course of 10 days. I was reluctant to believe I would see any results within seven days, especially since my teeth weren't particularly yellow or gray. However, I was pleasantly surprised. I definitely noticed the difference. You can see in my before picture at the top, my teeth looked fine, but over seven treatments later there was a big difference. There was no taste, no smell, and most importantly no tooth sensitivity. I've tried whitening treatments over the years and there are times when my teeth hurt so much that I quit. There was absolutely zero issues with these. I'm very happy and will be using these again. @influenster #complimentary @crest #3DWhite

I have used Crest Whitestrips for years and love them. I tend to use for a few days in a row, once a month and really appreciate the result. People ask me how I keep my teeth so white and I always tell them to look no further than Crest Whitestrips. I use them before getting in my morning shower until I finish make up and hair, so about 35 minutes - Easy peasy!! Great product, great results at a great price! Thanks Crest!

[This review was collected as part of a promotion.] These strips do the job. I always use these whenever I have important occasions coming up. I do see my teeth brighten up after few uses. The packaging also very convenient for travel. Absolute best!

[This review was collected as part of a promotion.] The crest 3-D white strips are easy to use and effective! They application and removal was simple. The shade difference from begging to end was incredible! I have used whitening trays in the past, and my teeth were overly sensitive afterward and these white strips did not cause any sensitivity at all.

[This review was collected as part of a promotion.] The Crest 3D Whitening Strips are incredibly easy to use and are designed to adhere securely to your teeth. To apply, you simply peel off the clear liner, place the strip on your upper and lower front teeth, and press it gently to ensure it stays in place. After 60 minutes, you just peel the strip off, and removing it is a breeze. I then brush my teeth to remove any remaining ingredients. From the moment I place the strips on my teeth, I notice a cooling sensation, which leaves a feeling of freshness in my mouth. The strips feel comfortable and stay securely in place for the full 60 minutes, with no discomfort. There is no aftertaste, and the taste is neutral, which makes it very comfortable to wear during the whitening process. I was genuinely amazed by the results after my first use. My teeth appeared visibly whiter compared to before, and I could see the effectiveness of the whitening process after each use. The more I used it, the more noticeable the difference became. The packaging includes information about the ingredients, which contain the same safe whitening agents used by professional dentists. This product is an excellent choice for at-home teeth whitening if you're looking for noticeable results. I've experienced no tooth sensitivity or gum discomfort while using these strips, which is a huge plus. The ingredients include water, hydrogen peroxide, sodium hydroxide, and acrylic copolymer. If you're concerned about sensitivity, it's always a good idea to check the ingredients list, but I've had no issues with them so far. Overall, I highly recommend Crest 3D Whitening Strips for anyone looking for an effective and convenient at-home whitening solution. The results are impressive, and the experience is comfortable and easy to follow.
