I think this is the kit I use. I typically use these right before a big event so not necessarily they’re “intended continuous use” that is how you’re going to get really noticeable results. But it definitely takes the edge off and I have gotten compliments on the whiteness of my teeth.

I use this product to take away all of the stains from drinking so much tea lol. While they do work, they do take a little while and it does dry your mouth a little. Regardless, I still recommend this product to those that are looking for results that show.

Great teeth whitening strips that actually work. I see a difference after at least a week of use, and feel like I'm removing any/all stains from my teeth. I have pretty sensitive teeth so I typically need to take a break after a couple of days, as these strips lead to a 'tingling sensation' almost like a brainfreeze in my teeth. But totally manageable and less severe when taking breaks in between wear. Highly recommend for accessible, at-home teeth whitening! 

Why is it that every other one I use has so much adhesive on it, that it is bonded to the clear plastic tray. In an attempt to remove it causes the product to distort and lacerate to the point it is too deformed to use. Considering the price of the product, one would expect better QC of the application method.

I’ve used Crest whitening strips for years and in my opinion, nothing works better. They leave you will professional looking bleached teeth with a lot less cost to you. It gives a nice even application and it doesn’t take away your Enamel leaving you sensitive. I highly recommend!

I love them, 3D WHITE WHITESTRIPS PROFESSIONAL EFFECTS they do work! The only thing that I found wrong was that on occassion I would pull the whole plastic piece off instead of just the strip and then it was a pain to get the strip off. But it was worth the hassle. WOW these things work. The BEST!

[This review was collected as part of a promotion.] When it comes to oral health and teeth, yes, the brand is very, very important. Crest is definitely a brand I trust and have been using for years. Crest teeth whitening strips provide fast and visible results at a reasonable price, at home. It did not cause any sensitivity or negative side effects on my teeth and gums. It is the definitive solution for maintaining current whiteness or removing old stains.

[This review was collected as part of a promotion.] I’ve been using the Crest 3D Whitestrips Professional Effects for a few days now, and I’m honestly impressed with the results. The strips are super easy to apply, and I love that they don’t slide around while I’m wearing them. After just a few uses, I noticed my teeth looking noticeably whiter. There’s a slight sensitivity, but it’s nothing major. Overall, I’m happy with how much brighter my smile looks, especially for a drugstore product. If you’re looking for an at-home whitening option, this one’s definitely worth considering!

I've been using these for a few years now. These are my absolute favorite! They make my teeth a little sensitive after using but other than that, they're great! I notice a difference when I do use them. I recommend this to anyone who needs to start using whitening strips!
