Don't order online!

Liked results before when used. I ordered these on line last night of sale because I wasn't going in store until the sale ended. Came in a plain cardboard box inside another cardboard box, no manufacturer packaging, no instructions. I don't even have any idea of the expiration date because it would be on the packaging that was removed. It is known they are not as effective past expiration. And to top it off, it looks like some type of hair or fuzz all over in the darn box! I may try to exchange these in store for a proper package!! I would recommend but don't order on line if you want to know the expiration date!

Noticeably Whiter Smile in Just a Few Days

[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.

Súper teeth whitening

[This review was collected as part of a promotion.] I'm the number 1 fan of these Crest whitening strips. They are effective and a good price. I love that I can do it from the comfort of my home, and people ask what I use because my teeth are white. This kit is super effective, the best package for your whitening teeth, like the professional whitening Yes, I highly recommend it. Thank you

Product no longer as effective.

Definitely not as effective as the product used to be. I have used Crest whitening strips for almost 15 years and always saw great results even after just 3 or 4 days of treatment. (I usually whiten my teeth only once per year). I just bought this pack of Professional Effects and have gone through the full treatment and my teeth still look slightly yellow. Clearly Crest has reduced the quality...like every other company out there today who rips people off with 'shrinkflation.' Really disappointed.

Quick and easy way to whiten your teeth!

[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.

So great!

[This review was collected as part of a promotion.] Thank you so much to Influenster and Crest for sending me this product to try in exchange for my honest review! I have used this product before and I love it so much! It truly is the only thing that really works for me. It does burn and can cause sensitivity if you use them too often or keep them on too long, so just be careful because of that. However I think this is a great value because you get so many strips in the pack for a price that it much better than professional whitening and can be used in the comfort of your own home. I do produce a lot of saliva after using, but I like to put them on before the shower so I can easily spit out the excess. They are not too comfortable but you get used to it. My only real problem with these is that keeping them on for a full hour is a long time. However, I believe that they do sell ones that you keep on for a shorter amount of time. Thank you again to Influenster for sending me this product to try!

Crest white strips

Strips came in a plain cardboard box not in original packaging. Very odd!
