I had tried the classic whitestrips in the past and seen some whitening but when I used the 3D Professional Effects I could hardly believe my eyes! Last night I used them while tanning and my teeth where glowing white when I got out! Tonight I used them without tanning and the results just keep amazing me! I'm so happy with how white my teeth are and have only done 2 treatments! If you're considering buying them and reading reviews trying to make your mind up stop reading and go buy them! You won't regret it and with the money back gaurantee you can't go wrong! Thanks Crest!

[This review was collected as part of a promotion.] I received the Crest 3D Whitestrips for free from Influenster in exchange for my honest review. After using the Crest 3D Whitestrips for one week, I definitely noticed a visible improvement in the whiteness of my teeth. The color looked noticeably brighter, especially around the edges where I had the most staining. However, I did experience bad sensitivity throughout the week—mainly sharp zaps during and after the treatment. While the results were great in terms of whitening, the sensitivity was tough to deal with. If you have sensitive teeth, I’d recommend using them every other day or following up with a sensitivity toothpaste.

The one and only. I get constant compliments on my teeth. People question if I’ve gotten them professionally whitened and my answer is always crest white strips!! I make it through one pack a year! My teeth get a little sensitive because of my gums but that’s a personal problem that doesn’t effect everyone! I would truly recommend, it’s the same effect as professionally getting them done, just cheaper! So worth it!

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.

These whitening strips definitely whiten your teeth. I have only tried this brand and it works great! I do wish the bottom strip was longer though, it only covers a few teeth. It would be great for both strips to be long enough to cover all your teeth! After a while it makes your teeth sensitive so I recommend using them once a week or when needed because it does hurt at time.

These are very very expensive. I am not a fan of the price that they do get the job done. I also did not realize at 1st that they are a treatment and each strip is to be used in sequence not once every once in a while. I was not aware that eater Box was a sequence of treatments not just one treatment every now and then

These whitening strips are a must have if you talk to a lot of people throughout the day. You put these strips on for 30 minutes, and after you take it off there is a significant difference. As someone with a smaller mouth, the strips are sometimes hard to put on.

This is the only teeth-whitening kit I will use! I have tried everythingggg, and this is the only product where I can see a noticeable change in color AND it doesn't burn too much. I usually just use it one a day for 30 minutes until I get the desired whiteness. I try not to exceed a week of use because that's typically when my teeth start to become sensitive.

I loved these, i have sensitive teeth and it did not hurt like a different brand did. I got so many compliments from people because it made a noticeable change in my smile. I am a heavy soda drinker and I didn’t have to change my habits and the strips still worked

I don't really notice a difference between this and their other strips in terms of results. They pretty much all work the same. I use these when I need an extra boost it quicker results. Overall I don't think the price jump is justified when I get the same results from their glam white strips.
