Expensive and uncomfortable...have to put those strips and endure an hour of disgusting foam in my mouth everyday. The strips are made small now so they have trouble sticking to my teeth...i can see them slightly whiter but not worth the trouble or money

This product is really good and keeps my teeth looking great! I don't use this product often only because it's not great on your teeth using Frequently I'd say 2 twice a month. I've purchased this product many times and will continue to, the taste is a little wacky but hey it gets the job done!

I have tried other teeth whiting products and none can be compare to Crest 3d white. This product is awesome and I have refered it to all of my family members and friends. On the first day I used the strips,toothpaste and mouth wash people noticed how white my teeth were,I had great results on the first day of using Crest 3d white. People were telling me how bright and white my teeth were. I now have a new smile thanks crest 3D white.

Absolutely does what it says it does. Whitened my teeth dramatically after getting my braces off. It did make my teeth sensitive for a while even after finishing using them, but that is most likely user error. I kept them on for double the time I was supposed to usually. They stick on great and dont slide around so you can actually talk without getting a foamy, slimy spit mouth. Definitely a little pricey but totally worth it every once in a while in my opinion!!

I stand by these strips for my teeth! I whitened them about 10 years ago and just barely had to touch them up again and go in. I constantly got compliments on how white my teeth are. Personally I didn't suffer from sensitivity. Also it lasted so long because I didn't drink soda, coffee or wine! So just be smart on what your eating to prolong the results, like with any other teeth whitening products!

These strips are my holy grail!! I have naturally tainted teeth which my dentist says is healthy but for cosmetic purposes recommended only this brand. Worked after just the first time and I've been using them ever since! Results last almost a month or so!

I have lightly pale yellow stained teeth from drinking soda as kid as well as braces. I have tried whitestrips in the past and got frustrated that they didn't stay on your teeth. I am 1 week into the treatment and while I cant say I have had amazing results I feel like I can see a small difference. They have greatly improved the strips so they stick well on your teeth. I am hoping once I am done with the whole package I will have bright white teeth. Fingers crossed!

A product that does what it says—it really does work and I had great results every time I'd use it, but I couldn't stand the sensitivity it's cause in my teeth. I've never been one to experience sensitivity issues with my teeth, but these strips will do it!

Super easy to use and worthwhile. I could probably have better results if I used this regularly. Instead I use them as a monthly touch up instead of the daily use they recommend. At my last dentist visit, they all oohed and ahhed over how white my teeth are! No problems with sensitivity.

I always get compliments everytime about how white my teeth are. People also always ask me how I got them so white and I always tell them that I use Crest Whitestrips. You have no idea how many customers I have brought to Crest Whitestrips. I feel like I should be brand ambassador. I've been using these since 2011, after I got my braces off. I have tried many others, but I don't get the same results. The whitestrips whiten within 3 uses and all of the different versions work. The only problem I have with these are how they cause teeth sensitivity.
