[This review was collected as part of a promotion.] I’ve been using Crest for years and absolutely love it! Using Crest 3D Whitestrips Professional Effects has become a part of my weekly routine and has made a huge difference in my smile and overall confidence. I recommend them to all of my friends!

I used these whitening strips before my wedding, and they really helped me achieve a beautiful white smile! I drink a lot of coffee and red wine, so I also try to use these every 6 months to help maintain my smile. The only reason I gave the product a 4 star, is because I experience some teeth/gum sensitivity (only last one or two days) which the label does warn could happen and also the price is slightly high. But I think it’s worth it!

These REALLY work! Even after one use I could see a difference, but the real trick is to use them daily if you can and results are insane after a few days. I’ve had several people stop me mid conversation and say “wow your teeth are so white!” There are 2 downsides in my opinion- the “zings” you get after a good amount of time using these (sharp shooting pains that go away as quickly as they come) and the taste. But if you can get past those two minor details the results are so worth it.

Crest 3D White Luxe Teeth Whitening kit is so worth it! It whitens my teeth and it costs so little compared to what it costs to have done in the dentist’s office. These strips get rid of coffee stains and brightens my smile! Well worth it and I love the ease of this at-home treatment!

They work! I don’t have before or after photos, but I can say this, I smoked for ten years, have been drinking coffee for fifteen and wine for five. My teeth were definitely it white to begin with, but after four applications of these, they are much closer to white than not. I think by the time I finish the box, my teeth will be glowing. Also, I have sensitive teeth and these don’t really bother them or my gums, which is awesome because even some toothpastes cause painful sensations, these strips don’t.

These whitening strips were my first I've ever used, and are still going strong many months later. I have bought another set just to keep up. These aren't going to give you a bleaching white smile, but will get some nice shades of white that are noticeable and look good on a smile.

I do see a difference when I use this product. My teeth do appear whiter. However I have sensitive teeth so I use the sensitive option. I do find sometimes they don’t stick on my teeth right away. I have to wipe my teeth so they aren’t too wet and then they stick just fine

I am a dental hygienist and was Leary. I bought this for my boyfriend who had reallllly yellow teeth. The old strips were terrible, they slipped if and were annoying. These new strips are awesome. And they reallllly work . His teeth have lightened up a few shades and look great :)

I love Crest 3D Whitestrips....they really are far better than any of the whitening toothpastes out there. They are worth the time, money and effort. Even my dentist's office recommends them. They really add the extra shine, especially for tea and coffee drinkers. Thanks Crest.

I am only 5 days in and I have already noticed an extreme change in color of my teeth. You wear the strips for 1hr a day. The strips are big, so I cut them in half (horizontally) and get double the use out of them. My teeth are usually sensitive and I have not experienced much sensitivity at all throughout the 5 consecutive days I have been doing the treatment.
