I bought these because so many people swear by them but unfortunately I didn’t get the results I was hoping for. They made my teeth incredibly sensitive so I couldn’t use them every day which may be the reason I didn’t get good results, but they were disappointing on the whitening aspect. I will be looking to try a different product next time.

Finally, a product that meets and exceeds it's advertising claims! I am 52, smoke and drink lots of coffee and as a result, my teeth had yellowed badly. I have used Crest whitestrips in the past with fairly good results, but the twice daily application was messy and time consuming. Professional whitening treatments were not in my budget, so I gave these a try. After just one treatment my teeth were whiter than after a month's use of the old strips. Crest 3D also removed a dark spot on my front tooth I'd had since childhood that had remained despite routine dental cleanings. I was so pleased with the results that I bought a box for my daughter. Thank you for a wonderful product!

These whitening strips greatly helped my smile. Before I used them my teeth were so yellow that it was embarrassing to smile. Using these along with crest whitening toothpaste made my teeth look better and made me feel more confident in my appearance.

I absolutely LOVE these! I used them to whiten my teeth 10 days before prom and I saw a difference. You must brush your teeth before using them of course. They do work fast. Even my dentist noticed how white my teeth were. If your teeth are sensitive it will hurt more. It doesn’t protect your enamel. But your teeth are visibly whiter in half the time.

My teeth are very sensitive when it comes to whitening strips so when it comes to them I tend to be super careful. I only use these once a week and I can see an amazing change in my teeth! They aren’t to harsh but I would definitely recommend for anyone wanting whiter teeth!!! Plus, it does not take up a lot of time throughout your nightly routine.

This is my yearly or bi-yearly go-to whitening product! They just work! I stopped using them for years because they do make my teeth a bit sensitive, but after trying several other products (that didn’t work at all) I came back to these! Even though I only use these about every other night (sometimes every third night) due to sensitivity issues, the end result is still always amazing! Interesting tip I learned from my dentist years ago: just because they recommend you take them off after 30 minutes, does not mean they stop working after 30 minutes! To get more bang for your buck, you can leave them on a bit longer to get more whitening. Due to my previously mentioned sensitivity, I just add on an extra 5-10 minutes each usage.

These white strips are great! They stay put, don't have a weird taste, and since they stay in place, you don't get gooey whitening product seeping into your mouth and gums. I noticed a huge difference after only one strips, and my teeth haven't been this white in years after using 5 strips total. Can't recommend this product highly enough.

I use these with the crest whitening tooth paste and the combination just works really well. This pack comes with 12 pairs of strips (top and bottom) and they work so well I started by doing 12 treatments straight but now I just use one every once in a while.

After just one use my teeth were whiter. I use it twice a month or so. Maybe more if I have an event coming up. I have sensitive teeth but I don’t have any sensitivity using these! Price seems high until you price a professional whitening treatment at the dentist. Trust me. The previous version of these slipped around as soon as you put them on. They will not stay put if you were trying to talk... The never version is “slip proof”. They have a better grip to the teeth to start. I still don’t like to talk too much with it on.

I get asked all the time if I've had my teeth professionally bleached, and I owe these strips for that! I followed the instructions on the first box and now I'll use them every not and then for maintenance. They can make your teeth sensitive when using them a couple days in a row, so I try to prepare for that using toothpaste designed to help combat sensitivity just while I'm using these.
