I like the fact the strips stay in place and you can go about your normal business. I've even taken them to a girls day to share. I do wish they were wider to fully cover the back of the teeth as well. This is my preferred brand and have purchased them several times.

Hace dos meses empezamos a usar estas tiras,mi esposo tenia los dientes muy amarillos y en 3 semanas sus dientes se aclararon mucho,él está muy feliz pues un blanqueamiento en el dentista es super caro,en cambio en mis dientes no he notado mucho cambio,quiza porque los mios no han estado amarillos,pero tampoco son super blancos,al menos sé que funcionan y no nos produjo ninguna sensibilidad ni dolor y lo malo es que no siempre pegan bien,algunas tiras parecen no tener mucha fuerza para pegarse a tus dientes y se resbalan

[This review was collected as part of a promotion.] These whitening strips were really no good for me. I have sensitive teeth and avoided strips for that reason but when I saw these were specifically made for sensitivity I was excited. Well my teeth hurt. I tried the strips numerous times and every time they left my teeth in pain for hours. Past that the strips were horrible to try to keep on properly. I did noticed a smidge of whitening from the times I used them so on that front I’d imagine they work okay. But due to the pain from them I won’t be purchasing or using the rest.

I used this product after noticing my teeth were stained from smoking and drinking dark sodas. It really works great after only about using three strips I noticed a huge difference of about three shades. After i was done with the entire treatment I would say i've went 5-7 shades whiter! I use these every month once a month to keep up the whiteness and its great everyone notices how white my teeth are now :)..... I would recommend these to everyone!! XOXO

I used this product for some time now, I think it is one of the better brands of whitening strips. However I have not tried the other whitening strips Crest offers. In the near future I plan on purchasing the other white strips because this one did show great results with me... I also know whitening will make your teeth sensitive, this product kept it to a minimum. .. I recommend :)

These are the best whitestrips. After using them for only 7 days (in a row) my teeth are perfect and now I just use them for maintenance. I started noticing a change by the 4th day. Well worth it especially when they have 50% off! These strips are as good if not better than professional zoom whitening!

After purchasing the crest 3D white strips I was very nervous to try them because I have very sensitive teeth and was afraid of them hurting after. I tried them for two weeks and surprisingly never had an issue! I am a college student and work in retail so I'm always trying to improve my appearance. These are a great, affordable solution to do so. I now receive so many complements about how white my teeth are and people even ask if I get them done professionally. I tell them about the 3D white strips and my great experience and they are shocked! Many of my friends have purchased after hearing what I had to say and they also had great results! These are deffinatly the best whitening product a person can purchase.

[This review was collected as part of a promotion.] I’ve been using the Crest 3D Whitestrips Professional Effects for a few days now, and I’m honestly impressed with the results. The strips are super easy to apply, and I love that they don’t slide around while I’m wearing them. After just a few uses, I noticed my teeth looking noticeably whiter. There’s a slight sensitivity, but it’s nothing major. Overall, I’m happy with how much brighter my smile looks, especially for a drugstore product. If you’re looking for an at-home whitening option, this one’s definitely worth considering!

I loved using the Crest 3D White Whitestrips Professional Effects. They have really improved the look of my smile and everyone comments on how white my teeth are now! My patients that have tried these have also been very satisfied. I would recommend them to anyone who is looking for a bright white smile!

[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!
