I spent alot of money on Zoom only to be very disappointed with the results. After years of living with discolored teeth I decided to have Caps put on my 2 front teeth so I had to whiten the others, I tried whitening trays with little to no whitening. I tried these strips, which stay in place very well. The results after a few uses was astonding! Im so happy I found this! Now with my new front 2 teeth my smile is wonderful! Just wish I would have done it before 41 years of age! :)

These are nice but if your teeth are sensitive you might want to give them a break every so often they do work they are just sometimes a bit of a hassle because of the fact that they do make you feel a little bit uncomfortable if you are sensitive to whitening if you're not wanting to pay the professional price this would be a great option

These strips make your smile not only healthy looking but YOUNG looking too...nothing says age like off color teeth....no matter how much you spend on your wrinkle creams....NOTHING makes a more obvious, quicker difference than whiter teeth! And these strips are easy, effective and stay PUT! I love these strips and it is part of my beauty routine...a MUST.

I really did like this product. Drink coffee and I do smoke so as a dental assistant I felt like my teeth could be whiter and I purchased and I did see a difference with in a week I did get sensitive to it so I had to get toothpaste for that but it does work and I do record as long as YOU DONT HAVE resin fills or crowns in front teeth as those will NOT change colors and it will stand out as your teeth get whiter.

These are definitely my favorite whitening strips. I only use them before special occasions and events but they do make a difference. I use them every other a day the week before I have some sort of event and they work. They can make your teeth sensitive so I don't recommend using them regularly, but it's a good product.

I honestly loved these at first J began seeing a difference although I hated the texture and taste of it. But I have a cap on my tooth because I chipped my tooth a couple years back so underneath the cap is exposed nerve making it very sensitive. The paste basically stripped the layers of my cap away till I could feel the exposed nerve 24/7. It was hell and I then had to get the cap removed and get a new one. Maybe the package says this somewhere or I was being really dumb but just be careful and know what ur dental history is like. I hope this helped!!

I've been using crest 3d whitening strips for over 3 years and I find myself always getting compliments on how white my teeth are. On a regular I would say I drink at least 4 cups of coffee A DAY, sometimes more -_- so this product definitely keeps my teeth from yellowing. Highly recommend crest 3d whitening strips!!

I have been whitening my teeth for years, I go thru spurts where I will whiten for 3 months at a time. Usually I find that my teeth get a little sensitive... I've been using these crest white strips for the last month, daily use leaving them on for 30 mins and I have NO sensitivity. my teeth are dramatically whiter, and they are easy. Would highly recommend!

The best at home whitening strips I have used thus far. I tried using a different brand but it does not give me the results I am looking for. I have sensitive teeth and its ok for me. One negative thing about these is that I wish they still made the 2 hour express strips.

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 :)
