I love the crest strips because they are so easy. They do not run or drip like messy gels, pastes, and liquids. They're painless, and do not have a fould scent or odor either. This makes them my go-to choice for over-the-counter whitening tool kits. Crest is a brand we all know and trust, and these little strips really work. I don't know about "14" years of stains, but I definitely have noticed a difference in my smile since I began using them.

These do get your teeth white but if you have sensitive teeth I would be careful. If you leave these on too long they make your teeth feel not so good. If you use it too many days in a row it makes your teeth feel weak. It does the job of whitening but I only use these once every like 5/6 months cuz they are uncomfortable

It really does the job! Whenever I have a special event or I'm wanting to impress someone, this is my go to. It's not that expensive when you look at the per strip cost and it definitely makes a big difference in how professional you look. I'm going to purchase this again and again and again!

I have used crest over the years and it has always did what it set out to do and always a number one in my book and I had all of my children use it as they have grown up and their teeth is as beautiful as ever although they are now out on their own but not my son his teeth are beautiful as ever and I still use crest even though I have tried others but I continue to use crest because it does what it say it does protect and keeps your teeth at it's best and it is no other tooth paste I prefer other then crest.

I mean, they are the go to! I've tried a bunch of other strips/whitening systems and I always go back to good old white strips. I do have to space them out (can't do every night) due to next day sensitivity. But I think that's just a person to person thing. Some people will get it, some won't.

This has been the most effective teeth whitening product I have ever used. I immediately used it after I got off my braces and my teeth look amazing. I have received so many compliments about how white my teeth are! On occasion, my teeth do get a little sensitive after using this product, but that is to be expected from any whitening product.

I'm wearing these white strips as I write this review LOL. I think these white strips do a great job. They do make my teeth visibly whiter. Just make sure to not go over the time on the box you're supposed to wear them or your teeth will be more sensitive the next day.

LOVE these whitening strips. I didn't think an at-home system would work - these make a huge difference. Have used several times before and will use again. Sometimes teeth/gums do feel oversensitive and need to break for a day or two before resuming.

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!

I recently started using these and it's been about 3 days so far. I put them on two nights in a row and my teeth were pretty sensitive to it the next day so I started doing it every other day. I've heard really good things so I can't wait to see how my teeth turn out
