When I tried Crest Whitening it did wonders for my teeth. And I didn't believe that it would because I've used other products that said that they would do the same thing and they didn't. So I was quite skeptical. But, this one is one of the best I've ever used in my life. It was very sensitive to my teeth and the packaging was alluring. And it definitely did whiten my teeth so much so that I recommended it to everyone I knew that needed a whitener in their life. Crest is one of the best toothpaste I know and their whitening strips are also one of the best.

I loved the whitestrips. I noticed a difference after the first use. I received a whitening system (trays and bleaching solution) from my dentist and was told to wear them overnight. Not comfortable at all. I can put the Crest 3D whitening strip on before I take a shower, leave them on until I am finished and see a difference. I have already recommended the to all of my friends and will continue to do so. Thanks Crest for making a great product that is also so easy to use.

Half of the upper strips do not adhere. I applied each day, the same way. The lower strip adhered each time; the upper strip would not adhere more often than not. I'm on day 9 and notice no whitening whatsoever. Will probably toss the remaining strips. I'm very disappointed. My high opinion of Crest products has vanished. No, I do not recommend this product.

These definitely work to whiten your teeth in an easy at home way. They are definitely expensive but I think that is par for the course with all whitening strips. You cannot wear these for too terribly long though if you have sensitive teeth. After about 15 minutes my teeth begin to feel like they have lightning shooting through them. Once I remove the strips the pain subsides.

These white strips work well and are really good at not falling off or sliding around while using. These products can be expensive depending on the type and how many you prefer. One thing that I would recommend is not using more the 3 days for sensitive teeth.

This is a really great product that I found to be worth what it costs. It whitened my teeth many shades even though I did not use it daily (I used it more like every few days for a month or so, then kind of “as needed”) and it really grips onto teeth - you can even drink water with them on. As always, you do need to read directions carefully. They occasionally cause some sensitivity for up to a day after but it's not a problem as long as it's expected. Note that the Crest website often has amazing two-for-one deals on these kits!!! Even more worth it!

I used Crest White Strips when they first came out, and they worked wonders. But, these 3D Advanced Seal strips are the new and improved version! These strips stay in place, and now I can talk while wearing the strips! (Before it was a challenge to talk while wearing the strips). With these new 3D White Srips there is no uncomfortable flavor even after I remove the strips. Best of all, I noticed a color difference with my teeth after just two uses! Totally recomend these to anyone who needs to brighten up a smile!! :D

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.

No slip whitening strips from the 3D white kits are my favorite. I have had good luck with the less expensive versions of these but the no slip is what really keeps me buying these when I need them. With no slip it's nearly fool proof way to whiten your teeth to dental office/treatment quality for nearly 1/5 of average costs!

All I can say is I am totally blown away by the results I have gotten so far. I am a die hard starbucks fan and it was starting to show by my smile. I would notice in pictures my smile looked dull and not very white at all. About 6 years ago I went and had my teeth whitened at the dentist and it could not even begin to touch what the crest white strips have done!! I am thrilled with the results after only 3 days and it's only going to get better! :) If you have ever wanted a whiter, brighter smile, you will NOT be disappointed with the professional 3D strips!!
