This product was highly effective when I used them years ago. I've tried off-brands and they haven't worked as well. My only complaint is that I have difficulty leaving them on my teeth for a full half hour. They make me salivate a great deal, and they slip off my teeth as a result, usually the bottom. I often mitigated this issue by doing the top and bottom teeth separately, but of course this takes longer.

I was pleasantly surprised by their kit. Very easy to use. Didn't make my mouth feel “weird” and my teeth feel and look better after only a few uses. I'm a heavy smoker and coffee/soda drinker. Always look out for coupons in combination with sales at the drugstore or grocery. Best time to buy.

I went for my cleaning this week and my dentist actually thought I had went to someone else to have whitening done. We had discussed it so many times but after reading horror stories on the internet I swayed back and forth. Then I had a chance to try Crest 3D Whitening Strips. I am so happy! It wasn't messy and the results were noticeable after the first use. They didn't burn my gums and whitened gradually so I had no teeth sensitivity that I experienced with other products I tried.

I just want to say that this product is really amazing. I am 46 years young but my smile was definitely showing my age. I was getting very self aware that my smile wasn't what it was in my youth. Years of red wine and coffee had definitely affected my teeth in the worst way. The strips were easy to apply. Wait 30 minutes! It takes a little extra oomph to get them off. And then lightly brush and go. Within 3 days, my smile looks amazing. 17 more to go and it can only get better!

They work well for some moderate discoloration and are good because they don't make my teeth painfully sensitive after using them. They are a little pricey but carry much less of a cost than professional whitening, plus you can conveniently do them at home and in less time without any trays or messy paste.

Love this product for my pearly whites! Easy application process and the strips don't slip off like they used to. Pricey but a great alternative to heading to the Dentist and much cheaper. Would recommend for a super white, looks like you went for a dental appt. smile!

These are great if you can use them for a few weeks and aren't looking for immediate results. They don't taste the best and are annoying to have on but I've found that that is the same for most white strips. I recommend these to anybody that doesn't suffer from tooth sensitivity as they can hurt a bit of you wear them for too long.

I was hoping to achieve a whiter smile with these strips, but I really didn't notice a difference after going through about half a box. The strips were easy to apply, and they stayed in place well, but I did experience some slight sensitivity. That, and not seeing any results was a bummer, so I wouldn't repurchase.

Crest 3D White Luxe Teeth Whitening kit is so worth it! It whitens my teeth and it costs so little compared to what it costs to have done in the dentist's office. These strips get rid of coffee stains and brightens my smile! Well worth it and I love the ease of this at-home treatment!

I know these work to whiten my teeth but I don't think By very much. And it causes a lot of tooth sensitivity in my Opinion. I will continue to purchase because it is a great option for at home teeth whitening I just wish it didn't cause the sensitivity.
