Why spend big bucks going to a dentists office for whitening when you can get great results from the Crest 3D White Whitestrips Professional Effects? I tried them and received instant results that were amazing. I'm 69 years old and the lifetime of stains disappeared quickly, and completely. This product is outstanding.

I do see a difference when I use this product. My teeth do appear whiter. However I have sensitive teeth so I use the sensitive option. I do find sometimes they don't stick on my teeth right away. I have to wipe my teeth so they aren't too wet and then they stick just fine

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!

This is just as good as a professional teeth whitening! I used this 15 years ago and to this day I've always been told how white my teeth are! That's how good it is! I only maintain by using whitening toothpaste. When using the strips it can leave you with some sensitivity so you can use Sensodyne while you're using the strips. If I ever need a touch up I'll definitely buy this one again! Crest 3D White Luxe Professional Effects Whitestrips - Teeth Whitening Kit

This product makes me want to smile all day because of my white glistening teeth! I love this product and unlike some other brands, it doesn't leave a grainy feeling on your teeth! Would totally recommend this product to you guys right before getting pictures make or just to feel more confident I your smile!

I started using the whitestrips a few months back and loved the results. Everyone noticed the difference and gave me compliments all the time. I did have sensitivity but just went from using everyday to every other day to once a week. Once my teeth were as white as I liked it was fine to only use them once a week to maintain. My sister was a bit jealous of my results since we were always known as twins even though we are a few years apart we look so much alike. Our teeth on the other hand were now very different. I gave her just three strips to use and now she has purchased her first box. We are now both lifetime costumers. Thank you so much Crest for a great product!

This made my teeth so unbelievably white! It was a little expensive, but you definitely get what you paid for. I have used this product once a year for quite a few years now. The only complaint I have is that it makes my teeth and gums very sensitive. Other than that, I love this.

I purchased a small package of these whitening strips a while back and really enjoyed them. The pack came with 7 strips to use for one full week. I spaced them out over a much longer period of time to avoid making my teeth too sensitive but they still made a very big difference. I definitely plan on purchasing more in the future to keep my teeth pearly white!

They work but are expensive. But at least I can use them intermittently and when needed a few times versus just one time expensive teeth whitening. I'm not sold on the shape because they are straight at the top and would prefer a slight curve to fit the teeth better. I use them and don't see a remarkable difference like in office whitening, but they do work and are more affordable.
