When I quit smoking I tried everything To get rid of cigarettes stains. Even with regular dental visit and cleanings the stains remained. I tried all kinds of Tothpaste. No help. After 5 packets the Stains are almost gone. I still have several to use and another box. Thanks

Crest 3D whitening strips are easy to use and works really well. After about a weeks worth, you could start to see the difference. Although it did not give me sensitivity, some of my friends did get some sensitivity, so be aware of the pros and cons of it. Overall very good produce and would recommend it!

[This review was collected as part of a promotion.] Crest 3D Whitestrips Rapid Smile Makeover: Dazzling smile. I have tried these teeth whitening strips and they are very good, the package has 10 packets of strips for the teeth, each package has 2 strips for the upper and lower part of the teeth, I started using them and the first unpleasant thing is the first seconds when I put them on the taste feels horrible like bitter, then it feels normal, they are very easy to install and very safe and comforting, they do not fall off easily, I can drink liquids even with them on, I just let them act according to the instructions for 60 minutes and then remove. After using them I do feel a little sensitive in my teeth but it is normal then as the minutes go by it disappears and the truth is worth it, I feel that these strips are effective and worth it. Perfect for the price.

I am so happy that Crest Whitestrips 3D Professional Effects exist! They whitened my teeth quickly, without pain, and removed stains I have had for a very long time. I will continue buying and using them as needed, and highly recommend them! They also make my boyfriend more kissable (but don't tell him!) Julie from Glendale AZ

These strips are AMAZING! They stick to your teeth and do not fall off when you talk, like other brands. It only takes thirty minutes and I could tell the difference in just the first use! The first time that I bought them, I used them every other day for about two weeks. My teeth have stayed very white. I drink coffee everyday, so naturally they will get a surface stain from that, but with one use of these white strips, my teeth are perfectly white again! I would recommend these to anyone looking for a great whitening product. They are a bit pricey, but definitely worth every penny!

[This review was collected as part of a promotion.] In the package, there are 11 whitening strips, and I used the product for 11 days. I appreciated the comfort of the strips. They are easy to apply to the teeth. They need to be left on for 1 hour. Sometimes, I felt a slight sensitivity in my teeth and gums, but it didn't cause me any discomfort. The strips adhere quite well to the teeth, so I cleaned off the remaining gel and adhesive with a toothbrush and toothpaste. After using all the strips, I really noticed that my teeth had become one shade whiter, and I felt their effectiveness. This was my first experience using whitening strips, and I am very pleased with the result! I think these strips offer great value for anyone looking to whiten their teeth by 1-2 shades at home.

I am disappointed with the quality because there is no expiration date included on this product. They package the individual strip packets in a cardboard box and the strips nor the box have the expiration date. I will need to return these for a full refund because they do not work if they are past the expiration date and there is no way of knowing.

It's so amazing, that it really works. I am soon 24-year-old and I have had since childhood yellow teeth. I don't smoke but i drink coffee and sometimes but rarely red wine. I have a healthy lifestyle. I was really skeptic and sure that doesn't do anything to my teeth. But I want it to try, so I used 7 strips half of the year. Now i can see in the mirror and photos that my teeth is naturally white and I have lot of confidence to smile too. Enamel is not damaged and doesn't feel uncomfortable, they also stay place. salivary flow was strong with the strips. I will use them again. I can warmly recommend, be surprised positively!

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.

Over the years I have tried countless whitening products, but was always left disappointed. I had always been a little skeptical about Crest Whitening Strips, kind of like one of those "too good to be true" kind of things. Until one evening when I thought I would just give the whitening thing one last try. After the first two nights I was astonished by the results. Not only did I notice the immense difference in my smile, so did my friends and colleagues. I have never felt more confident in my smile. I might even dare to say it is absolutely flawless. Crest Whitening Strips not only turned my average white teeth into an impeccable smile, but it also gave me the confidence to walk around everyday flaunt my smile. In my book, you can't put a price tag on feeling beautiful and confident. Even if you had to, I'd say these are a steal.
