A few points about this product:

It works! Really. My teeth are most definately more white after completing the 7 day treatment.

The only drawback? It took more than 7 days. My teeth are slightly sensitive normally, so by the third day of treatment I had to skip a day. That being said, I finished up the last 4 days with no more sensitivity and my teeth now look great!

Thanks Crest!!

One word to describe it is amazing ..product works wonders for me on the second day. And on the 7day of using it my teeth were pearly white.the price on the other hand is a little in the steeper side however because the product worked so well I would repurchase it. Thank you chick advisor for sending the product for me to review.

I was one of the lucky people given the opportunity to try out the Crest 3D White Whitestrips Intensive Professional Effects. So I received the strips just over a week ago and started using them on the Saturday morning. You have to keep the strips on for 2 hours so it's a bit of planning so you don't eat or drink anything for that amount of time. Or talk. During the two hours of having the strips on every time I spoke my fiancée snickered as I was talking with a distinctive speech impediment from trying to keep the strips on my teeth. I shouldn't have worried. These strips were a bit different from the ones I remember from years ago. Those were more like saran wrap that were slimy on the inside and slipped around a lot. When I had to remove these ones after the two hours they were amazingly suctioned on. It actually took some pulling to get them off. Good to know so next time I'll be able to talk normally.

After taking the strips off my teeth were remarkably whiter. Pretty impressed. They looked great and I didn't feel anything... then. About 6 or 7 hours later I felt some sensitivity. Not the worst I've felt when using whitening products but my teeth were not the happiest in the world. But they were definitely quite a bit whiter which was awesome as the next day was my engagement shoot. So the sensitivity lasted about 12 hours or so. Never incredibly painful, just kinda always there. I decided to give my teeth a couple of days to recover so the next time I used the strips was a few days later. I did some research and learned about some flouride toothpastes that can help with the tenderness. I ended up buying and using Cirpo 5000 before trying my second strip. I used the strip on the Tuesday morning so it had been a couple of days in between to give my teeth a break. After removing them this time my teeth were definitely whiter but not as much of a dramatic change as the first strip. My teeth didn't hurt at all until a few hours later (I'm guessing there is some numbing agent inside the strips) but this time they didn't hurt nearly as much and the sensitivity only lasted a couple of hours.

I again gave myself a couple of days in between the strips to use the fluoride toothpaste and used another strip on the Thursday morning. Same routine, kept them on for two hours, yanked them off to see whiter teeth. Again a little sensitivity but looking pretty darn white now. I used the fourth strip this morning (Sunday) with the same routine. And to be honest I'm not going to use the remaining three right away as I don't think my teeth are going to get any whiter. They look pretty awesome if I do say so myself. I think I'll save the remaining three for a touchup before my wedding.

So the bottom line is that the strips work very well. It's a bit of a commitment with the two hour strip on time but the whitening is pretty drastic. Very impressed with how well they stay on. My only complaint would be the sensitivity, but it is manageable if you use the fluoride.

i was worried this may cause sensitivity since you have to wear them for 2 hours a day but it was surprisingly painless and there wasn't a lot of bad taste after using this for 3 days i noticed a difference buy the end of the week my teeth were very bright i would recommend buying this for sure !!!

These worked great! After using these strips 3 times, I could already see results. My gums are a bit sensitive so they did burn the first time, but after that I couldn't really tell. Overall, I'm very satisfied with them, and would definitely buy them again. They are however, a bit pricey but still worth it.

First off I want to say that I received these free to try as a member of the ChickAdvisor Club.

I was super excited to be selected for these as I've been looking for something to help whiten my teeth....due to my tea and coffee drinking :S After reading the directions I was a little bummed to see that the strips were supposed to be left on for 2 hours. Anyway.....on went my first set of strips....and I waited....and waited...and waited....and after 2 very long hours I took them off. I will say that the strips stuck to my teeth much better than others I've tried in the past. They also didn't taste nearly as bad as usual....which is a bonus since you need to leave them on for so long.

I didn't notice an immediate difference and went to bed the first night only to wake up with a beyond ridiculous toothache....is every single one of my teeth! It was so bad that I couldn't get back to sleep and had to take 2 Advil which unfortunately didn't seem to take any of the edge off. The pain lasted for about 3 days and I could barely eat or drink anything. Needless to say the first day I tried these was my last day.

Overall, the product seemed to stick on my teeth really well.....and didn't have a bad taste....but I didn't get to use them long enough to see any results. It's likely worth a shot for people who have never had a sensitivity issue.....but for those that have....watch out :s

I was quite impressed with these Crest 3D Whitestrips. I had no problems with the application or removal. On day 3 I experienced mild tooth sensitivity,so I skipped a day then continued on with the remainder of the stripe. I will definitely purchase Crest 3D White strips in 6 months time to give my smile an instant makeover. Thanks so very much for allowing me the chance to try this product

I found them to be amazing and how clean my teeth feels afterwards. It is the next best thing then going to a dentist. It definitely whitened my teeth and made them brighter. The price is on the costly side but I do get coupons for them and as long as they were on sale too then I would buy them. I would recommend them to my friends and family for sure!

I got these as a part of Chick Advisor Review Club and I was pretty excited to start using them.

Pros: They did noticeably whiten my teeth.

Cons: I had a great deal of sensitivity so much so that I started doing the treatments every other day. 2 hours was a super long time to keep them on my teeth. I didn't like how much they foamed up in my mouth. It says that you should be able to drink water and what not while wearing them, but I wouldn't in fear of them slipping off and swallowing them.

Over all they did what they said they would do. I wouldn't purchase them again just because they are out of my price range.

I was very fortunate to be selected to review this product for ChickAdvisor. The retail price can certainly deter someone from getting these but it may be worth it. The strips are easy to use but due to time, I was not able to leave it on for the full 2 hours as instructed.

The first few days that I used the strips, I did feel more sensitivity than I usually do. But even for the time that I did keep it on, I did see a difference in the colour of my teeth. If you are one to get your teeth professionally whitened, this can save you some money!
