Crest 3D Whitestrips Intensive Professional Effects worked well & did what it claimed. It did whiten my teeth, however, i used it over 14 days. My teeth are a couple of shades whiter, and i did experience some sensitivity (which is normal). They adhered well and peeled off rather easily. it's great that they stay put & don't move around like some other products i have tried in the past.

2 hours is a long time to keep them on, but if you are diligent & follow the instructions, the whitening is effective & noticible.

i would recommend them to others, but the price is a little high ($69.99 retail) for regular maintenance after initial use.

i thank chickadvisor for providing me with the opportunity to test them! my smile thanks you too! :D

I was very excited to try this product, however only recieved average whitening. My teeth were a bit whiter ( not a huge difference though ) and felt very clean. I did experience tooth sensitivity to the product so used it every second day instead of everyday ( maybe that is why the effect was not as good ). I am very busy and honestly finding 2 hrs to sit with teeth whitening strips on a day for a week ( or in my case 14 days) was very hard, I know people say you can do other things with them on but it was still hard haha! They did stay in place really well which surprised me I was expecting them to move around and slide off, but I almost had to peel them off :) Overall I think these are a good product even though they did not whiten my teeth as much as I was hopeing I will likely try them again in the future.

I was very excited when I received the product. It was definitely easy to use, worked very quickly and gave me a nice bright smile! It definitely beat the toothpastes like Sensodyne that state that they make your teeth whiter! I felt a little discomfort with regards to the sensitivity... Never felt like that before.

Overall a good product and a great buy for the price!

I was really excited to try out Crest 3D White Whitestrips Intensive Professional Effects because I recently quit smoking so I wanted to whiten my teeth. I have used regular whitestrips in the past, but I have never tried any of their stronger treatments. The first night I used the strips without a problem, but the second night I experienced extreme sensitivity so I decided to take a night off of treatment. I used the third strip but unfortunately experienced the same level of sensitivity that I decided to take the strip off. I have not yet completed the treatment because I personally need a longer period of time to get over the sensitivity.

My teeth are slightly whiter, but in my case I'm not sure I will get the full effects of the treatment. For the price, I think that it is a really good starting point for someone who has mild staining but does not want to spend the money at the dentist office.

These work very well, although they caused my teeth to be very sensitive afterwards which I have never had before, even though I have been using Whitestrips for 8 years now.

The product works well - there's no doubt about that. I saw the difference in my teeth immediately. However it is very uncomfortable to wear and I hate the residue that comes with it.

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.

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.

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!
