Was very excited to receive my Crest Whites Strips and was ever more ecstatic with the outcome. I’m a huge sceptic at heart but love when products prove me wrong. Huge advertising ads state that Crest White Strips have improved to the extent of whitening teeth in two hours. My thoughts...IMPOSSIBLE.

So I pried open the box, read the instructions and waited 2 hours for the results. A hour and a half into the process I noted that a tooth became a little sensitive. I panicked at first and reverted back to the instructions which does state that there may be some tooth sensitivity but would subside after some time.

5,4,3,2,1........

*Sound of the buzzer goes off in the background*

I forgot to mention in the onset that prior to using the strips; I took a picture with my phone so that I would be able to compare the difference....if any. To my surprise there was a remarkable difference. My teeth were WHITE. I was very happy with the results. I went out for dinner the next day and a random girl stopped me to tell me how she loved my smile and wished her teeth were as white as mine (no word of a lie), I thanked her for the compliment. I wanted to take credit for it but I did mention to her what I had used the night before.

Oh and one last thing, there are only 4 treatments per box. I don’t know if its because that is how long the results would last but stay tuned..............

I received the product for review from the Product Review Club. I have used several other whitening products (toothpastes, and trays) with a some success. But I found myself avoiding it due to the horrible taste it left in my mouth. The Crest 3D Whitestrips I found were very comfortable and did not leak any product. I was quite comfortable to leave them on my teeth for the entire two hours.

After taking the strips off I did notice a little sensitivity on my bottom teeth, but that went away in a couple of hours.

One thing I thought was great was that the box is supposed to last you for ONE YEAR. I thought that made the price of the product easier to comprehend.

Overall I would recommend this product due to the ease of use, and whitening results it gave.

I have tried a few other teeth whitening products, first off, Crest 3D White Whitestrips 2-hour Express stays on better than similar products. There was a noticeable bit of whitening which was great. The downside, with that came some tooth sensitivity even though I use toothpaste for sensitive teeth. Would I use again? Probably but once in while for a quick sparkle before an event.

Great product!!!!!! Really does whiten in 2 hours, not messy at all! Was better than the other products I have tried in the past!!! Really like the 2 hour whitening feature, saves time and you see results quickly!!!!!!! Innovative!!!!!!!!!

I was excited to try the Crest 3D White Strips. Often times when I want to spiff up my teeth I don't have a long leeway time before a special event/occasion so I was happy these were to work in only 2 hours. However, I was unhappy with the burning sensation I got from wearing the strips. I could only have them on for about 1 hour and 40 minutes before my gums were burning too bad to keep them on any longer. I didn't find it made much improvement but perhaps that is because I could not keep the strips on for the full 2 hours.

My preference is to use Crest whitening toothpaste on a daily basis versus the strips.

i have used the crest Whitestrip before and I am very impressed with the 2 hour strip. it is not uncomfortable- i thought it would be and besides making my gums a little sensitive, i have no complaints and my teeth are quite noticeably whiter. Thank you for including me as one of the testers.

This product was great for brightening teeth.I drink a lot of coffee and red wine so i could notice a dullness in the color of my teeth. After using crest 3d 2 hr express there was quite a difference in the brightness of my teeth, however color change was about 2 shades difference,which is great for a 2 hour product. It caused some sensitivity but that went away by the next morning.This would be something i would recommend and in fact i already have!

I was lucky to receive yet another product to test and review. I was excited to try this product because I have previously tried the regular Crest Whitestrips (which produced great results but brought on sensitivity and were very uncomfortable to have on). The quality of the strip was really good in that it held on very well and I did not really feel the taste of the product in my mouth for the duration of the time it was on. Taking it off was not very pleasant, as chunks of the product stayed on my teeth even after removing the strips. It took some harsher brushing to do so but eventually I removed it all. I did notice a difference right away, and was pleasantly surprised that a 2 hour product can do so. After reading others' reviews, I was worried that I would have sensitivity as soon as I removed it or the following day, however the sensitivity the day of was very minor and there was no sensitivity the following day (I usually have sensitive teeth & gums). Although my teeth do seem whiter, it is more of a brightening effect and not so much of a noticeable wow factor. I think this product is nice to use for that reason, but if one is looking for real whitening, I would say this is not the product to go for. I will most likely try and use the remaining strips in the box within the year to see if the whitening could get better but I probably will not buy this product.

I got these strips through Chickadvisor product review.

My teeth were in the end about 2 shades whiter....not excessively white. It was ok to talk with in my mouth. The only downside was my teeth were sensitive right after til the next day. But is worth it, considering how much dentists charge. Though I Wish my teeth were whiter than they turned out.

I recieved this product from the review club a little later than everyone else and I was excited to try it but I ended up not being able to find the time considering it requires 2 hours to do its job.
I used it after I put my kids to bed over this weekend for the first time.The instructions were easy to follow and after sticking them on you can pretty much carry on with your day. At first I found the taste and the tingling on my tongue irritating. I havent used any other whitening products recently so perhaps im just not accustomed to the sensation and taste. After a half hour the bitter taste turned sweet which was more pleasant.
An hour in I could hardly wait to take them off and sleep but because I still had an hour left I decided that I would set my alarm to go off in an hour and I fell asleep.
Two hours in, as I was peeling off the strips, they were still stuck on pretty good which was surprising but the end result was very disappointing.There were a few white spots on my teeth after the treatment but I didnt notice any overall visible change. The following morning the spots were gone.
As for tooth sensitivity, I had no discomfort the night of using the whitestrips but the following morning I noticed my teeth were especially sensitive. I didnt expect any miracles before I tried this product but I did expect it to do more than leave a few random white spots. This product is time consuming and left no desirable results, I will not be purchasing in the future.
