I was selected to review this product. Had I not been selected I may not have bought it on my own as the price would be too much... But on to the review.
I had a 2 hour drive to do so I thought it would be a great time to use the Whitestrips. I didn't feel much of a tingling sensation until right after I took the strips off. Now, 4 hours after the treatment, I'm feeling a bit more tingling but it is very bearable and its the price you pay for having white teeth that only took 2 hours, woohoo.
I don't normally experience sensitivity so I'm hoping that this treatment won't trigger any.
I have previously used the whitestrips that you use once or twice a day and this was very similar except that it was for 2 hours and I only had to do it once.
My teeth do look whiter and I would use this product again.

I was given this product for review, otherwise I probably wouldn't have bought it. I'm not a big fan of whitening strips after some pretty bad experiences in the past - burning, foaming... remember those days??

The good news is: those days are over. I expected at least a little foaming, but nothing. I kept them in for two hours, as per the directions, and not so much as excess spit. I was pretty pleased with that.

Definitely easy to apply. The instructions are pretty clear and the strips don't budge once they're in place. I put them on before bed, when I knew I wouldn't have to interact with a lot of people - just in case, I didn't want to look like a rabid dog.

After 2 hours they were easy to remove. I wasn't sure if I was suppose to brush my teeth (the instructions don't say), so I just rinsed my mouth. There was no weird taste or feeling left on my teeth, which I was pleasantly surprised with.

I didn't notice any difference right away, but I am pretty sure they lightened my teeth a shade or two. I may be also trying to convince myself there is a difference.

PROS
- cheaper than dentist whitening
- easy to apply
- no taste or residue left behind
- no foaming or burning while on teeth

CONS
- definitely teeth sensitivity over the next two days, but it went away
- two hours feels like a VERY long time, especially if you're hungry

I was chosen to test this product and my overall experience using this product was a great experience. I have not tried any whitening treatments in the past so I thought that this product was very effective in brightening up my smile. Its very easy to do and you only have to do it every three months which is great! The only drawback is some tooth sensitivity for a few hours after using this. But, I do like this product and have definately told my friends to try this. Thanks Chickadvisor!

What was your overall experience with this product? (eg. using the product, final results, etc)

I received this product to test, and it just may be my favourite whitening product out there! I'm the kind of person that wants to see instant results, and this give you that! I've used other whitening product before in the past, and they were alright, a lot of slip and slide, whole mouth watery, saliva dripping etc etc. THIS stayed in place, and i didn't have to worry about this whole "can i swallow my saliva" thought. It's easy to stick on, theres photos for those who dont understand. You leave it for 2 hours, you can go watch tv or use the computer (trust me time flies). and when you peel it off, i can feel a layer was coming off. Instantly your teeth is brighter, and not as yellow!

In short:
-stays put in your mouth
-instant results
-dont have to debate if you can swallow your saliva, as you wont have any issues.
-SIMPLE
-you only have to do this 4x a year!

i'm definitely going to recommend this to EVERYONE!
Thanks for picking me to review it!

I received this through Chick Advisor's product review club. I have tried other crest white strips in the past and was excited to try their 2hr whitening version.

Positives:
- Follow the instructions and you'll be fine
- Effects last for 3 months (one little box for a whole year's supply, easy to store so you won't lose them)
- They stay in place and don't slide around
- Yes it's a painful 2 hour process, but if you do it while doing an activity the time goes by quickly
- The results were noticeable white. My teeth are pretty white to begin with but I was very satisfied with the extra bright smile I was left with.

Drawbacks:
- My teeth had a discomfort, a tingling sensation that lasted long after I removed them from my teeth. In the instructions however there was a disclaimer that if you do experience discomfort they have a sensitive version that's less harsh


If you know your teeth are sensitive I suggest trying the sensitive version because the results with these were great. If you want to try to see if you'll get a discomfort, go for it, as the results were great!

I was chosen as a tester for this and I have to tell you I was so excited! I have used Crest White Strips int he past but never the 2 hour one. It's fantastic! I love that it had enough in the box for a whole year's worth and I only have to use it every three months to maintain my beautiful whiter smile! Thanks to Crest this is a great product! I will definitely be buying this again next year!

Through the product review club I received a box of the Crest 3D Whitestrips 2-hour Express. I followed the directions and applied the strips to my teeth (and my husbands). I really do prefer the advanced seal system versus the regular "keep sliding off my teeth" system. They adhere very well and this is an important feature if you are to leave them on for a 2 hour period.

At around the 1 hour mark both myself and my husband started to have tooth sensitivity. A dull ache that wouldn't let up. At that point I really wasn't sure if I felt comfortable leaving them on for another hour. Both of us persevered until we reached the 2 hour mark.

We were both satisfied with the end results. Our teeth were visibly whiter and brighter. However, we both continued to have tooth sensitivity into the next day. We are now using a toothpaste marketed for tooth sensitivity to try and reverse the pain.

Verdict: Although the strips provided great whitening powers we did not feel that the pain was worth the results. I will stick to the regular Crest Whitestrips which do not cause the same level of tooth sensitivity and provide similar results.

After using both the two week cycle and one week cycle of Whitestrips in past years, I was excited to try this new two- hour version. Having to use these prior for such long amounts of time left my teeth feeling ultra-sensitive and sore, so my hope was that by using these for only two hours, it wouldn't be that bad, right? Wrong! Although I am happy with the results (my teeth look a lot brighter), the process was painful. My teeth felt very sore, even the next day! I did appreciate how easy they were to use and that they stayed in place once put on my teeth. I am also happy with the results. My teeth weren't too stained, so were fairly white when I started, but I did notcie that there was an extra brightness in my smile. Can't go wrong with that, right? Just be warned that if you try these, chances are you will be in pain. I guess that's the price of beauty :)

Wonderful Product, easy and fast to use, well worth the 2 hrs...

First I would like to thank Chick Advisor for this amazing product testing opportunity!

I was so excited about testing this product that I did it the same evening that it arrived. I was concerned about 2hrs with these strips on -- what if the phone rang or someone came to the door? The last time I whitened my teeth I used the bleaching trays and you couldn't open your mouth to talk or anything! These strips were amazing and yes, someone did come to the door but luckily didn't notice anything. They are so comfortable and talking is not a problem which is nice because trying to find 2hrs of uninterrupted time in my house is impossible!

As for the product, I did experience some teeth sensitivity for about 18hrs after using but it went away and was absolutely worth it when I saw the result. Although I didn't have any stains on my teeth the results were noticeable in their brightness! I LOVED this product so much I lent one set of strips to my Uncle who had very badly stained teeth and then OMG what a difference - wish I'd taken a photo to post because the results were unbelievable and in only one treatment!

I have told everyone I know about this product and again would like to thank Chick Advisor for this opportunity!!!
