I'd like to thank the product review club for giving me a chance to try this. I've tried many different whitening products in the past and was super excited to try Crest's 2 hour express. Whitening my teeth for 2 hours every 3 months rather than finding time to do it everyday sounded great!

I followed the directions exactly and made sure not to brush my teeth prior to putting them on, and applied them as directed. I found them very comfortable, which was a definite plus since I'd be wearing them for 2 hours. After the first hour i started noticing some tooth sensitivity but i kept them on for the rest of the treatment. Unfortunately after i removed them the throbbing pain became worse and lasted for the next 12 hours. I've used many whitening products and have never experienced this kind of pain.

As for the whitening results, i was really disappointed. I found them to be the same as one application of Crest's regular 3D whitestrips; a little brightening, but not a really noticeable result. After my experience with tooth sensitivity, and the results not being as dramatic as i expected, I'll definitely be sticking to their daily strips instead.

I don't think I'd buy this product in the future or recommend it to anyone. For the price it really doesn't seem worth it.

ok, i was super excited when i got the sample just yesterday
yeah i agree about the extra packaging, but it had four treatments that means it is enough for one whole year
ok
so i gave one to my husband n used one on my self
i was hesitant about two hours as i have a 4 y/o at home but then while using it, time was not a big deal
i had no problems in placing the strips, but yes after 1hr 45 mins i took them off
same goes with my husband (he is a smoker by the way)
it was really hard to pull the strips off
but,
the results were worth it
my teeth r brighter and one shade lighter
as for my smoking husband....he is soooooo happy as his teeth are lighter about 2 or may be 3 shades
now the problem is, he is keeping the remaining two packets for his further treatments :D
ok for sensitivity, i felt a little bit of cold sensations on my lower teeth but that was for 3-4 hours
but for my husband, he had this bad episode of sensitivity overall for about 24 hrs, but now it is subsiding gradually
i believe it will go by the day ends :)
yeah, i think its is expensive to buy yourself, the price should be a little less, n yes one more thing it would have been cherry on the cake if they had provided a shade guide or something like that, will be very helpful in matching the shades (may be im asking alot more :) )
thank u chick advisor for sending me such a wonderful product to try on
i'll be looking forward for more to come
thanks once againg

i just tried the 3D whitestrisps 2HR-express, Well, I was very excited to try this product really, and It didn't let me down...I am very content with the results..To be honest I was expecting something like, dramatically results. which there are not.but the results were good and I really see the whitening so I wasn't disappointed.
to begin 2 hours sounds long, but is really not I put them at noon, while I did other things around the house; I have three kids that kept me busy while I waited....so time wasn't an issue time passed fast!. It was really easy to use nothing complicated just peel, apply and wait, At the beginning the taste is not nice, is a little bitter but not big of a deal. I personally didn't have any sensitivity or ANY DISCOMFORT AT ALL..and when time was up I peeled off the strips and I could see a difference.. my teeth were brighter, and whiter and they also felt cleaner and was happy with the results.Thinking that in just two hours, at home and your teeth are whiter is very good!! And I have to do it every three months which is good.
I didn't tried before any whitening so I couldn't compare it. But this one, worked for me.I would buy it again for sure, I will recommend it to anyone. because is fast, effective, and handy. i would like to add to anyone who try this product that really DO NOT USE RIGHT AFTER BRUSHING' because it really make a difference,in terms of discomfort.
Note: The fact that in 2 hrs. your smile is brighter is great so if you have a date last minute or something like that, you don't have to wait days or go to a professional whitening so for those reasons I believe is worth it!

Thank you ChickAdvisor for giving me the opportunity to try this product. My teeth have never been very bright and I was super excited to try this product.

I remember trying Crest Whitestrips quite a few years ago, and the strips were every had to keep on. Plus it was hard to find time every day to use the product. I love that you only have to use this product once for two hours and the box says the results last for up to 3 months. The box also comes with four treatments so you can have whiter teeth for a whole year.

Putting the strips on was fairly easy, and they stayed on pretty well. My teeth aren't very straight, so I had to make sure I got the strips into all the nooks properly. My teeth are sensitive so it was a little uncomfortable to have the strips on, but not painful. The results are noticable, but not as dramatic as I thought they would be. But I see enough of a difference that makes it worth it. Hopefully they'll whiten more when I try the treatment again in 3 months. I would definitely recommend it to my friends, in fact I picked up a box for my sister already!

I've tried whitening products before, and about 6 months ago I did the Zoom treatment at the dentist. Ouch did that ever sting afterwards. Subsequently my dentist also told me that it was as white as my teeth would get (although I still feel like they could go whiter - insecurities!) The other at home whitening treatments I've done before are always annoying because I forget to apply daily at regular intervals. I also tried those disolving ones before - big mistake.

So I was excited to get to try the Crest 3D White Whitestrips 2 hour express. 2 hours didn't seem so bad, and you only have to do it once every 3 months. So I decided to do it the day I was going to a black tie Gala. I stuck the strips on, and then gave myself a mani and pedi while the strips did their thing.

First off the application: fairly straightforward. I was surprised that they weren't marked top/bottom, as they are different sizes. It's actually pretty obvious which one would be top and bottom, but it always surprises me when companies don't make their instructions idiot proof. Anyways application was super simple - peel it off, stick it on. It had the usual warnings about not putting it on your gums, so I always get nervous and probably apply it a little too low down, but it stuck nonetheless.

Now the waiting game. Turns out 2 hours with whitening strips actually feels like forever. 1 hour was bearable. After an hour and a half (by this time my mani/pedi is totally set and I'm bored) it was starting to get really irritating. Finally the 2 hour mark came - by this point you feel like a drooling, rabid dog, with foam coming out of your mouth from having this sopping wet strip in your mouth for the past 120 minutes. Getting it off wasn't easy, as it sure sticks (in hindsight, bad call on the mani as I had to use my nails to scrape the strip off my teeth); but once you get one corner off, they come off fairly easily.

So overall, the process is very simple, albeit drawn out. But I would rather take 2 hours of saliva-y boredom than a week's worth of repetitive treatments any day!

I had no sensitivity at all during the process. That was until later that evening when I was eating/drinking. I was getting those sensitivity pangs, but nothing compared to the aftershocks from the Zoom treatment. Just the occasional icy feeling inside a tooth. It only lasted for that night and then it was gone.

The results: my teeth are already decently white, but I did notice a difference. As far as using this as a maintenance product, it totally does the job. I don't think the Zoom was worth the pain and cost for the results I received, so this is a way better alternative for me.

A couple of random things that I would have liked to see:

1) package sizing - it comes with 4 treatments (each of which are like a bandaid-sized package), yet comes in the standard big box. Would be nice if it came in a smaller, sleeker box, to make more space in your medicine cabinet. I suppose I could take it out of the box, but I like keeping it together with the instructions.

2) tracking - the instructions say not to use more than once every 3 months. That being said, I thought it would have been useful to leave a little white space on each treatment package, so you could write the next earliest date you can use them (ie. mark off the 3 month intervals on each piece). I wound up writing the date on the inside of the box so that I'll know next time I think about doing the whitening.

Long story short, it's not fun (just because it's gross and drooly and boring), but worth it. I would buy it again.

I was very pleased to get the chance to review Crest 3D White strips 2 hour express from Chick Advisor =D

I have been a teeth whitener for years randomly on and off and have used Crest whitening strips in the passed so I thought that I would be super amazed by this line of whitening strips. As well I had watched quite a few Youtube reviews that were positive so I had fairly high hopes.

This kit is really nice because it comes with 4 whitening treatments so you aren't just forking out a bunch of money for one use, it lasts a year so I think it's really good for the price.
I found these very easy to apply, they are very similar to the other Crest strips but they are slightly thicker and extremely sticky! I didn't realize how sticky they were until I was removing them.

When applying, start with the bottom strip first, then move to top. Once strips are applied you wait 2 hours.
I did have a few times where I thought they were slipping off but they weren't . The strips were slightly annoying to wear for 2 hours straight but I mean its worth it if you get whiter teeth right?
I was able to drink some water and talk fairly okay while having these on.

Once the time is up, I went to pull the strips off but they were so stuck on my teeth I couldn't just slide them off like the other Crest strips I have used. Which is good so you know they are stuck on for the 2 hour time frame.
I had slight pain in ONE tooth but I didn't think too much of it, I brushed my teeth with Sensodyne tooth paste and I was able to drink room temperature water.

The results were really good! I do not have super yellow teeth to begin with but they needed some freshening up and I was happy with the outcome, I was actually a little shocked at first at how white they were!

So at that point I was happy!

Now for the negative =/

I went to sleep that night, I had used the strips in the evening and went to bed a couple hours after using it, I woke up in the WORST teeth pain in my life! I seriously thought my teeth were going to explode and shatter! I really do not have much sensitivity problems ever, the odd time I have some noticeable sensitivity after too much whitening but never ever ever from one use or this excruciating. I have a good pain tolerance but this was brutal. I didn't sleep at all that night, at around 1 am I found myself googling what to do when you have this problem but nothing ever was found. In the am before work I stopped by Shoppers Drug Mart and purchased some Orjel to temporarily numb any pain I could. This did not take away much pain, my 9 hour work day was the worst day I have ever had from this pain. It has been 25 hours since I have used this and I still have a fair amount of pain.

I will never use this product again, I am going to give the left over away to a friend who likes to whiten her teeth and hope she does not run into this problem.

So I DO NOT recommend this to anyone who has sensitivity issues at ALL!!! Save yourself from this pain, it is not worth it.

If you do not have problems with sensitivity I say go for it! If I had no pain I would purchase this product as well recommend it.

First off I would like to thank Chick Advisors for choosing me to test the Crest 3D White Whitestrips.

My overall experience was okay...I guess I was expecting miracles from these strips...but they did a below average job...I guess if your teeth are slightly discoloured they would work perfectly for you...my teeth needed a little more help...now maybe if I keep using the product I would see way better results...I've only been using them for 7 days...and see minimal results...

Compared to other products its not bad...it takes a little getting used to having them in my mouth...they feel quite odd...I would rather have a product that goes on and comes off more quickly...time is of the essence...as a mom of 3 time is very precious...

I probably wouldn't buy this in the future...the cost is expensive and the results aren't as great as I wished...I would only recommend it to a friend who's teeth need a little help...

I was chosen to try the crest 3d white whitestrips 2 hour express. When I got chosen I was really excited because I have never tried any teeth whitening products before. But I became dissappointed after trying this product. My teeth became a bit whiter but not as much as I hoped or assumed they would. I left them on for the 2 hours, but close to the end my teeth were starting to hurt. And it was quite a few hours later before I could take a cold drink or eat. But the pain and sensitivity did eventually go away. I unfortunately though don't think that I would recommend this product.

I just finished using the Crest Whitestrips (2 hours) and I'm not impressed at all. I hadn't ever tried a whitening product before. If you had already whitened your teeth and wanted a touchup, then this product might be right up your alley. I actually gave up and threw out the first set of strips. They weren't comfortable at all. So I tried again and just put up with the discomfort. I'm not sold on this product at all and I don't think that I will tell anyone I know to use it either. I would have been upset had I paid for the Crest Whitestrips. The only plus side for me was that my teeth feel cleaner!

I recently received the Crest 3D White Whitestrips 2-hour Express teeth whitening kit to try from ChickAdivsor. As I have never tried a teeth whitening kit before, and was looking to whiten my teeth, I dedicated a few hours during my downtime to test the product.

The enclosed instructions were fairly easy to follow, and I did not experience any extradordinary trouble with the application of the strips. I enjoyed the fact that I only had to dedicate two hours or so to the task as opposed to days or even weeks as required with other teeth whitening kits available in the market. This was perhaps the most important feature of this product for me.

I did not experience uncomfortable or unbearable teeth sensitivity while using the strips, just a slight sensation that was tolerable and went away a few hours later. As my teeth were "non-white" due to my coffee consumption, I was looking forward to whitening results. After using the Crest 3D White Whitestrips 2-hour Express kit, my teeth are a few shades whiter, not bright white but definately improved from what I started out with. The kit gave me naturally looking noticable whiter teeth, but as I stated above, not bright white.

I would recommend the Crest 3D White Whitestrips 2-hour Express kit to those who would like to whiten their teeth a few shades without the longterm commitment required by other whtening kits, and to those who do not want to pay high dentist fees to have it done.

Overall, a good product with time-saving benefits.
