I was very excited to test this product out as I had previously used the white strips which you leave on for a half hour for X amount of days, for me the hardest part of those was actually remembering to make it a routine for a period of time, so when this product came out and promised whiter teeth within 2 hrs, I was definitely excited!

The product for me, did what it promised, it whitened my teeth about 2 shades within the 2 hours, and now they are bright and white!

I experienced some sensitivity but that is because I have sensitive teeth to begin with - so this was expected! I do not believe these caused my teeth to be more sensitive than any other whitening product that I have previously tried.

The only downside to this product is the 2 hr wait time for use - HOWEVER I did put them on and take a nap to try and make that 2 hr wait as painless as possible, and it worked. Thank you Crest for living up to your usual expectations and I look forward to continued use of this product!

I've previously used other Crest White Strips where you wear them for 30 mins for a few days. My teeth did look whiter at the end of the treatments. I guess for these ones the 30 mins over a few days are crammed into 2 hrs in one day. Unfortunately I didn't really see much of a difference. They might be a little whiter but that could be me just hoping it's working. Even if they are a little whiter it's not that significant.

I do have sensitive teeth and after removing the strips my teeth are sensitive. I have had this with previous white strips as well so I expected it to happen. The sensitivity didn't start until after I removed the strips though. White the strips are on I didn't feel any discomfort.

Another aspect that I didn't like about these strips are that you have to wear them for 2 hours. That's a long time. I had to find the appropriate time period to where them. I kinda prefer the shorter time period over a few days because it's easier for me to find 30 mins a day as opposed to 2 hours.

Overall I probably wouldn't by this product again. I didn't get really great results and it's pretty expensive. The package is also for a whole year which is a long time. You might lose them in that time frame.

I was super excited to be selected to try the Crest 2 hour whitestrips. I had been seeing a lot of commercials for this and was curious how well they would work. I had previously tried the 20 minute type of whitestrips before that did not really do anything and figured the 2 hour version must be more potent... well, it's not!

The good news is that there's no irritation and you get the usual increaed saliva production once you put them in. They're easy to apply and easily cover my teeth.

The downside is that the 2 hours takes forever to go by and I was super thirsty by the time my timer beeped. The other obvious downside is that I did not see a difference at all in my tooth color. I was hoping for a bit of a brigthening/whitening, but it really didn't do anything for me. I don't plan to purchase this once I'm done this trial.

Thank you for the opportunity to try these White strips! I have never whitened my teeth so was really looking forward to trying them. They were very easy to apply and stayed on for the 2 hours. I have to say though that I was disappointed in the results. I was expecting to notice a big difference in appearance but really did not see any significant one. My husband said my teeth looked brighter! I normally have sensitive teeth so was worried they would be more so but did not notice any. I thought it would have a taste but nothing so that is good. Now I can't wait to try them again in 3 months to see if there is any change.I think the price is a bit high but overall this is a very convenient product and super easy to use.

I received the Crest 3D white whitestrips 2 hour express in the mail as a product tester. The packaging was small and attractive. Inside were 4 foil wrappers. This box is meant to last you one year. Every three months you use one package to retain your "white teeth". Inside each foil wrapper is a bottom and upper teeth strip. Very simple and easy to use just place on the teeth, hold for a few seconds and fold over, so that it can stay in place. For the two hours that I had it on it did not move. There was no taste at all, no chemical or peroxide leaching out, which was so nice. Didn't even seem to mind them on at all, only thing is that it makes you salivate just a little bit more. Also there was no burning or gum pain. Easily a very neat product. You just peel it off your teeth when it is done and I just had to rinse them with water to remove any whitener still on them. My teeth did lighten up a shade for sure. My hubby said he could see a difference. I definitely would recommend this product. Very happy with the job that it did. I would say that for the cost of the product and it lasting you a year worth of treatments, its a great buy.

Thanks for this great opportunity.

I try the whitesrips and I loved it!

Easy to apply and they stay in place.

Great result! Easy to use!!

My teeth was whiter!

Nothing negative to say about this product!

I will recommend it to my family and friends. I will buy this strips in the future for sure!

Thanks again for this opportunity.

I had tried some white strips a few years ago when they first came out. So was interested in seeing if they had changed much. I have to say that they did stay on my teeth better than they used to and that there wasn't such a strong taste. I wish I had taken before and after photos as after the application I didn't notice any difference. I thought that I would see a bigger difference but unfortunately there wasn't. If I was to purchase white strips in the future I think I would spend a little more money and get the Advanced Vivid.

I've whitened my teeth before, and usually it involves multiple applications over several days to see results, so this 2-hour express version is certainly more convenient. The strips are easy to apply, and not too troublesome to wear (my mouth felt a little dry, but nothing you can't manage.)

Though I didn't do before and after shots, I'd say my teeth were whiter. Unfortunately they were also far more sensitive. My lower teeth actually ached for the rest of the day. I don't normally have sensitive teeth, but this was apparently a bit much for my pearly whites. While I love that I wouldn't have to do it again for 3 months, I'm not sure it will be worth the mouth pain. I might have to switch up for the sensitive teeth version.

I received this as part of the product review club:

I am pleased with this product in general. As for an alternative to going to a specialist and paying hundreds of dollars, this is one of the more effective home whitening kits.

I was slightly nervous at first to apply the strips as my teeth are not perfectly straight, and I've had difficulty with stripe like products before not completely covering my teeth. The size of the crest white stripes were a little more accomodating.

I liked the idea of having to only wear the strips for 2 hours every three months, this is way more likely to actually happen then something you'd have to apply nightly for example.


My teeth were slightly sensitive after the first use, which could have been my application technique, I will find out with my second trial, but I did notice a difference in colouration, and was impressed that I saw a slight difference in only 2 hours!



(as per suggestion from Chick advisor, the box was dented when arrived, and I didn't get a glimpse at the delivery guy ;) )

I was one of the lucky you that got to try the crest 3-d white whitestrips 2 hours express. It was the first time that I was trying something like that. I was very surprise of how easy it is to use it. I tried it over the week-end and I would recommand it.

I'm not sure if my teeth went so much whiter but I could see them more bright then before.

Overall i was very satisfied and i'm happy i have some more for the rest of the year.
