I found this product worked but not as well as expected. I was hoping for a few shades lighter although it did whiten my teeth. The ads for this product make you believe it will be a drastic change but in actuality it only whitens a shade or two lighter. I would purchase this product but I am inclined to try other products to see if they will work better.

I was excited to try these new strips and was hoping for better results than the other products currently on the market give you. However, I was pretty disappointed over all.

The strips were very easy to apply and stayed in place the entire two hours which was great. I was able to go about my morning and carry on normal conversations without sounding like I have something in my mouth or having the strips move around.

When the two hours was up I was anxious to see the results. Well, the whitening was pretty minimal. I've had much better results with the more affordable (and admittedly less convenient daily strips).

Twelve hours later the tooth sensitively that began as just a slight tingling is only getting worse (and I don't have sensitive teeth).

Bottom line, for me, I wouldn't spend the money to buy this product. For better results and without the tooth aches, I would spend the time and effort in using the daily strips for a week or two.

It was pretty easy to put on and adhered to teeth pretty well. There was a bit of a funny feeling but I got pretty used to it. I actually fell asleep after I put it on and within 50 minutes I woke up to a sharp pain of sensitivity on two areas of my teeth. I tried to bear with it for a few more minutes but the same spots actually were starting to throb with pain. I took them off immediately. There were some white patches on my teeth that were brighter but went away by the morning. I can't really say if it worked because I only had it on for about an hour. Not sure if I am willing to try it again because of the sensitivity.

I had been wanting to try Crest 3D Whitestrips 2-hour Express for so long, and was extremely anxious and excited when I was chosen for this review! I put the strips on the same day I got them, and I must say after the incredibly long 2-hour wait, I was less than thrilled with the results. I did not notice much difference in the colour of my teeth, if any at all. I was really hoping to dramatically and quickly brighten my smile, as this product claims it will do, but sadly it did not. I'm glad I did not buy this product on my own....I would have been very disappointed. :(

My free sample of crest 3D white whitestrips arrived just in time! I had recently been feeling my teeth were on the yellow side and was in need of a whitening product, and thankfully the 2-hour express delivered!
I had used past whitestrips with success but was annoyed with the routine. (using them twice a day, or for a number of days in a row) I was really excited to try a 2 hour version that only needs to be used once every 3 months!
Two hours does seem like a long time, but I decided to give myself some tv time while wearing them.
The strips were easy to use and apply, stayed on relatively well (I tried not to talk too much with them on), and didn't really notice an unpleasant taste until the last 20 minutes.
After removal I was pleasantly surprised with the results! Definitely a noticeably whiter smile, but not too "i just whitened my teeth" white! Perfect!
The only negative was about 3 hours after I whitened them I began to feel the sensitivity in my teeth. It was quite uncomfortable (I have had sensitive teeth in the past) and found it annoying while tying to fall asleep. When I awoke the pain was still there. I worried about how long it would last but thankfully later that day it went away. (lasted less than 24 hours in total)
Even with the sensitivity I was so impressed with the result and ease of the product I would definitely buy and use again!

I want to try Crest 3D White Whitestrips 2-hour Express for so long and was very happy when I was chosen.
I tried it 3 days ago. The strips were easy to put on and not hard to take off. They were easy to wear and easy to ignore. I couldn't wait to see the final result, but I was very disappointed. My teeth looks almost the same maybe just a bit whiter. But the worst part of these experience was 3 hours later, my teeth hurt so much that I couldn't eat, drink, even open my mouth (normally my teeth are not sensitive). Even now my teeth a bit sensitive. I wish I could see better result, but even my whitening toothpaste doing better job.

Though easy to use, the strips were disappointing. They promise noticeably whiter teeth, but I'm hard pressed to find a difference. I had high hopes for a brilliant, white smile but am sad to report I didn't find much (if any) difference after the 2 hour application. The strips adhered quite well, they did foam a bit but after 15 mins or so they were easy to ignore. They stayed in place which was great, they did have an advanced seal as far as I could tell in comparison to other Crest white strips, but as for their whitening factor, I was less than impressed.

I was chosen to review this product through the Product Review Club. I got the strips just in time for a wedding I was going to. I had never used any whitening strips and was a little terrified that my teeth would become extremely sensitive and/or painful.

First problem is that I have an orthodontic wire behind my bottom teeth to prevent them from moving. The Whitestrips instructions say do not use on dental braces. So I decided to try chatting online with one of their staff members to see if I could use the strips on my bottom teeth because the strips folds over and sticks to the back of your teeth. The person was totally unhelpful and kept repeating herself saying you can't use it on braces and it only whitens the front of your teeth. Anyways, I decided to use it despite the wire as the strip only folds over to halfway of your back teeth. I had no problem removing the strip from the wire, which it did come into contact with.

The next problem I encountered was which strip was for the bottom teeth and which one was for the top and which edge of the strip was to be folded over and which was to adhere to teeth. Eventually I took a chance and felt the longer strip was for the top and the shorter strip was for the bottom and the straight edge without the cutouts did not fold over.

I put on the strips and was good to go. They adhered to my teeth and didn't move for the 2 hours. But, I have a terrible gag reflex and started gagging at times throughout the 2 hour treatment because I couldn't put my teeth together because of the sensation of the strips against each other (drove me nuts!). So my mouth was slightly open for 2 hours. When I spoke people told me I was talking funny. Not only that but the product on the strips began to bubble and stayed that way for 2 hours. I would recommend using this product when you know you have 2 hours to kill in the comfort of your own home and in without speaking to anyone.

During or after the 2 hours, I did not experience any tooth pain or sensitivity. It looks like I'm one of the lucky few. That said, it may not have occurred this time around because it was my first time using a whitening product (aside from toothpaste).

I had no difficulty removing the strips after the 2 hours. I was, however, disappointed that my teeth did not appear any whiter than they normally do. I use the Crest Vivid Whitening toothpaste and find that it does the same job as the 2 hour express whitestrips and I don't have to go to the hassle of sitting there, unable to talk or close my mouth for 2 hours.

Bottom line: I would not recommend these whitestrips, especially given the price, but I would recommend the 3D Advanced Vivid Whitening toothpaste.

I was so excited that I got to try this product for free from chick advisor because I always wanted to try the crest white strips, but was not sure if they would work so I never bought them. I feel that my teeth are not as white as I would like so it was great to be able to try something.
I really liked this product because it was fairly easy to use and I did not have to wait too long before I could take them off which is nice.
I felt like this product did whiten my teeth somewhat, and I am sure that after using the rest of them throughout a year maybe I will see better results as time goes on.
I would forsure reccommend this to others because it is way cheaper than going to the dentist to get them done and they do work pretty good so it woudl save a person a fair amount of money.

So here's the thing - the strips are much longer for your teeth so you'll need to play around with it a little to ensure that the strips don't slip off your teeth. Make sure your mouth is dry - i.e. spit out your saliva because some of the peroxide will mix in with your saliva and instead of swallowing - I would spit it out. The taste also leaves a lot to be desired and may not be ideal for everyone. I had it on for about 30 mins and felt a bit of stinging, but as I have a high pain tolerance just left it on. Didn't keep it on for the full 2 hours, think I took off after 50 mins or so---just didn't have the patience for it and plus my gums were starting to get really sore and sensitive. My teeth do look whiter. I think to really see a difference your teeth needs to be a little yellow - stained from drinking too much tea, coffee or smoking. The sensitivity and the soreness did eventually disappear. The postitive points are: one treatment every 3 months, so ithe box will last you years and years, do see a difference in terms of your teeth getting whiter. The not so good points: 2 hours of having to leave on--think it's too long of a wait, messy and strips were too large and didn't adhere as well as they should have, sore gums and teeth, but this does eventually go away, and taste of the gel should you get any in your mouth is horrible.

Overall I'm not sure that I would purchase these again and am not sure if I am going to attempt a full two hour treatment. However if I had friends that really needed to whiten their teeths before an important event - i.e. wedding, prom, etc etc - I would tell them to try because I did see pretty good results of removing the stains from my teeth.
