First off, I had never used any kind of whitening except for toothpaste... which didn't work much if at all.
I have a unique issue, I have two false teeth that are bonded next to my front teeth on the bottom row. Teeth like those don't whiten with nay kind of purchasable methods, and only whiten from a dentist-procedure.

My teeth were fairly yellow, almost to the point that it was kind of embarassing. You also could tell the colour difference between my false teeth and my real ones. When I saw this product review become available I jumpped on it.. and got it! :)

They were difficult to put on.. at least for me. But I had no experience whatsoever in wearing whitestrips. My teeth were sensitive afterwards, but I normally have sensitive teeth, so after a couple of brushings, I was fine.

As for whitening, I definitely noticed a difference. My teeth now aren't as yellow (although could probably use another session or two to get the nice white shade), but now they're about the same colour as my false teeth, which boosts my confidence a little and I dont mind smiling anymore :)

The result wasn't exactly as much as I was expecting, though, and for those that are, you might want to look at other options before purchasing this one.

I would recommend these white strips to anyone who has fairly white teeth, but want them to be a bit brighter. My teeth are fairly white and but I had some discoloration on one of my front teeth. After using the strips, my teeth were a little brighter and the discoloration was reduced. The difference was less noticeable on me than what the before and after picture displayed shows.

The strips were easy to apply and non irritating to wear for the two hours. I had some tooth sensitivity that lasted for 2 days after using the strips. The box contents should last you for the whole year, so the value for the money is great.

I've tried white strips in the past but have found either they didn't stay in place or had to be used often to get results. This product was much easier to use. The strips were very easy to apply and I could see a significant difference after using them just once. The price is very reasonable for the quick results - I would definitely buy these in the future!

Let me start by saying that I have never had success with tooth whitening strips. In the past, I tried one, and it burned my gums so much that I had to remove it within the first few minutes.

Now, when the Crest 3d White strips were up for review, I did some research, and I see that it is supposed to be pain free. That was 100% true. I had zero gum pains while wearing them.

Unfortunately, the positives seem to end there.

I wore them for the 2 hours. They were easy to put on, however, I kept on having the sensation that they slipped off, so I had to run to the mirror several times. I saw the strips 'fizzing' and creating a paste that went over my teeth.

I had high hopes.

2 hours later, I take the strips off, and was so disappointed to see little to no improvement. My teeth looked the same. I even ask my husband if he noticed anything, and unfortunately, it was "no".

I come in with high hopes, and was left with my reoccurring sentiment that at home whitening strips just don't work.

I was super excited to try these white strips as i had never whitened my teether before. The strips were easy to apply and stayed put very well. They felt really aweful on though and i was greatful i only had to wear them for 2 hours. Once i took them off, i was ver disappionted as i didnt see any change in the colour of my teeth. The next day however, i did feel that my teeth looked whiter. I feel that these whitestrip are way too expense for the minamal degree of whitening they offer. I am very glad i didnt purchase them.

The first thing I want to mention is that the photo comparison I added is a little exaggerated - you can notice that even my skin tone is brighter in the "after" picture. Buuut... I never claimed to be a professional photographer! Now on to my review...

When I opened my Crest 3D 2-Hour Express Whitestrips, I was immediately disappointed in the packaging. The four small, flat foil packages and instructions could easily be sold in a small cellophane bag, or at the very least, a box about an eighth of the size of the one in which they came. As an eco-friendly person, I am very irritated with Crest and plan to write the company.

Application of the Whitestrips was quick and easy. I don't think this is mentioned in the intructions, but I dried my teeth before I stuck the strips to them, and I'm not sure if it made a difference but the strips stayed in place really well, and for the entire 2 hours.
During the treatment time, I noticed some slight discomfort, but nothing that stopped me from using them. No sharp pains or anything like that. I was worried about saliva accumulating in my mouth, because that's been a problem for me while I've used other whitening products - I worry about swallowing any chemicals so I find myself spitting a lot during the treatment. With these strips, the gel didn't seem to seep out as much so I felt okay about swallowing as usual. 2 hours seemed like a long time, but I just put on a movie and, for the most part, forgot I was even wearing the strips. I was pretty happy when my timer rang though! Removal was pretty easy, but they left some gunk on my teeth when I peeled them off. I had to brush after the treatment.
With regards to the effectiveness of the product, I do think they made my teeth slightly whiter (maybe it's just wishful thinking or the power of suggestion). But I don't think they're miraculous by any means. I did notice some bright white spots on my teeth immediately after I removed the strips, which was mentioned in the instructions. The pamphlet says they fade within a few hours, so I'm hoping they're gone by the morning. I get compliments on my smile from time to time so I guess it will be a good test to see if anyone comments that my teeth are especially white.
I chose to say I wouldn't recommend this product because I don't think it produces results that are worth $55. Not in my case, anyways!

Lastly, thanks so much to ChickAdvisor for providing this product for me to try!

I received the 3D Crest Whitestrips 2 hour express to try and was disappointed with them. I felt that the instructions were lacking in detail, and had to search online as to how to use the strips (I had never used any before). I didn't like the fact that I had to wear the strips for 2 hours, as I had to keep spitting the peroxide gel out of my mouth. The strips did seem to stay in place, but I felt like a bit of saliva was getting under the strips. The results: my teeth did not seem any whiter than they were prior to using the white strips. I had to brush my teeth (with only water) afterward to remove the gel from my teeth. My teeth really hurt after using the whitestrips, and it wasn't until the next morning (wearing sensitive toothpaste in my night guard) that they felt ok again. It has been about a week since I have used the Crest 3D Whitestrips 2 hour express, and I think my teeth are a bit whiter, but I would still not use them again because of how much pain I was in immediately after using them.

I was excited to try this product but overall I was dissapointed and I would not buy this product. I did not like the way that this product went on my teeth. I felt like it was not big enough to cover my teeth properly (maybe I just have big teeth lol). I also did not find that my teeth looked any whiter.

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.

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!
