I was lucky to be chosen to test of Crest 3D Whitestrips 2 hour express. I had high expectations after reading some other reviews prior to using the product. I have used whitening toothpaste in the past and being a daily tea drinker, my smile needed a bit of whitening. The strips were easy to put on and stayed put during the 2 hours. I had a bit of foaming but nothing that was bad. When I took the strips off I was expecting better results than what I received. I definitely didn't receive the level of whitening that is promoted. My teeth looked slightly brighter but not something that I would have been satisfied with if I paid the full price for this product. My teeth were sensitive for the following 2 days and I would get the occasional sharp shooting pain. Sensodyne toothpaste seemed to help with this.

I tried this product hoping it wouldnt cause alot of sensitivity. After roughly 20 mins, I had to take the product off. My gums were so sore and continued to be sore for about a day.

I have used whitening products before and never have had such a reaction. I think I need to try a strip that doesnt require to be worn for 2 hours, but I understand the need to wear the strip for 2 hours, so THIS product as its supposed to work that quickly.

I will attempt again but am not optimistic to have a good result. However, I am happy that I was able to try these product.

I have used other whitening products before (toothpastes, professional teeth whitening product from the dentist) and overall, I am pleased with this product.

The strips were easy to apply, but i noticed right away that they seemed like it would be difficult to keep them on for two hours. The strips felt like they were going to come off, so I just did everything in my power to keep my mouth shut. I wouldn't be able to do anything too complex (no talking) while the strips were in, for fear that they'd come off. But - who says we don't deserve two hours to ourselves?

There was no burning sensation, I was expecting something, since I have sensitive teeth sometimes, but the process was painless. My teeth were noticeably whiter, which was awesome! Two hours, whiter smile = happy!! I'm also really glad that the box comes with enough strips to maintain or "freshen up" every three months, so for a whole year. That makes this product a winner in my books!

I have never used any tooth whitening strips before, although I have tried various brands of whitening toothpaste over the years, usually with very little noticeable results. I found the Crest 3D Whitestrips 2-hour Express extremely easy to use. It's super important to make sure that your teeth are dry before you apply the strips. It definitely makes them stick on better and not slide around as much during the 2 hours that you have to leave them on. The taste of the peroxide was a little strong for me, but nothing that would induce a gag reflex! It really helps to rinse your mouth as soon as you take those strips off, and brush your teeth, but gently. I found that my teeth were a little bit sensitive for a couple of days after, but that eventually wore off. I wouldn't say that the results were super bright and white, but I did notice a slight difference, and my teeth definitely felt a lot "cleaner" and smoother after. For the little amount of time that I had to invest in using the product, I thought the result was definitely worth it.

I had always wanted to try a teeth whiting product but had never gotten around to doing so...until I received this product as part of the product review club. I must say, that I am not sure if I will try an over the counter whiting system again. Overall, I was quite disappointed with the results of the product. I have fairly good dental hygene habits and brush and floss regularly - I was simply looking for a product that would brighten and whiten my slightly tarnished teeth. I am not a smoker, but I do drink coffee, so I was holding out high hopes for this product to improve the appearance of my teeth. Although the strips were easy to apply, I found it hard to keep them on for 2 hours...they started lifting at the base of my teeth. However, I did not experience any sensitivity. After I took the strips off, I must admit I was disappointed. My teeth felt very smooth, but they did not look noticabley brighter or whiter. My husband, who was not with me while I applied the strips, did NOT notice a change in the slightest...even after I explained what I had done. I would probably not recommend this product, due to the lack of results, and I most likely will not purchase it in the future.

THE REAL SCOOP

All the whitening power of Crest Whitestrips, in a convenient 2 hour application that would last for months? Well, this I had to see. I have fairly white teeth, don't smoke and don't drink coffee much but everyone can use a bit of brightening for their smile, right? I've used white strips (7 day application) before and the premise for these strips is promising.

The strips do actually stick on better than their weeklong peers. The ease of application is about the same, and I found the sensations/sensitivity to be about the same. My teeth were sensitive to cold for 1.5 days after application but they are better now. Interestingly enough, my gums also lightened up during that period but they are back to a normal colour now.

In terms of efficacy, I don't see a big difference between the results of this product and the regular strips but the advantage of course is the time savings. 2 hours is a long time to be sitting with something on your teeth, but it beats having to do it everyday for 7 days! I had fairly white teeth to begin with, so I cannot attest to how it will work on someone with significant staining. The fact that it only needs to be "topped up" every 3 months or so is a big plus. This would be nice before a big event to brighten those pearly whites.

BOTTOM LINE

I had hoped for more dramatic results (like those super white teeth you see on celebs with veneers) but for the amount of time invested, it is a decent product. I may consider purchasing again if it goes on sale but it is not a "holy grail" product for me.

When I first put on the strips, I found them excellent as they really stick to your teeth. Even though I have "large" teeth, there is enough strip to cover all of them. After an hour, I found some tooth discomfort. It was like a deep "ache" inside my teeth. I didn't find any gum discomfort though. After the first hour, I was excited to see if I could see any change in the colour of my teeth, but I waited the full two hours. The foam and paste did not leave a bad taste in my mouth. I only saw one "whitespot" that occured on one of my teeth, but it disappeared within the hour. A few hours after the cleaning, that dull ache occured again in a few teeth and it was noticable. I chalked this up to me being 40 years old and some tooth sensitivity.

I didn't notice a difference in the colour of my teeth though but will use it again in another 3 months to see if there is any change.

I have tried other whitening strips before and these ones are the most effective ones I tested so far.
The whitening effect was definitely visible after using them. The only downside is that I felt some sensitivity for about 1 day after using them, but now everything is back to normal, just whiter!

Firstly, I had a hard time finding enough time to do this. I opted to do it while I worked on the computer in the evening.
I then had a hard time figuring which was the bottom and which was the top strip as neither one really fit the top or bottom quite right. After I decided to use the small on top and the long on the bottom, I applied them as stated in the instructions.
I started to work while I was waiting for my time only to find that my mouth watered continuously and the strips seemed to keep unfolding.I found this quite annoying and had to stop working in order to pay attention to the strips and my overly watered mouth.
After 2 hours of this aggravation, I removed the strips only to find little to no difference and then had to deal with 3 days of very sensitive teeth..
For the amount of time and annoying effects it causes, these strips are definitely not worth my time or money. I will not purchase these.

I was really looking forward to trying out the 2-hour express 3D Whitestrips thinking that they would be more effective than the regular strips. I was a little disappointed noting little difference between the 2 Hour Express and the regular Crest Whitestrips. 2 hours is just too long for me and i found my teeth to be very sensitive for several days. Will not be purchasing.
