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 recently got to try these and because there was more then one set in the box, I also got my friend to try it as well. The results for me were great! It wasn't hugely noticeable right away but after a little while I was starting to notice me peeking at mirrors and smiling at the result. My friend, however, did not have such a great reaction. Although it whitened her teeth very noticeably (she's a smoker and it really helped lighten that yellowish stain from around her gum line) she complained for many hours after that her teeth were hurting a fair bit. Neither of us have sensitive teeth so we found it a bit odd. She ended up having to buy a tube of Sensodyne to try and relieve the ache. The last I talked to her that day was about 10hours after removing the strips and they were still bad then. She was thrilled with the result but not so happy with the pain. I myself didn't have any trouble and can't wait to try them again but I don't think I'd buy them at the listed price. It's a bit out of my price range at least.

I got a chance to try these strips through the Product Review Club, and I'm really glad I did. THey worked really well for me. I didn't have a TON of discolouration before use, so I can't speak to how well they would work with severely discoloured teeth, but for the average 'love coffee and red wine' (and have done for at least a decade) kind of woman, I can say that these seem to work fabulously (at least they did for me). After using the strips, I noticed a clear difference right away (I'd say about 2 shades whiter than before), and so did others who know me well. I had one friend ask right away what I had used and who went out and purchased it based on my results. I will and already have recommended the strips to friends, and would use them again myself. I also asked my dentist for thoughts on safety and effectiveness, and he said he's heard good things from other clients and that they are completely safe.

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.

Used the strips and I am very very satisfied with the result!
Great side kick for a beautiful smile for sure.. It is fast and effective.
Got great compliments and definitely recommend it. Do not brush your teeth right before you use it.. And make sure your teeth are dry (no drinking before either) so it stays in place and make it easier.. After the first application it was ok.. But after 2 applications voila! The results is pretty obvious!

WOW! I have tried many different whitening products to try and rid my teeth of the stains from smoking and drinking coffee, all to no avail but the Crest 3D whitening strips are amazing. In just 2 hours I saw a marked improvement in the colour of my teeth. I Love how easy they are to use... they have notches on them to show you which side of the strip goes in the front and back which is extremely helpful for someone like me. I love that I can still drink water while using these so I don't have to sit there dying of thirst just to get whiter teeth. The best thing about these strips though has to be the fact that you only have to use them once every three months! I know the first time I saw the price of them I kept walking saying no way would I ever spend that but in one box you are getting a years supply of whitening products!!! That is amazing value in my book! This is definitely a product I will keep on buying!

I recently tried Crest 3D White Whitestrips 2-hour Express. I've only whitened my teeth once before, and I must say, my experience was much better this time. I loved that the strips stayed on my teeth so well. Not once did they start shifting or falling off my teeth. The taste wasn't the greatest, but it wasn't very overpowering either. After using the strips, I noticed a slight improvement, but it's not anything anyone else would notice. You can only use these strips once every 3 months, so I suspect that after a couple of uses I will notice much more of a difference.

The only thing I did not like was having the keep the strips on for 2 hours, but this is just a small inconvenience. All in all, I liked this product, and will continue to use it to improve my teeth. I will also happily and confidently recommend this product to my friends and family.

I was glad to try Crest 3D Whitestrips because I had seen the ad on TV and was wondering if it works. I think the box is way too big for what is inside. It is a waste of cardboard. The application was easy and I like that it takes only two hours instead of 1 or 2 weeks as with the other whitening strips I used in the past. However, you can't expect miracle in two hours. It does the job, but my teeth aren't dramatically whiter. Finally, I think it the price is a bit high, but I would have to use the product every three or four months to see if it is worth paying 55$ for it.

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 am so glad Chick Advisor gave me the opportunity to test the Crest 3D 2 Hour Express Whitestrips because I wanted to try the product ever since I saw the tv commercial. My teeth are already decently white but they could be whiter and this product did a decent job but nothing dramatic.
The product gets 5 stars from me for usability. It is easy to use, put on and keep on. I have tried other whitening strips in the past but they would move around on my teeth and were messy. The Crest 3D whitestrips stick to your teeth really well.
After i applied the strips, I forgot I had them on because I have fairly sensitive teeth and they did not bother my teeth at all. I was able to go about my daily routine for 2 hours.
I think this product would provide more noticeable results for people who have stains on their teeth from smoking, drinking coffee etc.
