Crest 3D White Supreme FlexFit Whitestrips, 42 Strips (2 pack)

These are really easy to use (peel and stick). Even after the first use I noticed a slight difference. Continuing to use my teeth are a lot nicer than before. I've used dissolving ones before and I really didn't like them. These are much nicer to use. I have wires on the back of my front teeth and am still able to use these.

I've always wanted to try these but have been worried as I have very sensitive teeth. My teeth are pretty stained from years of drinking coffee and tea. Within 4 applications I could see a very big difference my teeth were so much whiter and brighter. Much to my surprise I did not experience any sensitivity while using this product or after. I highly recommend this product to everyone for quick results that last!

I tried crest white strips when they were new one the market many years ago. They were messy, made my teeth extremely sensitive and overall i didnt see much of a difference. I was excited to give them another go as professional whitening has become so expensive. I am SO happy to say no change to the sensitivity of my teeth. These are much easier and less messy feeling in your mouth. These are actually up to par with a professional treatment. It might take longer but it is well worth it.

The strips when applied will not stay in original spot! I've ruined 5/6 strips already only one week into the product. Not very happy !! Results are showing a bit but process is slow.

These strips work great, I instantly noticed a difference within the first week, I am a heavy coffee drinker and noticed my teeth starting to whiten instantly. I did find the bottom a little hard to get on at first but after a couple times, i made a routine of it. I will say that your teeth become very sensitive to Cold drinks. I would definitely purchase this product again.

After two weeks, I noticed a significant improvement. The strips were really easy to use and didn't move or side around. The instructions say you can stretch them, but I didn't find them to stretch much, however, I also found I didn't need to. They had a bit of a taste but not a bad one. I started to notice my teeth were pretty sensitive after the first week, and became increasingly so. This product does a great job at whitening your teeth, much better than I thought it would. I would useit again for a special occasion where I was going to be smiling in a lot of pictures. However the increased sensitivity wouldn't be worth it to me for just regular whitening.

I quite like these white strips, they stay in place and whiten very nicely. I don't know if it's just me but I find I can notice a difference after just one application, my friends and family noticed after a week. The only downfall is they do make my teeth a touch sensitive, however it is not very bad and a small price to pay in music opinions for a brilliant smile. All in all I love this product and will.definitely continue to use and recommend it.

So I tried the Crest 3D White Supreme FlexFit Whitestrips, and I personally like them. After only a few days of use, I could see my teeth whitening. The strips are very easy to use - you simply line the edge of the strip up with your gum line, stretch, press and fold the excess strip over to the backside of your teeth. For me, it really was that simple. I did not have any trouble with the strips sliding around or shifting once applied. I did make sure that my teeth were a bit dry before I would adhere the strips to my teeth. I am not sure if this was indeed helpful in making the strip stick, but I feel like it was. I think perhaps the top strip was easier to apply and that it gripped my teeth better than the bottom strip did because I could really feel the strip stretch and grip snugly onto my top teeth. The bottom strip, not quite so much. I know in other reviews, some have found these strips to be goopy when you are putting them on/ wearing them, but I didn't find that at all. The only one thing I did find after using these strips for a while is that they made the bottom edge of my two front teeth sensitive, but it seems to have disappeared now since I finished using them. After using these crest whitening strips I do think my teeth look a lot nicer and whiter than they were prior to use. They maybe not be perfectly white - perhaps not to the extent that a professional whitening treatment would provide, but I think they really did a great and very satisfactory job for the price, time and effort required to use them. I would buy them again for sure. **Note: The photo shows my teeth after a mere week of use. Pretty good for only one week!

These start sliding around instantly. So after 1-2 min of trying to put them on they basically end up somewhere else in ur mouth. Honestly just buy a different type of crest whitestrip. I love the others... Supreme is terrible.

Didn't make my teeth whiter, brushed my teeth 3 times per day..stopped drinking coffee as well.
