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.

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. :(

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.

Thank you Chick Advisor for giving me the opportunity to try out the new Crest CD Whitestrips 2-Hour Express.
My overall experience with this product is different from the ones that I have tried in the past. First off, the length of time that I had to keep the strips on for; that didn’t bother me because I kept myself occupied for that 2 hours anyway. I like how I didn’t have to struggle with “slipping strips” because this one stayed put from the time I put them on. I feel as if the top strip should be a bit longer though.

The strips were not hard to take off, but it’s definitely an improvement from the last whitening strips that I have tried previously. The only issue I have right now is that my teeth are hurting. I don’t have sensitive teeth, but right now I am feeling slightly uncomfortable. Hopefully this will wear off within a day.

I haven’t noticed too much of a difference with my teeth, but I did take a “before” picture, so I really should take an “after” picture and compare the two. Would I try these again? Sure, we did get a years’ worth of whitening strips, so why not? I just need to be watchful of the sore teeth…


Thanks again.

Thank you to Chick Advisor for letting me review this product.
The box comes with 4 sets of strips. One strip to be used every 3 months and the box is therefore good for whitening your teeth for a year.
The strips were fairly easy to apply with easy to follow instructions that came with the packaging. The strips stuck on well. They tasted a bit weird though. They were easy to take off as well. The results were a little dissappointing though as I did not notice much of a difference in the colour of my teeth. They were very slightly lighter although I was expecting a much more noticeable result. I do not smoke or a heavy caffeine consumer so my teeth are not that stained to begin with. So I doubt this product would work if at all for someone with heavily stained teeth.
I have sensitive teeth to begin with and the next day of using these strips my teeth are extra sensitive. This was mentioned as a side effect in the package instructions though so hopefully it will go away in a couple of days.
I should mention though that my teeth do feel cleaner.
I guess for now will have to depend on professional whitening at the dentist's. I give this product a thumbs down. Not worth it.

My initial thoughts on this product. While reading through the little booklet that comes in the box I didn't notice very complex steps. They were pretty vague actually. They have three steps to remove from packaging, place on teeth, and remove after 2 hours. I figured it would be easy enough I just needed to find 2 hours that I wouldn't be hungry or thirsty. That is actually pretty hard for me! You also can't brush your teeth before doing the treatment so doing later at night was out of the question too.
Upon opening the strips and trying to apply them I noticed they were really long for my mouth. I don't know if anyone else had problems with them, but for me I had problems getting the top ones to stay put. They kept sliding because I couldn't wrap the ends under because they were so long they went back to my molars and didn't adhere 100% at the back which made them shift down. Once they were applied I noticed that I had a lot of saliva and I really wasn't sure if I could swallow it or since these strips are peroxide if I had to spit it out. I opted to spit it out and that was when I started having slippage problems with the top strips. I really wish they had more instructions in the booklet. I ended up trying to search the internet for the answer. The taste also leaves a lot to be desired and may not be ideal for anyone with a delicate gag reflex. I got about 20 minutes into treatment and my teeth and gums were hurting so bad I opted to remove the strips. My gums were actually bleeding as soon as I removed the strips. I can't fairly judge how well they whiten since I didn't stick out the full two hours, but for me personally the pain is not worth any amount of teeth whitening.

Pros

One treatment every 3 months
One box is a years worth of treatments
Easy to follow instructions
Large strips that cover well

Cons

Kind of messy if you have to keep repositioning them like I did
Strips were too large for my smaller mouth so they didn't adhere as well as they should have
Bleeding gums after 20min
Very sore gums and teeth after only 20min
Taste is horrible

Overall I would never purchase these again and am not sure if I am going to attempt a full two hour treatment since my gums are still throbbing from the short time they were on my teeth tonight. I think I would rather use whitening toothpaste and mouthwash since I don't have badly stained teeth to begin with.

I whitened my teeth today with these Crest whitestrips and I was quite disappointed. I really didn't notice much of a difference at all :(
My teeth weren't horribly stained or anything, but they could have used a little brightening. The first problem for me was the lack of instructions, I mean it's not like you need to be a genius to understand what to do but it really would have been helpful to have more information.
I found the bottom strip to be a little small and the top one a bit too big, I had trouble getting in my mouth. I noticed a bit of a taste, but nothing unbearable. It did feel weird at first and i wondered how I would last 2 hours, but I got used to them after awhile. I didn't experience any discomfort while I had them in nor when I took them off.
I found taking them off was a bit difficult and the strips were very sticky, even so my teeth were not. I didn't feel any residue or stickiness, my teeth felt super clean but weren't very noticeably whiter. My top teeth maybe, but I had difficulty with my bottom teeth, they aren't super straight so I had to play around with the strip to get it on right. I was worried about tooth sensitivity, but I had none.
I'm going to get my boyfriend to try them out and update if he has results. I'm happy I got these through the review club because I would have been angry had \i paid that much for nothing.
