Well, they work
First and foremost, these things deliver on their promise to make your teeth "noticeably whiter" in two weeks. I'm not going to complain about that.
However, I have noticed the following things:

Crest White Strips Do Work - A Dentist Reviews this Product, August 3, 2005
This review is from: Crest Whitestrips Dental Whitening System, 56 Strips (Health and Beauty)
I am a dentist who recommends Crest White Strips because they do work to whiten teeth. Follow the directions in the box, and here are some further tips:
1. (Optional step) I recommend you first brush your teeth with water (don't use toothpaste) to remove the layer of plaque. Your enamel has pores and the pores need to be open for the chemical to penetrate. If you use a fluoridated toothpaste, the flouride may block the enamel pores. (Crest's instructions indicate you do not need to brush. I talked to a Crest representative on this point, and she indicated that the hydrogen peroxide will penetrate plaque, therefore this step is optional. The instructions indicate no brushing because they do not want fluoridated toothpaste on the teeth before whitening).
2. Use the strips twice per day for maximum efectiveness. The inner part of the strip has a chemical called carbamide peroxide (a 6% form of hydrogen peroxide; in-office dental whitening uses a 15-30% version of the same chemical) that causes the stains inside your teeth to be oxidized and turn white. Applying the strips has a small learning curve as you will probably bend or fold a couple of them before you get the technique down.
2. Leave the strips on for 30 minutes at a time. After thirty minutes your saliva has probably diluted the peroxide to the extent that it is no longer effective. You can reapply a new strip immediately if you chose, for the treatment requires one hour of treatment time per day to work. It does not matter if you do this in one continuous 60-minute period or two 30-minute periods. Do this for two weeks and your teeth should get whiter.
Disadvantages
1. The chemical may "burn" your gums. If you notice a burning sensation when you use the product, it is the peroxide oxidizing (or burning) your gums. Depending on how severe the burning is, it may cause you to stop the treatment. It is OK to stop the treatment for a day or two to let the gums heal. Once they feel normal again, resume treatment with the White Strips.
2. Your teeth may become senstiive during the two-week treatment time. Try to push yourself through the sensitivity if it is mild, but if it bothersome to cold water or air, take a day or two off to let the teeth settle down and then pick up where you left off.
3. The strips only cover your front teeth, so only your front teeth will bleach. You may notice the distinct difference between the back (unbleached) teeth and the front (bleached) teeth. Since most people notice the front 6 teeth anyway, this is not a concern. However, if you have a wide toothy smile, you may want to have a dentist make you a tray that will hold the chemical on the back teeth to whiten them too.
3. The bleaching effect works best on yellow stains. If your stains are due to tetracycline (brownish grey stains in a band on your teeth, your best bet is to have a dentist whiten your teeth as the dentist will use a tray to hold a more concentrated form of the chemical on your teeth for a longer period of time.
Crest White Strips work for the vast majority of people. Over time, you will get a result that should be whiter than when you started. Crest White Strips are a good place to start with bleaching, and if you are not satisfied with the results, you can then see your dentist for a more concentrated form of bleaching or other cosmetic options.

They work!, August 2, 2006
This review is from: Crest Whitestrips Dental Whitening System, 56 Strips (Health and Beauty)
First, this product really *does* whiten teeth--it's not a gimmick as some people think. (It uses a peroxide, which is probably how your dentist would do it, although this is a less concentrated form and takes two weeks.) Of course, it only whitens natural teeth, not dental work, but for most people, they should work.
Now, on to the product itself. Some people have complained about them being difficult to apply, but after the first couple strips I didn't have any problems, and even the first time I applied it I didn't fold a strip or mess up anything major. Keep in mind that some tooth sensitivity is normal; personally, mine was only mild at worst and really only noticeable right after I applied a strip, but I know some people who aren't as lucky. If this is you, using a toothpaste for sensitive teeth may help. Also keep in mind that eating, drinking, and probably talking (unless you have better luck than I) are pretty much out of the question while you're wearing these, but I simply did one application on my drive home from work and another later in the night. My only concern was that the strips, especially the top ones, are a bit short and only cover your front eight or so teeth, but for most people that shouldn't be a problem.
A year after my first use (teeth still looking good), I am currently using a generic brand--Equate, available from Wal-Mart for about $15, about $5 less than these--and have to say that I like Crest Whitestrips better because the strips are more flexible and easier to apply, and they stay in place better. The Equate ones have a bit harder plastic and tend to slide off my teeth if I open my mouth. Hardly worth it to save $5.
It is also worth noting there are two other versions of Whitestrips: Premium and Premium Plus. Both contain a more concentrated peroxide that works in less time (7 and 10 days, respectively [the 10-day version is the same as the 7-day version but includes three extra days of strips for extra whitening], as opposed to the 14 of this Classic version) but are more expensive and--based on their reviews--seem to cause more problems with sensitivity and such. Therefore, unless you're in a hurry, I think you'd be fine with these.
In summary, I am happy with this product and think that most people would be, too. Not bad for the price (certainly cheaper than a professional whitening), and they really do whiten!

Great product, June 29, 2006
This review is from: Crest Whitestrips Dental Whitening System, 56 Strips (Health and Beauty)
I love this product. It is true what other say about the sensitivity. I would recommend using sensitivity toothpaste while you are using the strips, it helped for me. It made my teeth noticeably whiter. I would suggest you take a picture of yourself smiling before and after. I noticed the whiteness of my teeth when I saw a picture taken recently and I couldn't believe how nice they looked. I just had to dig up an old picture to compare and it was a big difference. After I have noticed this in the new picture, I love smiling for pictures now and showing my teeth. I was alway self conscious about it before. That alone makes it worth the price.
I was very satisfied with my results. Make sure to read all the instructions before using.
It just became a part of my bedtime routine, not a bother at all. I just put one on while I was watching my evening TV programs and just kept an eye on the clock.
Also, I recommend that after you have finished your pack that you use the Crest whitening toothpaste. It really helps to keep your teeth staying white.
Great product and it was recommended to me by my dentist.

A Dentist Reviews This Product, July 21, 2007
I am a dentist who recommends Crest-brand White Strips to my patients becasue they do work to whiten teeth. However, they have to be used correctly and I recommend that you follow the directions as specified inside the box.
1. Use the strips as directed on the box. The instructions will tell you to bleach twice a day for 30-minutes a time. The inner part of the strip has a chemical called hydrogen peroxide; (in-office, or dentist-assisted dental whitening uses a 15-35% version of the same chemical) that causes the stains inside your teeth to be oxidized and turn white. Applying the strips has a small learning curve as you will probably bend or fold a couple of them before you get the technique down.
2. Leave the strips on for the time recommended in the instructions and do not overbleach your teeth, as this leads to sensitivity.
Disadvantages
1. Hydrogen Peroxide can "burn" your gums. If you notice a burning sensation when you use the product, it is the chemical oxidizing (or burning) your gums (it will turn them white with a minor chemical burn). Depending on how severe the burning is, it may cause you to want to stop the treatment. It is OK to stop the treatment for a day or two to let the gums heal. Once they are healed, resume treatment with the White Strips. Try to not get the strip on your gums.
2. Your teeth may become senstiive during the week treatment time. Try to tolerate the sensitivity if it is mild, but if more severe, take a day or two off to let the teeth settle down and then pick up where you left off. You may notice much more sensitivity to cold water, ice cream, etc. The peroxide causes a reversible inflamation of the inner pulp, or nerve center of the tooth and makes the teeth very sensitive to biting or cold drinks or foods. If your teeth become too sensitive, back off on the strips until the sensitivity is gone before resuming bleaching.
3. The strips only cover your front teeth, so only your front teeth will bleach. You may notice the distinct difference between the back (unbleached) teeth and the front (bleached) teeth. Since most people notice the front 6 teeth anyway, this is not a big deal. However, if you have a wide toothy smile, you may want to have a dentist make you a tray that will hold the chemical on the back teeth to whiten them too.
4. The bleaching effect works best on yellow stains. If your stains are due to tetracycline (brownish grey stains in a band on your teeth, your best bet is to begin bleaching with yoru dentist and then use the strips to continue the bleaching process.
Now comes the confusing part: Crest White Strips come in 4 different packages, each a bit different than the others. The main difference is in the strength of the hydrogen peroxide, and the price. The higher the dose of hydrogen peroxide, the most costly the product package. Here are the 4 packages: 1. Crest White Strips Classic (6% hydrogen peroxide, 14-day treatment). 2. Crest White Strips Premium (10% hydrogen peroxide, 7-day treatment). 3. Crest White Strips Premium Plus (10% hydrogen peroxide, and has 12 additional strips). 4. Crest White Strips Renewal (9.5% hydrogen peroxide). The cheapest method (at around 25 dollars, is the Crest Classic Whitestrips, but it takes 2 weeks to complete the treatment). Premium and Premium Pro are both 10% peroxide formulations, work in 7-10 days, and the "Premuim-Plus" gives you 12 additional strips. I am not sure why Crest recently came out with "Renewal", as it is a 9.5% hydrogen peroxide formulation which is not significantly different from the 10% concentration. Leave it to the manufacturer to confuse the consumer!
Crest White Strips work for the vast majority of people. Younger people with yellow stains seem to respond better than older people or those with gray stains.
If you are not satisfied with the results and still want whiter teeth, you can then see your dentist for a more concentrated form of bleaching. This is much more expensive, but the concentration of hydrogen peroxide is much higher and this works better on stubbornly-stained teeth.

*~*~*SPARKLING, SHINY TEETH!!!*~*~*, May 26, 2006
This review is from: Crest Whitestrips Dental Whitening System, 56 Strips (Health and Beauty)
I just finished my two weeks using Crest Whitestrips. I was a little skeptical about whether it would work, but after reading the reviews I tried it. My teeth weren't really bad, but they had a bit a yellow-ish coloring and weren't the brightest. I swear I noticed a difference after 24 hours! After the first week, my teeth weren't only white, but they were also shinier. I'm so glad a spent my money & time on this whitening system!!

An Inexpensive Way to Whiter Teeth, April 29, 2006
This review is from: Crest Whitestrips Dental Whitening System, 56 Strips (Health and Beauty)
Crest Whitestrips are one of the most popular among the store brand tooth whitening products. They were introduced to the public in 2001 and they have been satisfying customers ever since. They work by concentrating special whitening ingredients like peroxide directly against the teeth where they can penetrate the surface for a full thirty minutes. Repeated usage for fourteen days should result in significantly whiter teeth.
Crest Whitestrips claim that these strips can be worn and used any time and that, once in place, you can go on with your normal daily routine for 30 minutes while the strips have the opportunity to work. It is true that you can do what you want, but there are certain activities that are not easy to do with one of these strips in place. I'm one of those people who has a tendency to want to move my tongue around when a have some type of dental object against my teeth and more than once, I have accidentally pushed the strips out of place. The gel helps to hold them in place but they can still be moved with little effort. Also, if you start talking with a Whitestrip in place there is a chance that some of your words will come out a little funny- like someone who has had a little too much to drink. I have found that, for best results, I try to do nothing at all when wearing Crest Whitestrips. The best thing to do is read a book. The time goes by quickly and it makes it easy to forget the strips are in place.
Waiting for fourteen days is frustrating and it is possible that you may need a second treatment after the first, depending on how well you stick to your 30 minute per day schedule and how well the Whitestrips stayed in place. But the results should make you happy. At first I avoided Crest Whitestips because of the price and because of the product itself. Spreading liquid gel on the teeth seemed much simpler than having to wear an object against one's teeth. I didn't like the idea of hassling with strips so I avoided buying Crest Whitestrips and tried the liquid variety in its various forms first. I finally gave in and purchased Crest Whitestrips because I got tired of waiting for satisfactory results. And I did get good results with these strips. I followed the advice on the package and used the upper strips twice per day first, then the lower strips twice per day for the next seven days. This is a good idea because you can compare the shade of the top teeth with the bottom, right after the upper treatment is completed. I could see a significant difference as all those years of soda pop, coffee, tea, and other staining drinks were suddenly washed away.
Crest Whitestrips use the same chemicals that dentist's use to clean and whiten teeth, so they are safe if used as directed. They are designed to keep teeth white for six months after each fourteen day period of usage. They also come with a money back guarantee. In order to get the guarantee. If you are not satisfied with the results, you can get a full refund of the purchase price provided you have followed the correct procedure for a refund.
Crest Whitestrips work well, but like other over the counter whitening products, they only work on natural tooth enamel. They will not whiten dentures, caps, crowns, or other artificial dental material. If you have teeth with artificial surfaces that are badly stained, you will need to seek the help of a dentist or other professional to get rid of the problem.
Crest Whitestrips are a little more expensive than the liquid whitening formulas but Crest Whitestrips are also more effective. I am satisfied with Crest Whitestrips and I recommend buying a box for effective treatment of discolored teeth. They are not as thorough as the treatment provided by a dentist but all things considered, these strips are a good buy. They eliminate stains and return your teeth to a more youthful appearance in only two weeks if used as directed.

Fantastic!, August 30, 2005
This review is from: Crest Whitestrips Dental Whitening System, 56 Strips (Health and Beauty)
The Crest White Strips have worked really well for me and I have nothing but good to say about them. I understand that other people have complained that they are tricky to put on and that they were painful, but I experienced neither. I found them easy to apply, I am totally able to speak while they are on (with a slight lisp!), and for me they were not painful at all. My teeth are noticeably whiter and I am very happy with the whole experience. My concern was if they were good for my teeth (I didnt want to accidentally do irreperable damage to my enamel) but a conversation with my dentist solved that completely.
I will definitely use them again if required and wouldn't hesitate to recommend them to others.

Well, they work, January 11, 2005
This review is from: Crest Whitestrips Dental Whitening System, 56 Strips (Health and Beauty)
First and foremost, these things deliver on their promise to make your teeth "noticeably whiter" in two weeks. I'm not going to complain about that.
However, I have noticed the following things:
-These things are insanely hard to get into your mouth the first few times. It's a shame there's no "spare" strips included, because you're likely to waste a couple. The lower strips especially are prone to getting crumpled up and ruined while trying to stick the damn thing to your teeth.
-The gel tastes terrible. I recommend brushing your teeth shortly after you remove them.
-You can't really talk, drink, eat or do anything with your mouth while they're on your teeth- even swallowing is difficult at first.
-The packaging does not stress that you need to use them TWICE A DAY. I made the mistake of using them only once a day until I luckily saw the note on the package.
But, like I said, my teeth look quite a bit better, although this isn't a substitute for brushing.

Try This Tip for Best Results, June 27, 2008
This review is from: Crest Whitestrips Dental Whitening System, 56 Strips (Health and Beauty)
I've read several comments by people who said they had trouble keeping the strips in place, I came up with a suggestion that should help anyone who happens to have that problem.
Before placing the whitestrips in place, gently pad a square of toilet paper or tissue to the front and back of your teeth, try to get those teeth as dry as possible. Maintain a big smile so that your teeth are showing, you want to make sure that your lips don't touch them yet. Place the whitestrips in place, one at a time, try allowing for an equal amount of strip for the front AND back of the tooth. Push it firmly in place, and use your fingernail to gently push the front of the strip into the spaces between each tooth (to ensure that the gel makes its between each tooth, and not just the front surface). I have found that by drying your teeth well, the strips won't move the slightest bit, compared to when I first tried them and they slid around a little.
The Whitestrips work well, I noticed a big difference after only five days. Although my teeth weren't that stained before, I was always a little self-conscious about smiling with my mouth open when talking to people. But now, I do it with no hesitation, and have a lot more ladies complimenting me on my smile. It's great what these little whitestrips can do for your self esteem, I'd recommend them to anyone in a heartbeat.

Great product, great results but.., June 10, 2005
This review is from: Crest Whitestrips Dental Whitening System, 56 Strips (Health and Beauty)
I concur with the rest of the reviews. They do make your teeth whiter (for me i noticed a difference after the first application). Also people stopped me and complemented me on my teeth.
However the things are very hard to put on your teeth. The top ones are easier, but the lower ones are very tiny and often slip off.
It also takes one or two applications for your mouth to get used to them. So make sure have a towel on standy if you intend to use them (they make you salivate)
