 Yes, it works! February 14, 2008

I've seen mixed reviews of tooth whitening systems, but the price of this item made it easy for me to try (some systems are $100).
The first time was the hardest as I found myself drooling and had a hard time keeping the strips in for 30 minutes.
So, I started inserting the strips separately-- the upper strip for 30 min. then the lower strip for 30 min. The drooling improved considerably, and after a couple of days I was able to do both strips at once.
My teeth were noticeably whiter after 3 days, just as advertised, and I'm very very pleased with the results.

I was a bit sceptical at first, but I really noticed a huge difference in colour in only 3 days. I stopped using the product after 5 days because I liked the results. However the taste is pretty nasty and there was a mild gum-irritation.

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 exactly as specified inside the box.
1. First brush your teeth with a wet toothbrush to remove the layer of plaque (toothpaste is unnecessary). Rinse your teeth well with water. Tooth enamel has pores, and the pores need to be open for the chemical to penetrate.
2. 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 an 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 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.
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. White Strips don't work as fast as a dentist-made custom tray bleaching, (or in-office bleaching) but over time, you will get a result that will be close to that of a dentist, and you will save money too.
I recommend starting with with either the Classic or the Premium-Pro. The Classic works in 2 weeks and is about $1.80 a day. The Premium Pro works in 10 days and is about $2 dollars a day. The Premium and Premium Pro are likely to give you more sensitivity than the Classic.
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 using a custom-tray system or in-office bleaching. This is much more expensive, but the concentration of hydrogen peroxide is much higher and this works better on stubbornly-stained teeth.

This is my second day using this product and in fact, I have been seeing a little change. My teeth feel good and clean, AND of course, WHITE. It says on the pack not to brush your teeth before using the strips, but it just feels weird not to. So, I brush my teeth before and after using the strips BUT WITHOUT the toothpaste. I use one strip during the day and one before I go to bed. This gives me a feeling of satisfaction with my teeth before going to bed. I recommend this for those who want a younger whiter looking smile.
Great item for the money March 8, 2007
Without having to spend a great deal for professional whitening systems, these Crest WhiteStrips do a pretty decent job. I personally would not recomment do the whole 20 day program though, because after just 3 or 4 uses you will see some noticeable results without stripping too much of the enamel off your teeth.
