This review is from: Crest Classic Whitestrips Teeth White 56 Strips 14 Day (Health and Beauty)

I am a dentist who recommends Crest-brand White Strips to my patients because 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. 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 revesible 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 in the office for two sessions and then use White 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).

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.

I am a dentist who recommends Crest White Strips to my patients because 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 to remove the layer of plaque. Your teeth have pores and the pores need to be open for the chemical to penetrate.

2. Use the strips twice per day for maximum efectiveness as stated on the box. The inner part of the strip has a chemical called carbamide peroxide (a 10% 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 will get whiter.

Disadvantages

1. The chemical can and probably will "burn" your gums. If you notice a burning sensation when you use the product, it is the chemical oxidizing (or burning) your gums. 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 normal again, resume treatment with the White Strips. Try to not ge the strip on your gums.

2. Your teeth may become senstiive during the two-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.

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. A dentist may also recommend an ultraviolet light bleaching which is costly, but works the best on these stains.

Crest White Strips work for the vast majority of people. They don't work as well or as fast as a dentist-made custom try bleaching, but over time, you will get a result that will be close to that of a dentist, and you will save money too. In any event, it is 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.

This review is from: Crest Classic Whitestrips Teeth White 56 Strips 14 Day (Health and Beauty)

I tried Rembrandt before, and their product worked but it wasn't very good. The best product I have tried is Crest Whitestrips Classic. I haven't tried the premium but it really does work. One thing to look out for though, is how you place the strips on your teeth. If you don't press it against the cracks, you end up bleaching the front and then you have vertical lines in your mouth of unbleached yellow.
