Crest Whitening Strips

By Cody Scholberg

Crest Whitestrips are great teeth whitening products. They all work the same way, and they come in many different forms. The strips contain hydrogen peroxide, which is the very effective bleaching agent found in many teeth whitening products.

Teeth whitening products traditionally contained abrasive materials which were designed to scrub the teeth; the idea was to remove any discoloring particles. The teeth whitening product essentially functioned as sandpaper for the teeth. The teeth were supposed to return to their natural white color, but it was soon discovered that many people did not naturally have white teeth.

This led the way for the development of hydrogen peroxide; this chemical literally bleaches the teeth white. It does not remove discoloring particles, but it stains them instead. This process is far more effective than using abrasive material. Now, all teeth whitening products use a bleaching agent like hydrogen peroxide except for teeth whitening toothpastes.

Whitestrips are made with an adhesive material which is designed to stick to the teeth. It will last for at least the whole thirty minutes of treatment in all the products except the Daily Whitening Multicare and the Daily Whitening Multicare with Tartar Control products, which will last at least the whole five minutes of treatment.

Out of all teeth whitening products, Crest Whitestrips do work exceptionally well. You can buy them either over-the-counter or non-over-the-counter in many different strengths and varieties, each with a hydrogen peroxide content of anywhere from six to fourteen percent.

Despite their great uses, Crest Whitestrips have some problems, too. First, since they lay flat across the teeth, they do not get into the cracks and grooves in between the teeth. This leaves the user with a type of "zebra" effect. Second, the Whitestrips are not made with great adhesive material, so they slide off the teeth very easily. Therefore, users are prohibited from doing much with their mouths (eating, drinking, smoking) if they want the strips to stay on the teeth. Crest came out with a product which stays on the teeth better, called Crest Whitestrips Advanced Seal.

Crest Whitestrips are excellent products for whitening teeth, and their placement is easy to control, so users can avoid touching the strips to the gums, avoiding burns. Despite their flaws, Crest Whitestrips remain among the best teeth whitening products.
