Do Crest Whitening Strips Work? How does it work?

Updated on July 7, 2013

Back in 2001, Crest introduced its first whitening strip product. Since then, it has become the number one teeth whitening product in the United States. People have every right to be skeptical over whether this product works or not. After all, how on earth does a layer of strip make your teeth white in a few days? Those who don't understand the mechanics behind whitening strips may also wonder how it is able to coincide with dental habits such as brushing and flossing? Wouldn't such activities remove any effects the strip has on the teeth? There are many questions that remain unanswered.

In this hub article, I share my experiences of using this product. Please note that everyone has different experiences with these kinds of products. It may work for some, it may not work for others. For me, I was able to see a slight difference after applying the strips regularly for a week. Like you, I started to apply these strips because I was frustrated about my yellow teeth. I got slightly self-conscious over how my mouth appeared in photos. Technically, I could only blame myself because I never took care of my dental health that well back when I was a child.

How do whitening strips work?

This is a question that is frequently asked by customers. Most teeth bleaching procedures use the power of hydrogen peroxide to whiten your teeth. The chemical has special properties that aid the bleaching process. Once the strip is applied, the hydrogen peroxide does its job of removing the outermost layer of the teeth, reducing the amount of stains that exist on the surface. There is no cause for serious alarm as the layer is very thin. This will then leave the inner layer, where the white color appears from. At first, it's easy to assume that a whitening strip functions by adding layers of chemical on the teeth but that's not the case.

Another way in which strips aid your colorization progress is through a process called oxidization. Basically, the process of oxidization removes stains on the teeth by reacting with substances in the teeth enamel. Since it only works on certain types of stains, everyone will see different results after the first day of use.

One thing to take note of is the time span of the product. Once you stop applying the strips, your teeth may revert to its old appearance in a matter of days or weeks. The speed at which the effect disappears depends on a variety of factor such as the health of your teeth and gum tissues. At best, this product should be considered as a temporary solution, not a permanent one.

Alternative Methods

The best way to tackle any form of teeth color issues is to simply have healthy dental habits. At all times, you should brush and floss straight after a meal. Don't give it a second. Don't give the bacteria a chance to spread across your teeth surface and gum tissue. On top of dental habits, you should also watch what you eat and drink. There are certain types of food that cause stains on your teeth. For example, drinks like coke, coffee, and red wine are known to contain properties that cause stain buildup. If it is not possible to avoid those drinks, use a drinking straw to reduce the amount of contact between your teeth and the beverage liquid.

      Teeth whitening strips work but they DO NOT remove a thin layer of the tooth surface. Teeth are porous and the enamel (out layer) is basically translucent. Teeth whiteners penetrate the enamel to whiten the dentin below the enamel surface. Not the other way around! And while brushing and flossing will help with surfaces stains it may not keep stains from becoming incorporated in the teeth.
