How teeth whitening pen works
Teeth whitening pens are an affordable option if you want to obtain whiter teeth. But the question is, do this whitening pen really works, so that it worth’s spend our money on it? Will the teeth whitening pen provide us better results that if we use for example teeth whitening strips or teeth whitening trays? In order to be sure of what the teeth whitening pen manufacturers promise us, we should understand the way that the teeth whitening pen is doing its magic.
First you must understand that all teeth whitening pens have almost the same ingredients, the percentage might differ although. So, each one has an applicator (many times in the form of a small brush). In order to whitening your teeth, the teeth whitening pens have also a bleaching compound. As you know if you already used other teeth whitening products, they all use as bleaching ingredient the hydrogen peroxide. The difference is that some producers decide to use different percentages of it. Carbamide peroxide can also be used. So, the first thing you have to do is to brush your teeth very good for some minutes, using your toothbrush. We want to have a clean surface of the teeth (this way you will see the stains better). Then simply apply the product on your teeth, in the way that is reaching all the surface of the teeth, even the spaces between them. Then you should let the gel stay on the teeth surface, in order to make his effect. The manufacturer will provide you informations, saying the amount of time that is best to keep the gel on the teeth.
Now let’s see how the bleaching gel does it effect. The stain appears on your teeth because the top layer of the tooth is worn down. Of course, if you drink coffee every day, the stain will be more pronounced. Also if you smoke you will have yellow teeth. So, the gel from the teeth whitening pen is actually working on the enamel of your teeth. After you finished applying it, you will probably have noticed that it took the shape of a thin film. If it has a higher percentage of hydrogen peroxide you will get your results a lot sooner, but remember that it can cause also to have sensitive teeth. After some minutes, you need to wash the gel away, so that it can’t affect your gum.
