A tooth whitening pen looks like a regular pen except that it does not contain ink, instead it contains an active ingredient known as hydrogen peroxide. Many people, especially women, will already be familiar with this chemical as it can be used to bleach the hair.
The tooth whitening pen features a small brush at the end. The idea is to apply the brush to your teeth each night for a period of two weeks. There is no need to worry about swallowing the active ingredient because it is very quick drying.
What Kind Of Result Can I Expect?
The tooth whitening pen contains only a low concentration type of hydrogen peroxide. This is another reason why the risks are low. Therefore, you can expect to gain one or two shades of whiteness using this technique. If you are looking for better results then you should consider high concentration gels, either for use at home or by your dentist.
An advantage of using your dentist is two-fold. Firstly, they can protect your gums against the corrosive effects of the high concentration gel. Secondly, they can use a high intensity light to accelerate the bleaching process. It is not uncommon to gain three to give shades of whiteness in a single session. However, the treatment costs considerably more than the tooth whitening pen.
