Teeth Whitening Pens - What Are They? Do They Work?
Teeth whitening pens are the latest over-the-counter bleaching system. With a pen, the process of whitening your teeth has never been simpler! There are numerous pens on the market that are quick, not messy, and provide a system that can easily fit into one's busy schedule.
However, don't be fooled. Although teeth whitening pens offer a simple solution, they are not always effective and may cause uncomfortable side effects.
Teeth Whitening Pens vs Professional Whitening
Teeth whitening pens contains a low-concentration of whitening agents and is far less effective than high-concentration gel. The bleaching agent used is either carbamide peroxide or hydrogen peroxide. High-concentration gel contains 10-30 percent hydrogen peroxide, while low-concentration contains less than 10 percent.
Using a whitening pen typically involves applying the oxidizing agent to the teeth for as long as several hours a day for a period of 5 to 14 days. Results can vary, depending on which brand is chosen, with some people achieving whiter teeth in a few days, and others seeing very little results or no results at all.
Potential Side Effects
Whitening pens can slightly reduce tooth enamel, which may temporarily increase tooth sensitivity and mild irritation of the soft tissues of the mouth, particularly the gums. Tooth sensitivity often occurs during early stages of the bleaching treatment. Both of these conditions usually are temporary and disappear within one to three days of stopping or completing treatment.
Individuals with sensitive teeth and gums, receding gums, or defective restorations should consult their dentist prior to using a tooth whitening pen. People who are sensitive to hydrogen peroxide should not try any sort of bleaching product without first consulting a dentist. Prolonged exposure to bleaching agents may permanently damage tooth enamel. This is especially the case with home remedy whitening products that contain fruit acids.
The bottom line is to do your homework before purchasing and using any whitening pens.
