Who doesn't want a nice set of pearly whites? Teeth whitening is big business and pens are among the newer products on the market. They've gained popularity due to their relative low cost, ease of use, and a general obsession with white teeth. These products do work; they’re not snake oil. But they’re also much less effective than treatments at a dentist. They're also not quite as good as teeth-whitening strips. That said, consistent use can lighten the shade of your teeth. Plus, they’re unlikely to irritate your mouth, they’re affordable, they’re easily portable, and they’re quite safe.

Active ingredients: Teeth-whitening pens these generally use a hydrogen-peroxide solution. Older pens sometimes used carbamide peroxide, but those aren’t quite as common. When you’re looking for a teeth-whitening pen, make sure that the product actually says what’s in it. That’s because there are few rules dictating the ingredients they can contain.
FDA and ADA: Teeth-whitening pens are not approved by the FDA or the American Dental Association. The FDA classifies these products as cosmetic and thus outside their sphere of concern, which means that nobody is really checking to make sure that they work. So you have to do a little bit of work yourself. Check to make sure that hydrogen peroxide is one of the ingredients in your pen.
Consistency: When using a fairly low-intensity whitening product like these, the most important thing is consistency in your application. Make sure to follow the manufacturer’s instructions and don’t miss any treatments. You’ll have to apply at least once a day for several weeks to see a result. It’s easy to get discouraged after a couple of days, but sometimes, good things take time.
