It's no secret that a lot of people desire a brighter smile, some of whom will take drastic measures from using tooth polish to trying a Magic Eraser. The value of the teeth whitening industry is set to reach $8.21 Billion by 2026, suggesting that people don't mind shelling out money to achieve the smile of their dreams. That said, not everyone can spend hundreds of dollars on professional whitening sessions, which is why at-home alternatives such as teeth whitening pens remain popular. If you're wondering whether getting a pearly white smile is truly as easy as swiping a pen over each of your teeth, here's what you should know.

How do teeth whitening pens work?

The process is pretty simple. Teeth whitening pens contain a whitening gel that's dispensed when you twist the base of the pen or click a button. Then you just paint the whitening gel onto your teeth and let it sit for the time specified on the instructions on your teeth whitening pen of choice, typically under a minute.

Teeth whitening pens generally contain hydrogen peroxide or carbamide peroxide (the same ingredients used by professional dentists) as active ingredients to help safely whiten your teeth, according to Amber Bonnaig, D.D.S., dentist at DentaQuest. Hydrogen peroxide and carbamide peroxide (which breaks down to release hydrogen peroxide when in contact with water) break down stain-causing compounds, making your teeth appear lighter. Typically, at-home whitening solutions contain about three to 20 percent of these active ingredients, while in-office systems can have anywhere between 15 to 43 percent, says Bonnaig. For best results, avoid smoking and drinking dark beverages as these impact the effectiveness of your teeth whitening with any teeth whitening solution including pens. (

You should always brush your teeth right before using a teeth whitening pen, according to Bonnaig. Otherwise, you run the risk of trapping plaque and bacteria between the film of the whitening gel and your teeth, which can lead to issues such as tooth decay, she explains. Additionally, it's best to consult with your dentist before jumping into any at-home teeth whitening solution, says Bonnaig. With their help, you can come up with a whitening plan that caters to your needs and won't put you at risk for sensitivity, gum irritation, and demineralization (the breakdown of tooth enamel aka the protective outermost layer of teeth).

Teeth whitening pens vs. other teeth whitening methods

Though teeth whitening pens are generally considered a safe means of whitening your teeth, they have some disadvantages compared to other options such as teeth whitening strips, says Bonnaig. "Teeth whitening pens lack protection to keep the film in place on teeth, meaning the whitening agent can move or detach, reducing consistent contact with teeth," she says. "Direct exposure of the product on the teeth is necessary for optimal whitening."

Of course, they also have their advantages. Using a teeth whitening pen only requires a few minutes of your time (compared to 30 minutes needed for whitening strips), they can be used on the go if necessary, and they're relatively affordable. If you do decide to opt for a teeth whitening pen, following the included instructions closely is super important to see the best results and minimize the chances of damaging your teeth in the process, says Bonnaig.
