Having a brighter and whiter smile doesn’t just improve our appearance—it improves our confidence, too. So it’s no wonder we have so

many over-the-counter whitening products beyond just whitening toothpaste. One such product is a teeth whitening pen, which could be added to your oral care routine to enhance the brightness and whiteness of your teeth.

Here, we’ll discuss what they are, how to use them, and their effectiveness.

What Is a Teeth Whitening Pen?

Teeth can be stained from colored foods, such as berries, red sauces, coffee, tea, red wine, dark-colored sodas, and cigarettes.

Like whitening toothpaste, a teeth whitening pen fights these common stains—but it differs from toothpaste because of its size, portability, and

general convenience.
