Teeth can be stained from food such as berries, red sauces, coffee, tea, red wine, soft drinks 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. Here, we’ll discuss what they are, how to use them, and their effectiveness.

How to use the Colgate Optic White teeth whitening pen?

Colgate’s Optic White Pen is a hassle free way to whitening your teeth. Follow these easy how-to steps for a whiter smile overnight:

  • After brushing your teeth just before bed, dry the top row of teeth by simply dabbing with a tissue. When your teeth are dry, the film adheres to your teeth better, for enhanced whitening!

  • Remove the cap and click the end of the pen until the gel is released. It may take a few extra clicks for the first time.

  • Apply a single, thin layer of serum to each tooth across the top row - and wait 10 to 15 seconds for clear film to form. Dry the bottom row of teeth and repeat the process.

  • The concentrated hydrogen peroxide film will stay on your teeth overnight while you catch those zzzs. The next morning, brush normally to remove the film and reveal your brighter, whiter smile.

  • To clean your pen, wipe the brush bristles with a dry tissue, do not use water. Firmly replace the cap until you hear a soft click to avoid hardening of the tip. If the pen dries out, click 2 - 3 times to dispense more serum and flex the brush to soften.
