How Do You Use a Teeth Whitening Pen?

Short answer

Brush your teeth, twist the base of the pen until gel reaches the brush tip, and paint a thin layer onto the front of each tooth. Let it dry and do not rinse. Philips' directions for the Zoom whitening pen are to apply it twice a day for two weeks and avoid eating or drinking for 30 minutes after each use.

Step by step

1. Brush first. Philips recommends brushing before each application for the best result.
2. Twist the base. Turn it until the gel appears on the brush tip.
3. Smile wide. Pull your lips back so they stay off your teeth.
4. Paint a thin layer. Brush the gel onto the front surface of each tooth you want to whiten.
5. Let it dry. Keep your lips apart for a moment while it sets. Do not rinse.
6. Wait 30 minutes. No eating or drinking for 30 minutes after.

How many times a day do you use a whitening pen?

Twice a day for two weeks, according to Philips. Each pen holds up to 30 applications, enough for a full two week course.

What is in the Philips Zoom whitening pen?

A 5.25% hydrogen peroxide gel, which Philips describes as a formula brushed directly onto the teeth for touch-ups on the go.

When is a whitening pen the best choice?

• Touch-ups after a tray course, to keep your shade bright.
• Travel and work, because there are no trays to carry.
• Before an event, as a final boost. See how far ahead to start whitening.

For a bigger change in shade, pair it with a tray system such as Opalescence Go or Philips Zoom NiteWhite.

Can you eat or drink after using a whitening pen?

Wait 30 minutes, as Philips directs. That gives the gel time to work on the teeth.
