How to Use Colgate Optic White Overnight Teeth Whitening Pen?

Based on the description listed on the Colgate website, the Colgate whitening pen was designed with an emphasis on making it simple to use; that’s why one of the standout features of the Colgate Whitening Pen is its convenience.

Wondering how to use the Colgate whitening pen? Here are the steps to follow:

  1. To start, click the back of the pen to dispense the gel.
  2. At this point, you can brush the gel onto the parts of your teeth that you are trying to whiten.
  3. This is then left on overnight and results in visibly whitened teeth after a week of consistent use.
  4. A residual film from the whitening gel might remain on the teeth in the morning following application; to get rid of this, all you need to do is gently brush your teeth.
  5. To make sure that you keep your whitening pen in good shape and can continue to use it, close the cap until it clicks to prevent the whitening gel from drying out.
