How does Teeth Whitening Gel work?

Updated 6 hours ago by Marlou Quilicol

The main ingredient in teeth whitening gel is generally Hydrogen peroxide or a close derivative called carbamide peroxide. These molecules are made up of hydrogen and oxygen. As the molecule interacts with your teeth the hydrogen and oxygen break apart causing a deep cleaning action. The molecules will become active when exposed to your teeth, higher temperatures, or Ultraviolet light (UV). This is why normal hydrogen peroxide (for cleaning wounds) is sold in a dark (brown) bottle - to prevent the sun from penetrating, and the instructions say to store in a cool place.

A good quality teeth whitening gel will be fresh (so it has not had time to break down from environmental elements) and is sold in packaging that does not allow light to penetrate.

In the case of AutoBrush®, our teeth whitening Pen are packaged in its own box. This eliminates the gel’s interaction with UV light and outside elements.
