Here is how this laser tooth whitening technique is done. Laser tooth whitening is a term used for power bleaching, using a potent bleaching gel and an activating light. It has the strength to lighten the color of the teeth dramatically in a single session. Though for lasting effect, the patient either needs to have several appointments, or to follow up the in-office procedure wearing at home bleaching trays. The following are photographs of this procedure:

First, the teeth need to be exposed and isolated. The light has to have access to all the visible surfaces of the teeth, so retractors are placed to gently pull the lips and cheeks away.
A napkin is placed over the lips and cheeks to shield them from the whitening gel. Then a coating is placed over the gums. The bleaching gel is irritating to soft tissues, and so it must be kept confined to the teeth with these techniques.
Then the Zoom light is focused on the teeth. The gel penetrates into the teeth, and it is activated by the light. The gel releases oxygen inside the tooth, and the oxygen provides the bleaching action.
At the end of the appointment, the teeth are dramatically whiter.
