The process by a dentist, also known as bleaching chair, first involves applying a protective gel on the gums to protect against the harmful effects based on hydrogen peroxide gel. After protection of the gums, the gel is applied, but not before removing the plaque on the tooth surface.
When the gel is applied, the laser is also used on the area to be bleached to create a chemical reaction in the gel to cause the desired effect. The depth of the spots determines the amount of time the gel is allowed to remain on the teeth before being rinsed.
