The dentist will apply either a protective gel to your gums or a rubber shield to protect the oral soft tissues during bleaching. A bleaching agent is then applied to the teeth and a special light may be used to enhance the action of the agent.
At-Home Whitening System
There are several types of products available for use at home which can either be dispensed by your doctor or bought over the counter. Such as teeth whitening trays (mouth guards), strips, or paint-on products.

Zoom is a very simple procedure. Teeth goes through a brief cleaning first, then a peroxide-based gel is applied. Following the application, ultraviolet and blue visible light is used to activate the gel, accelerating the laser process by penetrating the teeth.
