In-office Teeth Whitening is a chair-side bleaching process that lightens the discoloration of tooth enamel through the use of a special light and a whitening gel containing hydrogen peroxide.
First, a protective coating is painted onto the patient's gums surrounding the treatment area. This protective coating is allowed to harden and serves to shield the gums. The whitening gel is then applied to the teeth, and a special light is applied to enhance the whitening process. This light aids in activating the hydrogen peroxide and helps it penetrate the surface of the tooth.
Use of in-office whitening light increases the whitening gel's effectiveness by 26%, providing whitening improvement by up to eight shades. Post-treatment, the dentist can provide the patient with a tooth tray, home whitening kit, and instructions for touch-ups.
