IN-OFFICE BLEACHING BY PHILLIPS ZOOM
This procedure is called chairside bleaching and usually requires only one office visit. The dentist will apply either a protective gel to your gums or a rubber shield to protect your gums. Bleach is then applied to the teeth.
Peroxide-containing whiteners actually bleach the tooth enamel. They typically come in a gel and are placed in a tray that fits on your teeth. You may also use a whitening strip that sticks to your teeth. The concentration of the bleaching agent is lower than what your dentist would use in the office. If you are thinking about using an over-the-counter bleaching kit, discuss options with your dentist and look for one with the ADA Seal of Acceptance. That means it has been tested to be safe and effective for teeth whitening.
