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, and all the years of staining with tea, coffee, and red wine etc. is removed in a matter of an hour; revealing truly white teeth that enhances the perfection of a smile. We use the Philips Zoom teeth whitening system.
