Bleaching or teeth whitening is ideal for people who have healthy, unrestoredteeth (no fillings) and gums. Individuals with yellow tones to their teeth respond best. But this cosmetic procedure is not recommended for everyone.
In-office bleaching provides the quickest way to whiten teeth. With in-office bleaching, the whitening product is applied directly to the teeth. These products can be used in combination with heat, a special light, or a laser. The most dramatic results — teeth generally get three to eight shades brighter — usually take several 60- to 90-minute in-office visits.
