You may have seen in-chair whitening described as “laser” whitening. In most cases, the whitening is done by a peroxide gel, and a light may be used as part of some in-chair systems.
What happens during treatment?
After an examination, your gums are covered with a protective barrier. A whitening gel is applied to the teeth for a set time, sometimes with a light. The process is usually repeated in cycles during one appointment.
Is it safe?
When your teeth and gums have been checked and treatment is supervised by the dental team, whitening is generally well tolerated. The most common side effects are tooth sensitivity and gum irritation, which usually settle within a few days. People with untreated decay, cracked teeth, gum disease or exposed roots may need other treatment first.
What results can I expect?
The amount of change varies. Existing crowns, veneers and fillings do not whiten, and results fade over time. Some people are advised to combine in-chair whitening with take-home trays.
