In-chair Whitening

Cosmetic tooth whitening traditionally relies on special gels and agents containing peroxide. There are a wide range of tooth-whitening products you can buy to use at home. However, dentists use gels and agents containing a higher concentration of peroxide in conjunction with a laser treatment for a much faster result. In fact, the whole whitening process can take less than two hours.

How in-chair whitening works

Once applied, the tooth whitening gel releases oxygen ions which go to work on the stained or discoloured teeth, lifting the pigmentation.

The laser accelerates this reaction, removing the stains faster. Because the laser can be used to target or focus on specific teeth, the dentist can treat each tooth separately. This is particularly useful when one tooth is more discoloured or stained than another.
