Using a laser with a whitening gel is an in-office
whitening system. The translucent whitening gel
is applied to the tooth and a laser light is
used to activate whitening crystals that absorb
energy from the light and penetrate the tooth
to increase the lightening effect on the tooth.
The length of time in the cosmetic dentist's
chair depends on the degree of discoloration
you have, usually 1-2 hours.
Advantage: One visit is usually
all it takes for a bright smile.
Disadvantage: The sudden change
of color is likely to be noticed by those around
you immediately. This is the more expensive of
the procedures available, but also the quickest.
