Dazzle Your Family and
Friends with Whiter Teeth
Tooth whitening is a
very common cosmetic dentistry procedure that lightens teeth
and helps to remove discoloration and stains. It is probably
the most popular cosmetic dental procedure because it can
significantly improve the appearance of teeth at much less
cost and inconvenience than other cosmetic dental techniques.
A thin coating forms on your teeth daily and this coating
picks up stains. The outer layer of each tooth, called the
enamel, contains pores that hold stains. Tooth whitening is a
procedure that needs to be repeated more than once to achieve
the desired effect.

Why Whiten?
The most common reasons for stained teeth are tobacco,
tea/coffee, and aging; all of these stain the surface of
the teeth. Stains can affect the inside of the tooth, also
and are called intrinsic stains. Intrinsic stains can be
caused by exposure to too much fluoride as a child while
your teeth were developing. Antibiotics containing
tetracycline taken during the second half of pregnancy can
also cause intrinsic stains. |
How Does it Work?
Before teeth are whitened, cavities need to be treated because
the solution used to whiten teeth can penetrate tooth decay
and reach the inner areas of the tooth. Whitening will not
work on exposed tooth roots because there is no enamel on the
roots. Crowns and porcelain veneers cannot be whitened. Tooth
whitening works best on teeth that have been stained by food,
drinks or age.

Over-the-counter
teeth whitening products sold in drug stores are not
usually recommended by your cosmetic dentist because
they can produce unnatural-looking results, and the
store-bought trays may not fit your teeth properly. |

Whitening can be done
at
home or in your dentist's office. For whitening done
in the
office, the dentist will usually take photographs your teeth
making it easier for him to monitor how the process is going
for you. Whitening in the office typically takes just under an
hour and may involve four to six visits.
For whitening at home, your cosmetic dentist will direct you
to use trays custom-made from impressions taken of your teeth.
Whitening at home usually takes two to three weeks.
