Whitening
procedures have effectively restored
the smile of people with stained,
dull, or discolored teeth.
The darker tissue of your teeth, the
dentin, can become exposed as the
outer layer of enamel is worn away
by the effects of aging or things
like caffeine and tobacco.
Food particles are naturally
attracted to a tooth's enamel by a
certain protein. Products like
coffee and tea, berries and soy
sauce are notorious for staining
teeth. Over time, teeth actually
become more absorbent and vulnerable
to staining from food and other
substances.
One type of stain-caused by
traumatic injuries, medications and
fluorosis-actually begins inside the
tooth; brushing and flossing don't
help. Another type of stain-one that
can be more easily attached by
brushing, flossing and rinsing-is
caused by external factors such as
foods.
More and more people today are
choosing tooth-whitening procedures
to reverse the effects of aging and
abuse from food and tobacco stains.
Some commercially available
"whitening toothpastes" can be
somewhat effective at removing
stains and making teeth a few shades
brighter. However, many of these
products have abrasive substances
that can actually wear away your
tooth's enamel.
Whitening agents actually change the
color of your teeth, but only are
effective on certain types of
stains. For example, bleaching
agents have a difficult time
removing brownish or grayish stains.
These products also are not as
effective on pitted or badly
discolored teeth, or on restorations
such as crowns, bridges, bonding and
tooth-colored fillings (porcelain
veneers or dental bonding may be
more appropriate in this case).
Professional whitening performed by
our office is considered to be the
most effective and safest method;
done properly, tooth whitening can
last as long as five years.
Over-the-counter whitening systems
are somewhat effective as long as
they are monitored and directions
followed closely.
