What
are crowns?
A crown is a restoration that
covers, or "caps," a tooth to restore it to
its normal shape and size, strengthening and improving
the appearance of a tooth. Crowns are necessary when
a tooth is generally broken down and fillings won't
solve the problem. If a tooth is cracked, a crown holds
the tooth together to seal the cracks so the damage
doesn't get worse. Crowns are also used to support a
large filling when there isn't enough of the tooth remaining,
attach a bridge, protect weak teeth from fracturing,
restore fractured teeth, or cover badly shaped or discolored
teeth.
How is a
crown placed?
To prepare the tooth for a crown,
it is reduced so the crown can fit over it. An impression
of teeth and gums is made and sent to the lab for the
crown fabrication. A temporary crown is fitted over
the tooth until the permanent crown is made. On the
next visit, the dentist removes the temporary crown
and cements the permanent crown onto the tooth.
Will it look
natural?
Yes. The dentist's main goal is
to create crowns that look like natural teeth. To achieve
a certain look, a number of factors are considered,
such as the color, bite, shape, and length of your natural
teeth. Any one of these factors alone can affect your
appearance. All-ceramic crowns are preferable in the
smile region. In certain circumstances, crowns can be
made out of gold (or metal alloys) or a combination
of porcelain fused to metal.
Will the
crown feel different?
Because the shape of the crown will
be slightly different from the shape of your tooth before
it was crowned, you may be aware of it to begin with.
Within a few days it should feel fine, and you will
not notice it.
How should
I take care of my crowns?
How long your crown lasts depends
on how well you look after it. The crown itself cannot
decay, but decay can start where the edge of the crown
joins the tooth. Besides visiting your dentist and brushing
twice a day, cleaning between your teeth is vital with
crowns. floss or interdental cleaners (specially shaped
brushes and sticks) are important tools to remove plaque
from the crown area where the gum meets the tooth. Plaque
in that area can cause dental decay and gum disease.
