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. That is why dentists take
an impression. 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.
If you have a certain cosmetic look in mind for your
crown, discuss it with your dentist at your initial visit.
When the procedure is complete, your teeth will not only
be stronger, but they may be more attractive.
What are Veneers?
Porcelain veneers are ultra-thin shells of ceramic material,
which are bonded to the front of teeth. This procedure
requires little or no anesthesia, and can be the ideal
choice for improving the appearance of the front teeth.
Porcelain veneers are placed to mask discolorations,
to brighten teeth, and to improve a smile. Highly resistant
to permanent staining from coffee, tea, or even cigarette
smoking, the wafer-thin porcelain veneers can achieve
a tenacious bond to the tooth, resulting in an esthetically
pleasing naturalness that is unsurpassed by other restorative
options.
Why a porcelain veneer?
Porcelain veneers are an excellent alternative to crowns
in many situations. They provide a much more conservative
approach to changing a tooth's color, size, or shape.
Porcelain veneers can mask undesirable defects, such
as teeth stained by tetracycline, by an injury, or as
a result of a root-canal procedure, and are ideal for
masking discolored fillings in front teeth. Patients
with gaps between their front teeth or teeth that are
chipped or worn may consider porcelain veneers. Generally,
veneers will last for many years, and the technique has
shown remarkable longevity when properly performed.
Why crowns and not veneers?
Crowns require more tooth structure removal, hence, they
cover more of the tooth than veneers. Crowns are stationary
and are customarily indicated for teeth that have sustained
significant loss of structure, or to replace missing
teeth. Crowns may be placed on natural teeth or dental
implants.
What is the difference between a cap and a crown?
There is no difference between a cap and a crown.
How long do crowns last?
Crowns should last approximately 5-8 years. However,
with good oral hygiene and supervision most crowns
will last for a much longer period of time. Some damaging
habits like grinding your teeth, chewing ice, or fingernail
biting may cause this period of time to decrease significantly.
How should I take care of my crowns?
To prevent damaging or fracturing the crowns, avoid chewing
hard foods, ice or other hard objects. You also want
to avoid teeth grinding. 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. |
