What are crowns and why are they used?
A crown is a
restoration that covers, or caps, a tooth to restore it
to its normal shape and size. Its purpose is to
strengthen or improve the appearance of a tooth. A crown
is placed for a number of reasons:
||to support a large
filling when there isn't enough tooth remaining
||to attach a bridge
||to protect weak teeth
||to restore fractured
||to cover badly shaped or
||to cover a dental implant

Both the "look" and
function of your crowns are considered when choosing the
materials most suitable for you. Your dentist will
consider the tooth location, the position of the gum
tissue, the amount of tooth that shows when you smile,
the color or shade of the tooth and the function of the
Crowns are made from
a number of materials. Gold alloys or nonprecious
alloys, porcelain or ceramic, acrylic or composite resin
or combinations of these materials may be used.
Porcelain attached to a durable metal shell is commonly
used because of its strength. Crowns made entirely of
porcelain may look better; however, they usually aren't
as strong. In the process of making the crown, the
porcelain is colored to blend in with your natural

(often made of acrylic resins) are placed while the
permanent crown is made. If the shape or length of your
teeth are changed for cosmetic purposes, for example,
temporary crowns will allow you to become accustomed to
this change. They can also help you decide if you like
what you see or if there are any changes that you would
like made before the permanent crowns are placed.
the permanent crown is ready, the dentist puts it in
place and makes necessary adjustments. To see how your
crown will look, you can use a large mirror held at arms
length in various types of lighting. When you and your
dentist are satisfied with your appearance, the crown
will be cemented in place.
How do I take care of my crowns?
Brushing twice a day and cleaning between your teeth
daily with floss or interdental cleaners (specially
shaped brushes and sticks or picks) is especially
important when you have crowns. These measures remove a
sticky film of bacteria called plaque. It is especially
important to remove plaque from the area where the gum
meets the tooth (the sulcus). When plaque accumulates in
the sulcus, it can cause dental decay or gum disease. To
prevent damaging or fracturing the crowns, avoid chewing
hard foods, ice or other hard objects. It is also
important to visit your dentist regularly.
What will the
finished crown look like?
One of your dentist's main
goals is to create crowns that look like natural teeth.
To achieve this, a number of factors are considered such
as the color, occlusion or "bite," shape and length of
both your natural teeth and of the artificial crown.
Anyone of these factors alone can significantly affect
your appearance. If you have a certain look in mind for
your crown, discuss it with your dentist at your initial
visit. When the procedure is complete, your teeth may
not only be stronger, but they may be the attractive
feature of your face - your crowning glory.
