Dental Crowns
Terry Ross
Dental crowns are generally used in cosmetic dentistry as a form of
dental restoration and are fitted over the remaining part of
the original tooth or used as a cap for dental implants.
Dental crowns are made of a variety of materials which include:
porcelain (generally used for front teeth as a straight
porcelain crown is very natural looking but they are not as
strong as bonded crowns)
porcelain bonded to metal
ceramic crowns which have the appearance of porcelain and the
strength of bonded so are suitable for any position in the mouth
Gold Alloy, a very hard wearing crown that is available in
gold or white.
Crowns are regularly used when teeth have been broken, have
been largely destroyed through dental decay or are excessively
worn. Crowns are molded in a dental laboratory and, unlike
basic filings, act as strengtheners for what is left of the
original teeth.
With more and more people turning to cosmetic dentistry to
create a perfect smile crowns have become widely used for
improving the appearance of healthy teeth. This is a practice
that isnt totally supported in the dental industry as a
portion of the original tooth has to be ground away to enable
the crown to be fitted in place.
When there is very little of the original tooth left it may be
necessary to insert a post into the root canal and cement into
place before fitting the crown. The post will add support and
help the dental crown stay in place.
As dental crowns are formed in a laboratory to get a crown
fitted requires 2 trips to the dentist. Initially your dentist
will take an impression of your teeth and provide you with a
temporary crown if required. The new crown will be fitted 1 2
weeks later and will be fixed into place using dental cement.
Crowns are made to match the exact color of your own teeth and
will appear completely natural. You yourself might be aware of a
crown for a few days after it is fitted but this will just be
short term.
The life of a crown depends on the level of dental care. Many
say a crown will last for 7 10 years but a well cared for
crown can last a lot longer. Crowns are extremely hard wearing
and durable but will not prevent further decay of the original
tooth!
The cost of dental crowns is generally covered by dental
insurance if they are used for restorative purposes. If you use
any form of cosmetic dentistry, including dental crowns for
appearance purposes you will normally have to cover the cost
yourself.
A single dental crown will cost between $500 and $1,100
depending on restorative requirements and the materials used.
