Dental Crowns
A dental crown, or dental cap as it is also
known, is a cosmetic dentistry procedure, used when the tooth has
been badly damaged or decayed. This particular cosmetic dentistry
procedure is used when the tooth decay or damage is too severe to
be filled successfully. Dental crowns or dental caps are tooth-shaped
coverings that are placed over the damaged or decaying tooth. Dental
crowns can also be used to hold a bridge in place or to cover badly
discolored or misshaped teeth.
Types of Dental Crowns
Three types of dental crowns:
· Metal Dental Crowns are made of gold
alloy, palladium, nickel alloy, or chromium alloy. Metal dental
crowns
are ideal for and often used on the back teeth.
· Ceramic Dental Crowns look like normal
teeth and are ideal for use on the front teeth.
· Porcelain fused to metal (PFM) Dental
Crowns are stronger than ceramic crowns and
also look like normal teeth. Like ceramic dental crowns,
PFM dental crowns are ideal
for use on the front teeth.
Dental Crown Procedure
If the tooth decay or tooth damage is severe
enough, the cosmetic dentist may choose to perform a root canal
before placing a dental crown on the tooth, in which case the cosmetic
dentist may need to build a foundation for the dental crown. This
is known as a "post-and-core" foundation.
Before a dental crown can be placed on a tooth,
the cosmetic dentist files the tooth to create a fit. Once this
is completed, an impression of the tooth and all surrounding teeth
is made. A temporary acrylic dental crown is placed on the tooth
to protect it while the permanent dental crown is being made.
When the permanent dental crowns are ready
the temporary crowns are removed and the permanent dental crowns
attached. The finished dental crown will last anywhere from seven
to 40 years.
Cost of Dental Crowns
The final cost of getting a dental crown
will always depend on the type of dental crown being used, the number
of dental crowns involved, and the area of the country in which
the procedure is performed.
