Crowns

What are dental crowns?

Teeth are often restored using  fillings of silver or composite plastics. These materials are more than adequate to restore  the part of the tooth that has been destroyed by tooth decay. However, there comes a point where there is so much  damage to the tooth  structure ,that it cannot hold  a filling. The ideal treatment for such type of teeth are the usage of crowns.  A Crown is a cap like covering that is fitted over a tooth to restore its natural size and shape. A crown strengthens the tooth, protects the remaining tooth structure and can improve appearance. The tooth is trimmed so that the cap can be placed over the tooth like a hat on a head. The crown  also forms an important  unit  of a  fixed bridge which is used for the replacement missing of teeth.  

What are they made up of?

Crowns can be fabricated from different materials depending on the location, color and function of the tooth. Metals are more commonly used to fabricate  the crowns for posterior teeth, although material such as ceramics and other plastic like material are also used

Why do we need crowns?

A crown is placed for a number of reasons:

  • To restore fractured teeth.

  • To protect weak teeth from fracturing.

  • To support a large filling when there isn't enough tooth remaining (the tooth structure becomes weakened and can no longer support the filling).

  • To conceal badly shaped or discolored teeth, Gaps between teeth and also crooked teeth
