Preparation is the process of re-shaping a tooth in order to restore it.
Teeth are prepared for silver (amalgam) and tooth colored (composite) fillings.
The shape of the preparation must be correct in order to properly restore
Usually when a dentist
talks about tooth preparation (also called a prep), he is referring to
the process of reshaping a tooth (or teeth) for crowns. The preparation,
in a sense, is like the foundation for a house; the finished crown will
only be as good as its foundation allows. If not enough tooth is removed
then, when materials are added back in construction, the crown will be
"fat", and the color will not be correct, in the case of porcelain. I feel
that under preparation is the biggest mistake made in preparing teeth for
crowns and bridges. In addition, if the sides of the tooth preparation
are not parallel then the crown or bridge will not stay on correctly.
This picture shows that
when materials are added back in the construction of a crown on a properly
prepared tooth, that the crown will restore the tooth to it's original
size and shape.
