What is a Crown?
A crown is a custom lab made restoration that fits over the remaining part of a prepared tooth making it strong, improving appearance and giving it the shape of a natural tooth. A crown is sometimes known as a 'cap'.
What is a Post Crown?
This is used when very little tooth structure remains but where there is a root still present. This root must have been root treated (nerve removed). A post can be put into the root and then used to support a crown.
