When a tooth is very heavily filled or badly broken down, a crown is usually needed to fix the tooth. A crown is a porcelain or metal 'cap' made in a laboratory, to fit over the patients existing tooth. This restores the tooth to its original shape, strengthens it and improves its appearance. The following is a typical example of the stages involved.

Appointment One

The dentist prepares the tooth for a new crown. A mould/impression is taken of the tooth, and sent to the laboratory. A temporary crown is made by the dentist, to cover the tooth for the 2 week period, while the new crown is being made in the laboratory.

Appointment Two

This appointment is usually about 2 weeks after appointment one. The temporary crown is removed, and the new one fitted, using dental cement.
