When the tooth structure has been weakened due to disease or wear it may be necessary to cover the whole remaining tooth with a crown. This is a restoration that ‘caps’ the remaining tooth to protect it. In some cases crowns can be used to enhance the aesthetics of a tooth. Crown can be made of various materials like porcelain or metal.

What does a crown involve?

Your dentist will first check if the tooth is still alive, and if the nerve has died the tooth may need root canal treatment first.

The dentist will file the tooth all round by about 2mm to create space for the crown. An impression with a soft mouldable material is then taken to send to the laboratory for them to make your crown. The initial visit can take about an hour for the preparation and the impressions. Your dentist will make a temporary crown on your tooth while the dental technician makes the permanent made.

Your permanent crown is normally fitted 1-2 weeks later. Your dentist may need to make small adjustments to it, so it is comfortable when biting.

Onlay Restorations

In certain situations just a simple filling does not provide all the protection your tooth will need. Onlays cover some or all of the chewing surface of the tooth to protect its integrity. These restorations can be made of metal (gold), composite or porcelain.
