What is a crown?
A crown is an artificial restoration that fits over the remaining part of a prepared tooth, making it strong and giving it the shape of a natural tooth. A crown is sometimes known as a ‘cap’.
What is the difference between a veneer and a crown?
A crown encases the entire tooth, a veneer just its front side. A fundamental difference between veneers and crowns is how much of the tooth they cover over. Crowns typically encase the entire tooth, whereas veneers only cover over its front surface (the side that shows when the person smiles).
Why would I need a Crown?
Crowns are an ideal way to repair teeth that have been broken, or have been weakened by decay or a very large filling. A crown could be used for a number of other reasons, for example:
- you may have a discoloured filling and would like to improve the appearance of the tooth
- you may have had a root filling and need a crown to protect what is left of the tooth
- it may help to hold a bridge or denture firmly in place.
What is a crown made of?
Crowns can be made of a variety of different materials and new materials are continually being introduced. Some of the most popular options are listed below.
Porcelain bonded to precious metal: this is what most crowns are made from. A precious metal base is made and then porcelain is applied in layers over it.
Porcelain: these crowns are made entirely out of porcelain and are not as strong as bonded crowns. But they can look very natural and are most often used for front teeth.
All-ceramic: this modern technique offers a metal-free alternative, which can give the strength of a bonded crown and the appearance of a porcelain crown. Therefore it is suitable for use in all areas of the mouth.
Glass: these crowns look very natural and can be used anywhere in the mouth.
Gold-alloy crowns: gold is one of the oldest filling materials. Today it is used with other metal alloys to increase its strength, which makes it very hardwearing. These crowns are silver or gold in color.
How is a crown prepared?
The dentist will prepare the tooth to the ideal shape for the crown. This will involve removing a layer of the outer surface, leaving a strong inner core. The amount of the tooth removed will be the same as the thickness of the crown.
Once the tooth is shaped, the dental team will take an impression (mould) of the prepared tooth, one of the opposite jaw and possibly another to show the way you bite together.
The impressions will then be given to a dental technician, along with information about the shade to use and any other information they need.

Placing a dental crown requires a lot of tooth trimming.
