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 a crown made of?
Crowns can be made of porcelain or porcelain bonded to metal.
- Porcelain crowns
These crowns are made entirely out of porcelain. They look very natural.
- Porcelain bonded to metal
These consist of a metal base and then porcelain is applied in layers over it.
Your dentist will give you a local anaesthetic to numb the tooth and prepare it for the new crown.
Once prepared, a mould of your tooth is taken in a putty-like material so that the dental technician can make a crown that fits the tooth perfectly. It may take one or two weeks for the crown to be ready, so your dentist will fit a temporary one. At the second appointment, your dentist will take off the temporary crown and fix the new one permanently in place.
What are the benefits?
- A crown is strong and can look and feel exactly like a natural tooth
- The colour and shape can be matched to your own teeth
- Depending on the strength of the tooth underneath, a crown can last for many years
- Crowns can also improve the appearance of unsightly or discoloured teeth
