Crowns

What is a dental crown?

A crown is a form of tooth restoration which is used to provide extra strength for teeth that have become weakened or have been damaged. Also know as caps, they fit over the top of the teeth.

Why would I require a crown?

There are many reasons why you may need a crown, including:

  • You have a very large cavity
  • Your tooth has been weakened due to a large filling
  • Your tooth has been damaged due to an accident or injury
  • You've undergone a root canal
  • For aesthetic reasons

What are crowns made of?

There are various materials used to create crowns, including:

  • Precious and non-precious metals
  • Ceramics, such as porcelain

Popular crown material combinations are as follows:

  • All-metal crown
  • Metal bonded to ceramic
  • All-ceramic - The most popular choice
  • Porcelain bonded to zirconia

We can advise you on which is most suited to you.

How is a tooth prepared?

Before the crown is placed the tooth must be prepared, which involves:

  • Removing the decayed or damaged tissue
  • Cleaning the tooth thoroughly and shaping it in preparation for the new crown to fit over the top.
  • The dentist will create an impression of the tooth and send it to the laboratory.
  • Highly trained technicians will then manufacture your custom-made crown.

How long does the treatment take?

Treatment takes place over two sessions. The first appointment is the preparation of the tooth and the next is to attach the crown. The sessions usually take place around two weeks apart to allow time for the new crown to be manufactured.

What are post-crowns, and are they different?

If you've had a root canal you may be given a post-crown. This is to seize the crown in position in absence of the natural core of the tooth. One end of the post-crown is inserted into the root canal and the other end holds the crown in place. It is possible to build a core for a crown using filling material as an alternative to using a post-crown. We will explain which option is best for you.

Does it hurt?

Performed under local anaesthetic so you should not experience any pain or distress.

Will the crown be visible?

The crown will match the natural colour of your teeth to ensure it remains discreet when you smile. Temporary restorations will be more noticeable, but it will only be in place for 2 weeks.

How are crowns fitted?

Crowns are fitted to the teeth using dental cement. We will check that the appearance and fit of the crown is to your liking.

How long should a crown last?

If you maintain your crown correctly it should last for several years.

Will the crown be different to my normal teeth?

The crown can feel somewhat alien to begin with but your mouth should soon get used to it. If the crown still feels out of place after a time, we can check if it is possible to make any adjustments.
