Which Dental Crown to Choose?

19 / 02 / 2018

Crowns and Onlays (sometimes referred to as caps) are artificial coverings that are used to improve the appearance, restore the shape, size and function of teeth that are heavily broken down and filled.

  • A Dental Crown is used for many reasons, some of which are:
  • To protect weak teeth from breaking or to hold together parts of fractured teeth.
  • To restore broken or severely worn teeth.
  • To encase and support teeth with large fillings where not enough of the natural tooth remains.
  • To support and hold a Dental Bridge securely.
  • To improve the appearance of misshapen or heavily discoloured teeth.
  • To cover Dental Implants
  • To make cosmetic modifications for aesthetic improvement.

How long does crown treatment take?

Crowns usually take two visits. The first visit is usually the longer; to prepare the tooth and take the necessary records for the crown to be made from. The tooth is smoothed down to a smaller version of itself to allow the laboratory enough space to construct the customised restoration. Impressions are taken and sent to the laboratory. A temporary crown is usually made to protect and restore the tooth in between the appointments and temporarily bonded on

What are the risks?

Whilst a crown is a strong long term restoration it is important to be aware that not all crowns can be provided without potential complications. The underlying tooth is normally already heavily broken down and compromised so there a chance that it can still become carious and break. Also if the tooth does cause any problems afterwards it may require root canal therapy and then potentially a new crown with a post or it may need to be removed all together.

What is a Dental Crown made from?

The 3 major types of dental crowns are:

  • Porcelain Fused to Metal crown (PFM)

This is a crown that utilises the latest porcelain technology to bond to a high fusing precious metal substructure. This crown is constructed by a skilled team of technicians to ensure a high quality crown is produced. It is strong due to the metal substructure and the colour of the porcelain over the top is matched with your existing tooth colour as close as possible.

  • Gold Crown

On back teeth where appearance is not so critical a gold crown is usually the academic material of choice. The amount of tooth preparation and drilling for this type of crown is very minimal in comparison with the others and is the most tooth friendly restoration. A high content gold alloy is used which is the most hard wearing and long lasting of all crown types.

  • Ceramic Crown

Pressable ceramics are used to produce a highly aesthetic and life-like appearance for your crown. There are different types of ceramics that your dentist can discuss with you that would best your individual circumstances. This can be a happy medium between the above two. Tooth can be prepared removing only where necessary and keeping the margins above the gumline, where at all possible like the gold, to reduce the amount of overall preparation. There are no metal or alloys in this crown and its lifelike nature and strength make it ideally suited for any tooth in the mouth including back teeth. The colour of this crown is matched as closely as possible with your existing tooth colour.
Your Dental Team will discuss with you what the best option is based on your teeth and individual requirements.

How to look after your crowns?

Crowned teeth do not need any special care, but will still require a regular, Dental cleaning routine at home and routine visits to your Dentist and hygienist.

Therefore, continue following good Oral Hygiene practices – brushing your teeth twice a day, one of which should be last thing at night and flossing once a day – especially around the crown area where the gum meets the tooth.
