Dental crowns

Sometimes known as a caps, crowns are carefully fitted sleeves that sit over an existing tooth to protect it from further damage and to improve your overall smile.  

Crowns can hold cracked teeth together and support bridges. They can also cover discoloured teeth to improve the appearance.

You may need a crown if you are having a bridge fitted, as they create anchors to hold the bridge in place.

How is a crown fitted? 

Fitting your crown will usually involve two visits to see your Portway Dental Care dentist after an assessment of the tooth and its surrounding area, including the root. This may require an x ray. The tooth underneath must be as healthy as possible before the crown is fitted.

At the first visit your dentist will need to prepare the tooth to allow the crown to fit over the top of it and in line with the rest of your jaw so as not to affect your bite.

They will then take an accurate impression of your tooth to create a perfectly fitting crown that seamlessly sits alongside your existing teeth. A crown will usually take around two to three weeks to create in a dental laboratory, so before it can be fitted you will be provided with a temporary crown. This is usually made out of acrylic and is held in place with temporary cement to keep your mouth looking and feeling healthy while your crown is custom made. Your dentist will remove the temporary crown before attaching your unique crown using permanent dental cement.

What are crowns made from?

The application of crowns is one of the longest-standing dental procedures. We can date their use back to the 5th century and the ancient Etruscans, who used gold and silver to ‘cap’ problem teeth. Dental techniques have developed since then and in today’s practices crowns can be made from a variety of materials:

Metal, including gold alloy and other metal-based alloys

  • Zirconia
  • Porcelain
  • Porcelain fused to metal (known as PFM)
  • Porcelain fused to zirconia
  • Ceramic
  • Composite Resin

How long will a crown last? 

This is difficult to predict as it depends on your habits, lifestyle and oral care routine. Teeth grinding can put pressure on a crown, leading to cracks and possible damage. If you know that you suffer from clenching or grinding, speak to your Portway Dental Care dentist; they will be able to provide you with advice and possible solutions (such as a mouthguard) to help protect your crown and keep it looking its best into the future. A high frequency of sugar consumption and poor cleaning can lead to decay at the crown margins, which may then spread under the crown.

How shall I look after my crown? 

You can treat your crown like a normal tooth. While it does not require any particular care, remember that it acts as a sleeve over the top of your natural tooth and so decay and gum disease can still occur without a good oral health routine. Keep up regular visits to Portway Dental Care and remember to continue to floss or use an interdental brush around the tooth.

If you think that you require crowns, or would like further information on the procedure, contact Portway Dental Care and we would be pleased to help you.
