Porcelain Crowns

A crown can prevent a weak tooth from breaking and hold parts of a cracked tooth together.

Dental crowns can also:

  • restore a tooth that’s broken or severely worn down
  • cover and support a tooth with a large filling when there isn’t a lot of natural tooth left 
  • hold a dental bridge in place
  • cover severely discoloured teeth
  • restore a dental implant
  • be used for cosmetic reasons to make your smile look better

What types of crowns are available?

Permanent crowns can be made from different materials including metal, porcelain, resin and ceramic.

  • All-ceramic or all-porcelain crowns can be matched to your natural tooth colour better than other crown types. Less of your tooth will need to be drilled away too, which helps keep the tooth strong. These crowns are a good choice for front and back teeth.
  • Gold crowns are very strong and long-lasting. They’re most often used on back teeth where the sight of the gold isn’t as noticeable.
  • Porcelain-fused-to-metal dental crowns can be matched to the colour of nearby teeth (unlike crowns made entirely from metal). They were used a lot before ceramic and porcelain crowns were made. These crowns can be a good choice for front or back teeth.

 How long do dental crowns last?

On average, dental crowns last 5-15 years. The life span of a crown depends on how much wear and tear it’s exposed to and how well you care for your teeth. It’s helpful to avoid grinding or clenching your teeth, chewing ice, biting your fingernails and using your teeth to open packaging.

 Does a crowned tooth need special care?

No, but just because a tooth is crowned doesn’t mean it’s protected from decay or gum disease. You’ll need to keep caring for your teeth and gums, including brushing your teeth at least twice a day and flossing once a day – especially where the gum meets the crown. It can also help to use an antibacterial mouth rinse. Regular dental hygienist appointments are a chance to get your crown checked and cleaned thoroughly.
