Crowns are used to restore tooth/teeth which are fractured, decayed or lost. Crowns are devices which are fixed on to the tooth or implants by using cement and can be removed only by a dentist.
The procedure involves reduction of the involved tooth/teeth. If a large portion of the tooth structure is missing because of trauma or caries. Then a separate restoration is placed to establish an ideal tooth preparation. Then an impression is taken of the prepared area and a temporary crown is placed
Why Is a Dental Crown Needed?
A dental crown may be needed in the following situations:
  • To protect a root canal treated tooth to prevent it from breaking
  • To restore a malformed, discoloured or fractured tooth
  • To cover and support a tooth with a large filling when there isn't enough tooth structure left
  • To cover a dental implant
Types of Crowns
Temporary Crown - A Temporary Crown is made up of acrylic, can be used as a temporary restoration until a permanent crown is delivered
Permanent Crowns - Permanent Crowns includes all metal, porcelain-fused-to-metal, and all ceramic
Types of Permanent Crowns
Metal used is a base metal alloy-nickel or chromium. This rarely chip or break and lasts longer. The only drawback is the metallic colour and so is used to restore back teeth.
Metal-ceramic dental crowns can be color matched to your adjacent teeth (unlike the metallic crowns). . These crowns can be a good choice for front or back teeth
All-ceramic dental crowns provide the best natural color match than any other crown type. All-ceramic crowns are a good choice for front teeth.
