A crown is needed if a tooth has been fairly extensively damaged by:

  • Tooth decay
  • Fracture or breakage of a section of a tooth
  • An old large filling that is coming apart or failing

A crown would be the solution to these problems. A crown is a replacement outer covering, not unlike a thimble, that fits over and strengthens a tooth and restores its appearance and function.

Types of Crowns

There are different types of crowns for different purposes. The most common type of crown is a porcelain crown with a ceramic or sometimes a metallic core for strength. These crowns are very strong and very closely reproduce the look of a natural tooth. The metal inside the crown is often an alloy of gold. On the back teeth, or molars, especially where it is difficult to see, a gold crown is often the perfect choice because of its strength and durability (average durability is 20-40 year with good hygiene care).


  • Shaping the tooth to remove the decay in or around it
  • Re-sculpturing the tooth to provide an ideal fit for the crown
  • Making a digital image of your teeth in order to create a custom-made crown
  • Making a temporary crown out of tooth colored resin and fitting it onto the tooth during the interim period when the permanent custom-made crown is being created Applying the permanent crown (when received from the lab) by removing the temporary crown and fitting the permanent one onto the tooth
  • After ensuring that the crown has the proper look and fit, the dentist cements it into place

Expected Service of the Crown

Crowns can be expected to last for a number of years providing the person performs good oral hygiene and has regular professional care.
