What is a Crown?

A crown (also called a cap) is a man-made cover that protects the tooth. It may be used to restore and preserve decayed, broken or cracked teeth. Crowns can also improve your overall appearance.

Why you may need a crown?

Your dentist may advise you to get a crown if you have:

  • A decayed tooth that needs to be restored to its normal shape and size
  • A cracked tooth with large cavities or worn fillings
  • A poor-fitting crown
  • A root canal treated tooth
  • A cosmetic problem
  • A bite problem

Types of Crowns:

Metal:These are made of gold or other metals. It is very strong and won’t break. Because this type isn’t tooth colored, it may not be the best for a front tooth.

Porcelain: This is a tooth colored crown made of porcelain or re-inforced resin. It comes in a range of shades to blend with your other teeth. This type of crown may be more likely to chip than a metal crown.

Combination: This is a porcelain fused to metal crown. With porcelain on top re-inforced by metal in the inner surface of the crown. The metal makes the base stronger than a porcelain crown, but it is not as strong as a metal crown.

Tooth Preparation

Before preparing your tooth for a crown, your dentist may numb the area with a local anesthetic. Then, the tooth is reduced and shaped. Any decay is removed. Your tooth may also need rebuilding if larger parts are missing. A mold is taken for the prepared tooth and the surrounding teeth. A temporary crown is applied to protect the prepared tooth between visits.
