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.
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.
