What is a Crown?

  • Compared to fillings which just cover a small portion of a tooth, a crown (or cap) encases the entire visible portion of a tooth.
    • In effect, the crown acts as the tooth's new outer surface.
  • A dental crown is used when a tooth is broken or decayed to such an extent that fillings aren't able to repair the problem.
  • The crown is able to provide a protective shell around the damaged or decayed tooth to strengthen it, as well as to improve the appearance of the tooth.
    • They can also help restore a tooth to it's original shape, and are used commonly for teeth that have been broken.
  • While crowns come in different materials, the most common crowns typically have some mixture of porcelain in them to give them a look and feel similar to a natural tooth.

 


How is a crown able to be completed in one visit? 

  • The first portion of the visit involves reshaping the tooth and taking impressions to create the crown.
  • Typically a portion of your tooth will have to be removed for the crown to fit properly.
    • After the dentist reshapes your tooth, he will use a special material to create an impression of it. A stone model is made from the impression.
  • The doctor then scans the model and an image is sent to a computerized program where the crown is designed right there in the operatory.
  • Once all specifications are complete, the information is sent to a "milling" machine where the crown is created.
  • When the crown is finished, the doctor will ensure that it fits comfortably and matches the color of your teeth.
    • It is then bonded to the tooth rather than cemented. You now have your permanent crown in one visit!
