Dental Crown

What is a dental crown?

A dental crown is a cap that covers the tooth to protect the tooth from further breakdown. 

Dental Crown Procedure

The tooth is shaved or prepared just enough to compensate for the material added back to the tooth. An impression is taken of the prepared tooth, and the temporary crown is made to last for one to two weeks until the permanent crown is fabricated from the dental lab. The more recent advance is the use of digital technology to capture the tooth’s image and make the crown the same day. The permanent crown is made to look like the natural tooth.

Applications of Dental Crown

When you have a large Dental Filling or broken tooth, the crown protects the remaining weak tooth structure. The larger the filling, the weaker the remaining tooth structure, more likely the remaining tooth structure will break. With aging, there is more wear and tear from chewing, grinding, acidic food, making the teeth weaker. Any back tooth with a root canal should be crowned as the chance of fracture is more than 50%.
