Porcelain Crowns

A crown is a type of dental restoration which completely caps or encircles a tooth or dental implant. Crowns are often needed when a large cavity threatens the ongoing health of a tooth. They are typically bonded to the tooth using a dental cement. Crowns can be made from many materials, which are usually fabricated using indirect methods. Crowns are often used to improve the strength or appearance of teeth.

The most common method of crowning a tooth involves using a dental impression of a prepared tooth by a dentist to fabricate the crown outside of the mouth. The crown can then be inserted at a subsequent dental appointment. Using this indirect method of tooth restoration allows use of strong restorative materials requiring time consuming fabrication methods requiring intense heat, such as casting metal or firing porcelain which would not be possible to complete inside the mouth.

The most common crown restoration placed by most general dentists today utilizes a metal lining covered with porcelain. These types of restorations are not as natural in appearance because light is not able to pass through porcelain-metal crowns as it does with a natural tooth, resulting in an opaque or flat looking tooth. Often times these types of traditional crowns leave a dark or gray line next to the gum-line. Dr. Thomas is proud to offer a natural looking alternative-all-ceramic, non-metal crown! With these newer restorations you will notice the “life-like” appearance that mimics natural teeth and does not produce the black gum line so common with so many porcelain-metal crowns.
