Crowns and Bridges

What is a Crown?

A dental crown is a tooth-shaped cover (cap) that is placed over a tooth to restore its shape, size, and strength, and/or to improve its appearance. Once cemented into place, crowns fully encase the entire visible portion of a tooth that lies at or above the gum line.

Why Choose a Crown?

To cover severely discolored teeth
To restore a tooth that has been severely worn down or broken
To support a dental bridge
To cover a dental implant
To protect a weak tooth (for instance, from decay) from breaking or to hold together parts of a cracked tooth

What Types of Crowns Are Available?

Crowns can be all ceramic, porcelain-fused-to-metal, or all-metal:

All-ceramic or all-porcelain crowns typically provide the best esthetic color match and may be more suitable for people with metal allergies. However, they are not as strong as porcelain-fused-to-metal crowns and they wear down opposing teeth a little more than metal crowns do. All-ceramic crowns are a favored option for front teeth.
Porcelain-fused-to-metal crowns can be fabricated to match the color of your adjacent teeth. However, these crowns can abrade the opposing teeth a little more quickly than metal crowns. The crown’s porcelain portion can also chip or break off. These are generally appropriate for either front or back teeth.
All-metal crowns consist of gold alloy, a base-metal alloy (for example, nickel or chromium), or other kinds of alloys (for example, palladium). All-metal crowns generally last longer, rarely chip or break, and are a satisfactory solution particularly for out-of-sight molars.
