What are crowns made of?

Metal Alloy – Dentists may recommend using a metal alloy (a mixture of metals) for a crown, such as gold alloy (noble or high noble) or a base-metal alloy. Metal crowns tend to last longer than other crown materials.

Porcelain – This type of crown is the most natural-looking (includes ceramic and glass-like materials) since its color and translucent design closely matches surrounding teeth.

Porcelain Fused to Metal – A porcelain fused to metal crown is when porcelain covers a metal crown, which creates a more natural-looking crown. 

Common CDT codes for Crowns:
