One question worth asking

Is there a version of this crown my plan covers fully, and what is the difference?

All-ceramic crown

CrownsMajorD2740

D2740. The most common crown today, tooth-colored with no metal, such as zirconia.

A crown is a cap made in a lab or milled in the office that covers the whole tooth above the gum. It is used when a tooth is cracked, heavily filled, or treated with a root canal. Codes differ by material: all-ceramic, porcelain fused to metal, all metal, or resin. A three-quarter crown is the same idea but leaves one healthy wall of the tooth untouched.

The tooth is numbed and trimmed down on all sides, an impression or scan records the shape, and a temporary cap is worn while the lab makes the real one. At the second visit the crown is checked for fit and bite and cemented on. Codes divide by material, and all-ceramic or gold versions are often treated as upgrades over the standard one. Most plans file this as Major. What they actually pay varies by plan.
