Zirconium vs porcelain crown

Zirconia is a polycrystalline ceramic based on zirconium dioxide, while porcelain crowns may use glass-based ceramic or porcelain layered over a stronger core. Some zirconia is highly translucent and some porcelain is reinforced, so the exact material matters more than the label alone.

The dentist examines tooth position, remaining enamel, bite forces, gum line, available space, colour demands, and any grinding habit. After preparation and scanning or impression, the laboratory fabricates the crown, which is tried in, adjusted for contacts and bite, and cemented when the fit and appearance are acceptable.

Arrange a review for a loose, cracked, painful, or rough crown, bleeding around its margin, or sensitivity that does not settle. A crown cannot correct decay or infection hidden beneath it without treating the underlying tooth.

Ask which ceramic formulation is proposed, why it suits this tooth and your bite, how much tooth structure must be prepared, and how colour and gum contours will be matched. Ask how the crown will be checked before cementation.
