Zirconia and all-ceramic crowns contain no metal alloys, making them metal-free restorations. That said, it is worth asking your dentist about other components, including any post, core, or cement, involved in the placement of a crown.
What Zirconia and Ceramic Crowns Are Made Of
Both zirconia and ceramic crowns are tooth-colored and resist corrosion and rarely cause allergic reactions. Zirconia is a strong ceramic made from zirconium dioxide. Other all-ceramic crowns are made from porcelain-type materials. The bottom line is that neither contains the metal alloys found in traditional full-metal or porcelain-fused-to-metal crowns, which is why they’re preferable for patients with metal sensitivities.
Ask About the Whole Restoration
A crown is more than its outer shell. If a tooth needs a post or core to support it, or a dental implant is involved, those parts can contain metal. It’s thus important to ask what each component of your treatment is made of.
