9+ Types: What are Dental Crowns Made Of (2024)?

Dental restorations designed to fully encapsulate a damaged or weakened tooth can be fabricated from a variety of materials. These coverings, often referred to as “caps,” are cemented onto the tooth, providing protection and restoring its shape, size, strength, and appearance. For example, a severely decayed molar might require such a restoration to prevent further deterioration and restore functionality.

The choice of material significantly impacts the restoration’s durability, aesthetics, and biocompatibility. Historically, gold alloys were a popular choice due to their strength and longevity. Modern materials offer a wider range of options, allowing for restorations that closely mimic the natural appearance of teeth. The successful application of a full coverage restoration relies heavily on selecting the most appropriate material for the specific clinical situation.
