Dental crowns are tooth-shaped caps that improve both the form and function of patients’ teeth. Along with filling gaps in your smile, crowns cover implants, support bridges, and prevent weak teeth from shattering. While crowns can be made of various substances, including porcelain and resin, many modern dentists recommend using precious and semi-precious metals.
Metallurgy Meets Dental Care
Dental metallurgy refers to the art and science of using metals in dental care. A typical part of dental school curriculum, metallurgy involves making and compounding alloys for use in cosmetic treatments. Typically, dentists break metal alloys down into three categories. Made from precious metals, high noble alloys contain at least 40 percent gold and are widely regarded as the industry standard. The second category, noble alloys are made from semi-precious metals and have a noble metal content of 25 percent or more. Finally, non-noble alloys contain non-precious metals and are considered of lower quality.
A variety of metal types can be used to create dental crowns. Because pure metals lack the necessary physical properties, dentists tend to mix them with other alloys. For example, a crown that appears silver may actually be a mix of various white alloys. On the other hand, gold caps for teeth may actually be made from different precious alloys that are yellow in color. Other commonly used alloys include palladium, nickel, and chromium.
Not only can metal crowns be installed without removing much of the natural tooth structure, but they also hold up better than all-porcelain crowns. Able to withstand chewing and biting, metal crowns last longer and are unlikely to crack or break. In fact, many metal crowns last upwards of 40 years. Because of their metallic color, metal crowns are best suited to molars and other back teeth.
These days, many dentists prefer PFMs, or porcelain-fused-to-metal crowns over traditional gold crowns. As you might expect, PFMs are a hybrid of porcelain and metal. While the metal provides greater strength and longevity, the porcelain offers a natural-looking appearance that blends well with existing teeth.
