There are many types of dental crowns that you can choose, ranging from common metals to gold and silver. Let’s read on with The East Rose Dental to learn more about different types of dental crowns to make the best decision!

1. Porcelain-fused-to-metal crowns

This type of crowns has a metal inner structure and a porcelain cover. Usually, the inner structure is made of Cr-Co alloy, Cr-Ni alloy, or Titanium.

This is an affordable option. However, it comes with a huge disadvantage which is after a few years of using, the crowns will lose their original brightness.

In addition, the metal may oxidize. The extent and speed of oxidation depend on the type of metal and other factors. This causes the roots to have a metallic shine and the gumlines to look bruised, affecting the overall appearance.

As a result, porcelain-fused-to-metal crowns are not commonly indicated for the restoration of front teeth.

2. Precious metal crowns or golden crowns

Precious metal crowns or golden crowns:

  • Are among the most durable types of crowns. They can last from several dozens of years to a lifetime.
  • Don’t change color at the base so don’t affect the natural pinkish color of the gums.
  • Have sturdy linings that don’t crack or break even if they’re extremely thin.
  • Are highly accurate, thus, prevent cavities, chipped teeth, stuck food particles, bacterial buildups, etc.
  • Have a naturally beautiful color thanks to the inner golden shine (compared to the normal dull shine of metals).
  • Have high biocompatibility, are comfortable for your natural teeth and gums, non-toxic, don’t oxidize, don’t have a taste or odor.
  • Minimize the loss of tooth tissue, resulting in stronger teeth.
  • Have anti-inflammatory properties as gold is naturally antibacterial.

  • Precious metal crowns and golden crowns don’t have the disadvantage of the aforementioned porcelain-fused-to-metal crowns. However, as they are made of precious materials and require more advanced technique, they are more expensive.

In a nutshell, precious metal crowns have the inner structure made of precious metals such as gold or platinum.
