Gold crowns are an excellent choice, if having an entirely white smile is not a top priority. They are ideal for back teeth where they are less visible. A gold crown has many advantages, not the least of which is durability, withstanding heavy forces from chewing. They do not chip or break, making them a long-lasting dental restoration. Gold crowns are made of cast gold, a technique that has been in existence for over a hundred years, and are still the most successful restoration.
Crowns such as all-metal and porcelain-fused-to-metal, are made using specific types of alloys. No pure metals are used in these restorations, not even gold. This is because for dental applications, the physical properties of alloys are superior in strength and durability.
