Dental gold crowns are tooth-shaped caps made from a gold alloy (mix of metals). They're incredibly durable, lasting for decades and able to withstand strong chewing forces. This makes them ideal for back teeth, especially for people who grind their teeth. However, they are not very attractive due to their gold color.
For a more natural look, other crown materials like porcelain are preferred for front teeth. But if durability is your top concern, discuss gold crowns with your dentist.
