Detailed explanation-1: -Gold tooth crowns can be placed on any tooth that’s been damaged through decay, breakage or general trauma. In most cases, however, gold tooth crowns were used placed over molars at the back of the mouth, as they are less visible and therefore more subtle.
Detailed explanation-2: -Dentistry commonly uses Gold in its dental alloys with a karat value ranging anywhere from around 10 to 22. On average, the typical yellow-colored gold dental crown is around 16 karat (67% gold). Besides gold, this type of alloy may also contain amounts of palladium, platinum and silver.
Detailed explanation-3: -Gold dental work is also highly resistant to oral acid, bacteria, and to corrosion, so it’s one of the most long-lasting methods of dental restoration available. Gold crowns and other gold-based dental work can easily last decades with proper care, and it’s not unheard of for gold restorations to last 50 years.
