When Is Gold Used in Dentistry?

March 10, 2020

Gold is a softer metal that has been used for centuries in dentistry from everything from a denture base to dental crowns dating back thousands of years [1]. Today, gold is still used to restore damaged teeth in some instances, and offers advantages that other filling materials can’t. When is gold used in dentistry, and why would you consider gold for a dental restoration today?

Smaller Dental Restorations

The majority of gold used in dental fillings today is actually a mixture of gold with other metals, called gold alloy. However, these metals typically do not contain mercury such as amalgam filling restorations. In some cases, such as with direct gold fillings, pure gold is used to fill teeth. However, pure gold is generally only appropriate for teeth that don’t need to withstand biting or chewing forces.

Gold is an excellent material for smaller dental restorations, such as small cavities and inlays and onlays. It doesn’t require as much removal of your natural tooth structure to place the material, and these restorations are resistant to fractures. Your dentist can let you know if gold is a consideration for your smaller dental restorations!

Full and Partial Dental Crowns

You may also have the option of using gold for full and partial dental crowns. Dental crowns are used to restore teeth that have been damaged as a result of decay, teeth grinding, or an accident. Very durable and resistant to damage, these dental crowns can be used to provide dental restorations that last many years.

Gold alloy would be used to fabricate the crown in a lab and then your dentist would place it to restore your tooth. Electroformed pure gold may be used in some dental crown applications, making a highly durable dental restoration with superior performance [2].

The Pros and Cons of Gold

Gold is very durable in dentistry applications and can last for 20 years with the right care [3]. Reactivity to this metal is low, but if you have a metal allergy or sensitivity, you should inform your dentist, as you may not qualify for this restoration material.

While gold is an excellent restoration for damaged teeth, it is more expensive and needs to be placed by a dentist experienced in working with gold. In addition, gold won’t match your natural teeth, and many patients want a more uniform look for their smile. If aesthetics aren’t an issue, you may consider gold for your dental fillings or crowns!
