Gold inlays are a premium dental restoration used to repair moderate-to-large cavities or replace failing fillings. Made from high-quality dental gold alloy, gold inlays are known for their durability, precision fit, and long lifespan. While they may not match the natural color of teeth, gold remains a respected restorative material due to its wear resistance and biocompatibility.



What Is a Gold Inlay?

A gold inlay is a custom-made restoration fabricated in a dental laboratory and bonded into the prepared tooth. Unlike direct fillings (e.g., resin), gold inlays are indirect restorations—meaning they are shaped outside the mouth and then cemented into place. They are typically used when a filling is too large for direct restoration but a full crown is not necessary.

Gold’s physical properties make it ideal for areas that experience heavy chewing forces, such as molars.

Typical Price Range in Korea

The cost for gold inlay treatment in Korean dental clinics varies based on gold material composition, clinic reputation, and additional procedures required. On average, pricing is within the following range:

₩700,000 to ₩2,500,000 per tooth

Factors that influence the cost include:

• Gold alloy quality and percentage – Higher gold content increases price.
• Complexity of the restoration – Larger restorations covering more tooth surfaces cost more.
• Clinic location and technology – Premium clinics in central Seoul/Gangnam may charge more.
• Dentist expertise and laboratory fees – Custom fabrication and specialist skill affect price.

Actual fees can differ by clinic and patient needs.

What Affects Gold Inlay Pricing?

Several key elements influence total treatment cost:

• Gold Material Grade:
  Dental gold alloys vary in composition. Higher gold content and premium alloys cost more and may improve longevity.
• Number of Surfaces:
  A gold inlay covering multiple surfaces or deep cavities requires more fabrication and time, increasing costs.
• Lab Fabrication Fees:
  Skilled laboratory work contributes significantly to the total price.
• Clinic Standards:
  Clinics with advanced digital planning and premium materials may charge a premium.
• Additional Procedures:
  If tooth buildup, core build-up, or temporary restoration is required, the cost may increase.

Insurance Coverage in Korea

Gold inlays are generally considered premium restorative treatments and are not covered by Korean National Health Insurance. Unlike basic amalgam or resin fillings, patients usually pay the full cost out of pocket. If a gold inlay is recommended for functional reasons, partial coverage may be possible in rare cases, depending on insurance policy specifics.

Patients should verify coverage details before treatment.

Gold Inlays vs Other Restorative Options

• Amalgam (Silver) Fillings: Lower cost but less aesthetic and may expand/contract over time.
• Composite Resin Fillings: Tooth-colored and affordable but less durable for large cavities.
• Ceramic Inlays/Onlays: Highly aesthetic and strong but typically cost more than resin and can be similar or slightly higher than gold depending on materials.
• Gold Inlays: Excellent durability and fit, superior wear resistance, and long service life.

Each option has pros and cons. Gold is valued for durability and precision, especially where strength is a primary concern.

Longevity of Gold Inlays

Gold inlays are one of the most durable dental restorations. When placed correctly and cared for with regular dental checkups and good oral hygiene, gold inlays can last decades. Their resistance to wear and corrosion makes them especially suitable for molars and heavy bite forces.

Why Some Patients Choose Gold Inlays in Korea

Despite the rise of tooth-colored materials, gold inlays remain a respected option for several reasons:

• Exceptional longevity and wear resistance
• Superior marginal fit and adaptation
• Minimal risk of fracture compared with some ceramics
• Biocompatibility and gentle wear against opposing teeth

In Korea, many experienced restorative dentists are skilled in gold techniques, combining traditional craftsmanship with modern standards.

Conclusion

Gold inlay dental treatment costs in Korea typically range from ₩700,000 to ₩2,500,000 per tooth, depending on material, clinic, and complexity. While considered more expensive than traditional fillings, gold inlays offer excellent durability, precise fit, and long-lasting function—making them a strong choice for patients prioritizing performance and longevity. For accurate pricing and treatment planning, consult with a qualified dentist to discuss options suited to your dental needs.
