White resin fillings—also known as composite fillings—are one of the most common and conservative dental treatments used to restore teeth affected by cavities, minor chips, or old discolored fillings. In Korea, these treatments are widely available at dental clinics and are valued for their natural appearance and durability.



What Is a White Resin Filling?

A white resin filling is a tooth-colored restorative material made of composite resin. It bonds directly to the tooth structure and is shaped to match the original contour of the tooth. Because it blends with natural tooth color, white resin fillings are often preferred over traditional silver (amalgam) fillings.

Average Price Range in Korea

The cost of white resin fillings in Korean dental clinics can vary depending on several factors. On average, prices typically fall within the following range:

₩50,000 to ₩150,000 per surface

Prices are generally based on the number of surfaces restored:

• Single-surface filling: Lower end of the range
• Multiple surfaces: Higher cost due to additional material and time required

Actual fees may differ by clinic, region, and dentist expertise.

What Influences the Cost?

Several factors affect the final price of white resin fillings in Korea:

• Number of Surfaces Treated: More surfaces require more material and chair time.
• Tooth Location: Fillings on molars or difficult-to-access areas may cost more.
• Clinic Reputation and Technology: Clinics with advanced equipment or cosmetic emphasis may charge higher fees.
• Dentist Experience: More experienced practitioners may set higher prices.
• Material Quality: Premium composite materials may increase the cost slightly.

Insurance Coverage in Korea

White resin fillings for decay are partially covered by Korean National Health Insurance when they are done for medical necessity. However, cosmetic resin restorations or replacements of old fillings for aesthetic reasons may not qualify for full coverage.

Patients should check with their dentist and insurance provider to confirm the exact coverage and out-of-pocket costs.

White Resin vs Other Filling Types

Compared to silver (amalgam) fillings, white resin fillings offer superior aesthetics and better bonding properties. While amalgam fillings may still be used in certain cases, patients increasingly choose composite resin for visible teeth because it matches the natural tooth color.

Another alternative—ceramic or porcelain inlays/onlays—offers higher durability and precision but at a higher cost than resin fillings.

Longevity and Maintenance

With proper oral hygiene and regular dental checkups, white resin fillings can last many years. They may require replacement sooner than ceramic restorations, especially in high-wear areas like chewing surfaces. Regular dental exams help detect any signs of wear, cracks, or recurrent decay early.

Conclusion

White resin fillings in Korean dental clinics typically range from ₩50,000 to ₩150,000 per surface, depending on complexity, number of surfaces treated, and clinic factors. Resin fillings offer a natural, tooth-colored restoration option for decay and minor defects. Before treatment, patients should consult their dentist regarding pricing, coverage, and the most appropriate restorative option for long-term oral health.
