Root canal therapy—also known as endodontic treatment—is a procedure used to save a tooth when the nerve (pulp) becomes infected or damaged due to deep decay, trauma, or repeated dental work. In Korea, root canal pricing varies depending on the tooth type, number of canals, treatment complexity, and clinic standards.



What Is Root Canal Therapy?

Root canal therapy involves:

• Diagnosing the affected tooth with clinical exams and X-rays
• Administering local anesthesia
• Removing infected or inflamed pulp tissue
• Cleaning and shaping the root canal system
• Filling and sealing the canals with biocompatible material

After the root canal, a filling or crown is typically placed to restore strength and function.

Typical Root Canal Treatment Costs in Korea

In Korean dental clinics, root canal therapy pricing is generally based on the number of root canals and tooth location. Typical cost ranges are:

• Front tooth (1 canal): ₩200,000 – ₩400,000
• Premolar (2 canals): ₩300,000 – ₩500,000
• Molar (3 or more canals): ₩400,000 – ₩600,000

These ranges are estimates and may vary depending on the clinic, dentist expertise, and complexity of treatment.

Factors That Influence Pricing

Several elements affect the final cost:

• Tooth Anatomy: More canals and curved or calcified canals increase difficulty and time.
• Complex Cases: Retreatment of a previous root canal, fractured instruments, or complex anatomy can increase cost.
• Imaging Needs: Advanced imaging like 3D CBCT scans may incur additional fees.
• Dentist Skill Level: Endodontic specialists often charge more than general dentists.
• Clinic Location: Clinics in central Seoul or premium areas may have higher base fees.

Additional Costs to Expect

Root canal therapy fees often cover only the endodontic portion of treatment. Other potential costs include:

• Initial Consultation and X-rays: Basic diagnostic fees
• 3D CBCT Imaging: Additional if needed for complex cases
• Temporary Filling: Placed between visits if multi-session treatment is required
• Permanent Restoration: A filling or core build-up after root canal
• Crown Placement: Recommended for long-term protection and strength (separate cost)

Crown placement and restorations are usually not included in the root canal fee and are billed separately.

Insurance Coverage in Korea

Root canal therapy performed for medical necessity—such as infection, pain, or abscess—is typically partially covered by Korean National Health Insurance. The exact portion covered depends on clinical diagnosis and insurance rules.

Premium materials, specialist fees, or cosmetic considerations are generally paid out of pocket.

Patients should verify coverage details with both their dentist and insurance provider before treatment.

Root Canal vs Tooth Extraction

Root canal therapy is recommended when a tooth can be saved and restored to function. Extraction may be considered when:

• The tooth is fractured beyond repair
• Bone support is insufficient
• Infection cannot be controlled

Saving the natural tooth with root canal therapy often prevents the need for more expensive replacement options like implants or bridges.

Longevity and Aftercare

With proper restoration and care, root canal–treated teeth can last many years. After treatment:

• Follow your dentist’s restoration plan (often a crown).
• Maintain good oral hygiene.
• Attend regular dental check-ups.
• Avoid excessive biting on hard foods initially.

Root canal therapy has a high success rate and is a predictable way to preserve natural teeth.

Conclusion

In Korea, root canal therapy generally costs between ₩200,000 and ₩600,000, depending on the number of canals and complexity of the tooth. Additional fees for imaging, restoration, and crown placement are usually separate. Partial national health insurance coverage may apply for medically necessary cases, while premium materials and cosmetic enhancements are paid out of pocket. Discuss your specific needs and pricing details with your dentist to determine the best treatment plan for your oral health.
