Molar root canal treatment is needed when the nerve (pulp) of a molar tooth becomes infected due to deep decay, trauma, or repeated dental procedures. Because molars typically have three or more root canals and more complex anatomy, treatment is more involved than for single-root teeth. In Korea, prices vary based on the number of canals, clinic standards, and any additional diagnostic or restorative needs.



Average Cost Range for Molar Root Canal Treatment

At most dental clinics in Korea, the typical cost for a molar root canal procedure falls within the following range:

₩400,000 – ₩600,000 per tooth

This estimate is based on standard endodontic treatment of a molar with three canals. Prices may differ slightly depending on clinic location, dentist expertise, and case complexity.

What Factors Influence the Cost?

Several variables can affect the final price of molar root canal therapy:

• Number of Canals Treated:
  Molar teeth often have 3–4 canals. Each canal adds time, materials, and complexity to the procedure.
• Anatomy Complexity:
  Curved, narrow, or calcified canals require more skill and time, and may involve advanced tools.
• Imaging Requirements:
  Standard X-rays are usually included, but 3D imaging (CBCT) for diagnosis or planning may be an additional fee.
• Dentist Skill and Specialty:
  Endodontic specialists often charge higher fees than general dentists due to advanced training.
• Clinic Location:
  Clinics in central Seoul or premium districts often have higher fees than those in smaller cities.
• Additional Procedures:
  If a retreatment is needed (previous root canal re-treatment), or broken instruments need to be removed, the cost may increase.

Insurance Coverage in Korea

When a molar root canal is necessary for medical reasons—such as pain, infection, or abscess—this treatment is generally partially covered by Korean National Health Insurance. The reimbursement depends on clinical diagnosis and insurance policy terms.

However, fees for advanced imaging, specialist surcharges, or premium materials are usually paid out of pocket.

Patients are advised to verify coverage details with both their dental clinic and insurance provider before treatment.

Additional Treatment Costs to Expect

The root canal procedure itself may not include subsequent restorative work. Common additional fees can include:

• Permanent Filling or Core Build-Up:
  Required after the root canal to seal the tooth.
• Dental Crown:
  A crown is often recommended for molars after root canal therapy to strengthen and protect the tooth.
  Crown costs vary depending on material and clinic.
• Follow-Up Visits:
  Minor fees may apply for post-treatment checks.

These restorative costs are typically billed separately from the root canal fee.

Molar Root Canal vs Extraction

While extraction is sometimes considered when treatment costs are a concern, root canal therapy allows the natural tooth to be saved. Preserving the tooth helps maintain chewing function, prevents shifting of neighboring teeth, and avoids future costs for replacements such as bridges or implants.

Longevity and Aftercare

With appropriate restoration and oral hygiene, a molar that has undergone root canal treatment can last many years. After therapy:

• Follow the dentist’s restoration plan (often a crown).
• Maintain good oral hygiene.
• Attend regular dental check-ups.

Conclusion

In Korea, a molar root canal procedure typically costs ₩400,000 to ₩600,000 per tooth, depending on canals treated, complexity, and clinic standards. Partial national health insurance coverage generally applies for medically necessary treatments, while additional diagnostic or specialist fees are usually out of pocket.
