Root canal treatment (신경치료) is a dental procedure that removes infected or damaged pulp tissue from inside a tooth in order to relieve pain and preserve the natural tooth structure. It is typically considered when a cavity has progressed deeply, when a tooth has suffered significant trauma, or when persistent sensitivity or spontaneous pain suggests pulp involvement. The goal is to clean and seal the internal canals so the tooth can continue to function without further infection.

Because root canal treatment involves multiple steps — including diagnosis, canal shaping, disinfection, filling, and crown placement — verifying who actually performs each stage matters considerably. At a general dental clinic (치과의원), the procedure may be carried out by a general dentist or, in some cases, referred to or overseen by a specialist (전문의 in endodontics); clarifying this distinction before treatment begins is a practical step every patient can take.

The comparison table on this page lists clinics based on publicly available information such as staffing, equipment disclosure, and stated policies — it is not a ranking, and the order does not imply quality or recommendation.

Root Canal Treatment clinic checklist

1Confirm who performs the procedure
Ask directly whether the dentist who conducts your consultation is also the one who will perform the root canal treatment at every stage. Request written confirmation of the treating clinician's qualifications and, where applicable, whether an endodontic specialist is involved in complex cases.
2Check imaging and diagnostic equipment
Root canal treatment relies on accurate identification of canal anatomy; ask whether the clinic uses periapical X-rays and, for more complex cases, cone-beam computed tomography (CBCT). Understanding what diagnostic tools are available helps you have a more informed conversation with the dentist about treatment planning.
3Ask about magnification and canal instrumentation
Procedures performed under dental microscopes or loupes allow for more precise visualisation of canal systems, which is particularly relevant for teeth with multiple or curved canals. Ask the clinic whether magnification tools are routinely used and what type of canal instrumentation system they employ, as these are factual details clinics can clearly state.
4Obtain a written itemised estimate
Root canal treatment costs vary considerably depending on the tooth involved, the number of canals, whether a crown is needed afterwards, and the equipment used — no single figure applies universally. Before any procedure begins, request a written itemised estimate that separates diagnostic fees, the root canal steps, and any subsequent restoration, and ask what circumstances might lead to cost changes.
5Clarify the re-treatment and complication policy in writing
Ask the clinic to explain in writing what happens if a canal is missed, if infection recurs, or if retreatment becomes necessary at a later stage. Understanding the clinic's documented policy on these situations — including whether re-treatment fees apply and under what conditions — is a factual point you can verify before signing a consent form.

Warning signs

1Consultation conducted by non-clinical staff
If the person explaining the treatment plan, recommending the number of visits, or discussing fees is not a licensed dentist, the information you receive may not reflect an accurate clinical assessment of your specific tooth. Always confirm that a dentist has examined your X-rays and is the source of the treatment recommendation before proceeding.
2Pressure to decide or pay on the day of consultation
Root canal treatment involves a series of appointments, and a proper treatment plan requires reviewing diagnostic images and clinical findings — circumstances that do not call for an immediate financial commitment at a first visit. If you feel urged to pay for a full package or sign a contract before you have had time to review a written estimate, that is a reason to pause and seek a second consultation.
3Refusal to provide a written itemised estimate
Any clinic providing root canal treatment should be able to give you a written breakdown of expected costs before treatment begins, including what is and is not covered if additional canals or sessions are needed. A refusal or inability to provide this in writing makes it difficult for you to compare options or understand your financial commitment.
4No clear explanation of what happens if treatment fails
Root canal treatment outcomes can vary depending on the initial condition of the tooth, canal complexity, and how the tooth is restored afterwards — and retreatment or referral to a specialist may sometimes be necessary. If a clinic cannot or will not explain its documented process for handling complications or treatment failure, this is an important gap to address before consenting to care.

FAQ

How many appointments does root canal treatment usually take?

The number of visits depends on factors such as the severity of infection, the number of canals in the tooth, and whether a single-visit or multi-visit protocol is clinically appropriate for your case. Some straightforward cases may be completed in one or two sessions, while others require additional appointments for medication placement and monitoring. Your dentist should explain the expected treatment timeline after reviewing your diagnostic images.

Is it normal to feel discomfort after a root canal appointment?

Mild soreness or sensitivity around the treated tooth for a few days following each appointment is commonly reported and generally related to tissue inflammation during healing. However, the nature, duration, and intensity of post-treatment discomfort varies between individuals, and your dentist should provide specific guidance on what to monitor and when to contact the clinic. If you experience severe or worsening pain, swelling, or signs of infection, contact the clinic promptly rather than waiting for your next scheduled visit.

How can I confirm whether the dentist treating me is a specialist in root canal procedures?

In South Korea, you can ask the clinic to show documentation of the treating dentist's qualifications and whether they hold a specialist registration in endodontics or a related field. Clinics should be able to state clearly whether a general dentist or a specialist will be handling your case, particularly for teeth considered anatomically complex. The comparison table on this page includes staffing information where clinics have made it publicly available.

What affects the cost of root canal treatment, and how do I get an accurate figure?

Cost is influenced by which tooth is being treated (molars typically have more canals than front teeth), the extent of infection or damage, the equipment used, and whether a crown or other restoration is needed after the canal is sealed. Because these variables differ significantly between patients, any single quoted figure should be treated as a rough reference rather than a confirmed price. Request a written itemised estimate from each clinic you consult, and ask explicitly what additional costs might arise if treatment is more complex than initially assessed.

What should I do if symptoms return after root canal treatment is completed?

Recurring pain, swelling, or sensitivity after a completed root canal may indicate issues such as a missed canal, reinfection, a cracked tooth, or an incomplete seal — all of which require clinical evaluation rather than self-management. Contact the clinic that performed the treatment and ask them to review your case with updated X-rays before any further decisions are made. Understanding the clinic's re-treatment policy in advance, as noted in the checklist above, helps clarify what steps and potential costs would be involved.
