Hello.

We are Seoul Dia Dental Clinic, located at Magok Station, where we care about both the beauty and health of your teeth.

In the previous four-part installment, we discussed why a crown is necessary after root canal treatment.

Today, we will address the question many people search for first before deciding on root canal treatment.

"How much does root canal treatment cost?"

Because certain high-cost treatments exist, it is true that concerns about cost often come first when people think of dental treatment. T.T

Let us be honest.

The cost of root canal treatment can vary considerably depending on the location and condition of the tooth.

Fortunately, root canal treatment is covered by national health insurance!

Today, Seoul Dia Dental Clinic will realistically organize the costs of root canal treatment and the criteria for insurance coverage.

Root Canal Treatment Is Covered by National Health Insurance

Root canal treatment is covered by national health insurance.

However, the cost varies depending on the location of the tooth.

The more roots a tooth has, the more complex the treatment is, and the higher the cost tends to be.

1. Front Teeth (Anterior Teeth)

[ Approximately KRW 10,000–15,000 ]

Front teeth often have one root, so treatment is relatively straightforward.

After insurance coverage, treatment is available at around the low KRW 10,000 range.

2. Premolars

[ Approximately KRW 15,000–20,000 ]

With one or two roots, premolars are slightly more complex than front teeth.

3. Molars

[ Approximately KRW 20,000–30,000 ]

Molars often have three or four roots, making them the most complex and generally the most expensive.

Please note that the amounts above refer to the insurance-covered cost of the root canal treatment itself.

Additional charges may apply if further procedures are needed. ^-^

When Additional Costs May Apply

1. X-ray Imaging

X-rays are needed before and after root canal treatment.

Depending on the condition, this may include panoramic or periapical X-rays, but these are covered by national health insurance, so they are not usually a major financial burden.

2. CT Imaging

A CT scan may be added when the root structure is complex or a more detailed examination is needed.

It is not necessary for everyone and is recommended only when the dentist determines that it is needed.

3. Pulp Capping

This is a procedure in which the pulp is covered to preserve the nerve while it is still viable.

As a step before root canal treatment, this procedure may resolve the problem without root canal treatment in some cases.

It may be covered by national health insurance.

4. Root Canal Orifice Preparation / Septum Formation

When the crown portion of the tooth has been extensively damaged, preparatory work may be needed before treatment.

Additional costs may arise during this process.

When Insurance Does Not Apply

Magok-dong Dental Clinic_Core and Post

Root canal treatment itself is covered by national health insurance, but the following procedures or materials may be provided as non-covered services.

1. Crown Materials

Whether insurance applies to a crown depends on the material.

Zirconia and PFM crowns are non-covered. However, metal crowns for molars may be covered for people aged 65 or older or in cases that meet certain conditions.

2. Resin Core / Post

After root canal treatment, the core used to fill the inside of the tooth or the post used to support it may be non-covered, depending on the material.

3. Retreatment

This refers to treating a tooth that has previously undergone root canal treatment.

Retreatment is often more difficult than the initial treatment and may cost more.

Insurance coverage is possible, but additional procedures may increase the number of non-covered items.

How Much Does Treatment Cost in Total, from Root Canal Treatment to a Crown?

Here is a realistic overview of the total cost many people are curious about.

<Based on front teeth>

Including root canal treatment (covered) + crown (non-covered)

Approximately KRW 300,000–500,000

<Based on molars>

Including root canal treatment (covered) + crown (non-covered)

Approximately KRW 500,000–800,000

The amounts above are estimates and may vary depending on the materials selected and the dental clinic.

Therefore, it is important to receive accurate information about the cost before treatment begins.

Are You Delaying Treatment Because of the Cost?

Magok-dong Dental Clinic_Root Canal Treatment Costs

Some people delay treatment because the cost of root canal treatment and a crown feels burdensome.

But let us speak realistically!

If a tooth that needs root canal treatment is left untreated, the inflammation may spread further, and the treatment area may expand, often resulting in higher costs.

In severe cases, extraction followed by an implant may be necessary, and that cost is considerably higher than root canal treatment plus a crown.

This is not only about the cost. Losing a natural tooth, which is a valuable part of your body, can also cause significant inconvenience in daily life.

Even if the cost of root canal treatment feels wasteful right now, saving your natural tooth is ultimately the wisest choice.

At Seoul Dia Dental Clinic, we provide accurate estimates before treatment.

We proceed transparently without unexpected additional costs, so you do not need to worry.

We are happy to provide convenient consultations through Naver TalkTalk or reservations.
