Budget for root canal treatment through the final crown
This South Korea root canal total cost calculator compares two dentist-provided plans for the same single tooth: preservation and extraction followed by an implant.
The first appointment bill may omit retreatment extras, post/core work, a crown or additional surgery.
Separate covered patient payments from non-covered charges to estimate the cash needed through the final restoration.
Root canal treatment addresses the pulp and tissues around the root tip to help retain natural tooth function.
Whether preservation or extraction is appropriate requires a dentist’s examination and diagnosis.
A lower cost or a longer duration entered here does not establish suitability or treatment success.
The insurance context is South Korea, with the 2026 sources below; this is a planning estimate, not medical advice.
When this comparison helps
- You received separate root canal and crown quotes and need the complete budget
- Your dentist discussed both retreatment and extraction with an implant
- Your family wants to budget for a possible additional operation
Why tooth position and canal count do not set a universal price
Anterior, premolar and molar record the tooth described in the quote.
Anatomy and required procedures can differ even for the same position, so the calculator does not assign a canal count from position.
Leave the count at zero when unknown and use the provider’s total patient-payment quote.
Procedures and complexity
A treatment course can include consultation, imaging, irrigation and filling.
HIRA has also published a separate fee revision for complex C-shaped canals.
Older published amounts or a universal retreatment multiplier do not establish the charge for your current plan.
What the patient actually pays
A full covered fee includes both insurer and patient shares.
A patient-payment quote already reflects the insurance calculation and must not be multiplied by the share rate again.
Align the included procedures before comparing quotes, even from the same provider.
Separate covered patient payments from non-covered charges
The default input is the actual covered patient payment for the entire root canal course on one tooth.
Do not enter the full covered fee from a statement as though it were your patient payment.
Ask for an itemized plan and exclude procedures that you enter in separate extra-cost fields below.
Optional calculation from confirmed full covered fees
Full covered fees = canal count × full-course covered fee per canal + shared tooth fees
Estimated patient share = round(full covered fees × confirmed share percentage ÷ 100)
The per-canal amount is supplied and confirmed by your provider; it is not a fee schedule supplied by this site.
Shared consultation or examination fees must not already be included in the per-canal amount.
The optional result requires a known canal count and confirmation that one percentage applies to the full entered fee amount.
Article 19 and Appendix 2 of the National Health Insurance Act Enforcement Decree govern patient shares.
The ordinary dental-clinic share of 30% does not resolve all age-related fixed or tiered payments, Medical Aid, special coverage, provider and visit-specific conditions.
For age-65-plus outpatient care in particular, use the actual patient-payment total confirmed by the provider.
Rounding to the nearest won in the optional formula is a budget approximation; it does not reproduce visit-level truncation or fixed/tiered billing thresholds.
Define crown, retreatment and additional surgery scope
Crown and post/core
Zirconia, gold, PFM and other material selections record the quote and do not automatically change prices.
The general non-covered rule for natural-tooth crowns differs from the specified NHI exceptions for older patients’ dentures and implants.
Do not transfer implant coverage rules to a natural-tooth crown.
Enter post/core covered patient payments and non-covered charges according to the quote; the tool does not determine whether the work is needed.
Root canal retreatment
Selecting retreatment enables additional covered patient payments and non-covered costs outside the base quote.
If existing filling removal or another procedure is already included, leave its extra cost at zero.
Switching to initial treatment excludes retained retreatment inputs from the total.
Apical or other additional surgery
The surgery checkbox creates a budget scenario, not a probability estimate.
Confirmed surgery patient payments and non-covered fees are added only when selected.
When surgery is uncertain, compare the scenario with the checkbox off and on, then discuss the extra cash requirement with your dentist.
Avoid missing or duplicate implant-package charges
The comparison path includes extraction, implant placement with abutment and final restoration, extra bone grafting and other charges.
When the implant package already contains the final restoration, do not add another crown amount.
When covered and non-covered components coexist, do not enter the same service in both columns.
- The covered implant field takes the actual patient share after NHI coverage
- Leave extra bone grafting at zero if it is included in the package
- Check for separate diagnostics, temporary teeth and additional procedures
- Compare preservation and extraction/restoration for the same single tooth
Confirm eligibility and recognized treatment scope with the provider and NHIS.
The calculator does not decide implant coverage or private dental-insurance payouts from age or policy membership.
For several teeth, ask for separate quotes because allocation of shared fees may differ.
Step-by-step use and result interpretation
- Obtain dentist-provided possible treatment plans for the same tooth, including itemized scope
- Record position, confirmed canals and initial treatment or retreatment; enter the actual patient quote
- Add preservation crown/core extras and the comparison extraction, implant and graft costs
- Confirm each full quote; zero means included or not applicable after checking
- Enter assumed durations and annual care costs, then compare totals and annualized amounts
- Print the comparison and check canals, extras and visit-level payments against the treatment plan
A path’s total and comparison remain pending until its quote is confirmed.
A duration of zero means unknown, so a confirmed initial total can appear while annualized cost remains pending.
A dash means missing calculation conditions, not free treatment.
Annualized cost and the equal-cost preservation duration
Annualized cost = initial total ÷ assumed duration + annual care
Preservation break-even years = preservation initial total ÷ (implant annualized cost − preservation annual care)
Annualization spreads one initial expense over a user-selected period.
It is not a clinical lifespan, warranty, replacement recommendation or actual yearly bill.
A longer entered duration can lower the annualized figure, so review initial totals and assumptions together.
The break-even duration is the mathematical point at which the two annualized costs are equal.
A zero or negative denominator has no positive break-even threshold; missing quotes or an unknown implant duration leave the calculation pending.
With zero initial preservation cost, care costs can make preservation equal or cheaper at every positive duration; these cases are shown separately instead of claiming a zero-year break-even point.
This is not a lifecycle cash-flow model connecting future remakes or a switch from preservation to extraction after different durations.
Future treatment changes, inflation, discounting, private-insurance benefits and tax credits are not applied automatically.
Worked fictional example: retreatment through the crown
These figures illustrate arithmetic; they are not national average prices or clinical durations.
With 3 canals, KRW 70,000 in full-course covered fees per canal, KRW 90,000 shared fees and a confirmed 30% share, full covered fees total KRW 300,000 and the base patient payment is KRW 90,000.
Add retreatment extras of KRW 30,000 covered patient payment and KRW 20,000 non-covered charges, a KRW 100,000 non-covered core and a KRW 500,000 crown.
Fictional preservation and extraction/implant quote comparison in KRW| Item | Preservation | Extraction/implant |
|---|
| Covered patient share (KRW) | 120,000 | 20,000 |
| Non-covered (KRW) | 620,000 | 1,500,000 |
| Initial total (KRW) | 740,000 | 1,520,000 |
| Assumed duration (years) | 10 | 10 |
| Annual care (KRW/year) | 20,000 | 30,000 |
| Annualized cost (KRW/year) | 94,000 | 182,000 |
The implant path uses a KRW 20,000 covered extraction patient share, a KRW 1,200,000 non-covered implant package and KRW 300,000 bone grafting.
The initial difference is KRW 780,000 and the annual difference is KRW 88,000; preservation breaks even at 740,000 ÷ 162,000, approximately 4.57 years.
Selecting additional surgery with a KRW 50,000 covered patient share and KRW 100,000 non-covered charge changes preservation’s total to KRW 890,000.
A lower modeled cost is not a treatment recommendation.
Three practical consultation scenarios
Organizing a parent’s multiple appointment bills
Do not use the first payment as the full course cost.
Request the expected patient total over all visits, including extra examinations and the final restoration.
Use the actual-payment mode when older-patient payment rules apply.
Possible surgery during retreatment
Print or save separate comparisons with and without surgery.
The extra cash requirement is shown directly instead of inventing a probability to average the scenarios.
The need and timing for surgery remain clinical consultation matters.
Lower initial cost but different ongoing care
A lower initial bill may lead to a different annual comparison when care costs or durations change.
First compare the same duration, then examine alternative assumptions discussed with the dentist.
This tests cost assumptions; it is not a quality ranking.
Frequently asked questions
Is all root canal treatment covered by NHI?
Separate covered root canal payments from non-covered items such as a crown.
The tool does not adjudicate coverage of each procedure, so use the provider’s itemized classification.
How many canals should I enter for a molar?
Position alone does not determine the count.
Enter the count confirmed after examination, or leave zero and use the total patient-payment quote.
Does retreatment automatically cost more in the calculator?
No universal multiplier is used.
Only entered extras outside the base quote are added when retreatment is selected; leave already-included charges at zero.
Are post and core costs always non-covered?
Split them into covered patient payments and non-covered charges according to the quote.
Your dentist determines whether those materials or procedures are needed.
Can an age-65-plus patient simply multiply by 30%?
Visit-level fixed or tiered payments and eligibility conditions can differ.
Use the actual patient total confirmed by the provider in the default mode.
Is ten years a guaranteed root canal or implant lifespan?
No.
The example’s ten years is a user assumption for arithmetic, not a guaranteed lifespan or a recommended replacement date.
Are blank prices compared as free treatment?
A path’s total and comparison remain pending until its quote is confirmed.
Check that zero fields mean included or not applicable before confirming.
Can a large difference determine extraction or preservation?
Do not decide treatment from cost alone.
Discuss tooth condition, possible treatment and expected progress with your dentist, using this comparison to check the budget.
