Teeth Cleaning in Korea: One Insured Scaling a Year, About ₩18,000

Last updated: 22 Oct 2026. As of October 2026: fees from the 2026 dental fee schedule, rules from the National Health Insurance Service (NHIS) page on scaling, read that day. ₩1,326 = $1 (open.er-api.com, 22 October 2026). A guide, not dental advice; sources at the end.

Teeth cleaning in Korea is one of the cheapest routine appointments in the developed world, and for anyone enrolled in Korea's national health insurance it is cheaper still: one scaling (스케일링, officially 치석제거) a year is covered for every insured adult aged 19 and over. In 2026 the fee for a full-mouth cleaning is ₩43,950 (about $33). With the first-visit consultation added, the bill at a neighbourhood dental clinic is about ₩60,800, and the patient pays 30% of it: about ₩18,200 (≈ $14).

The rule most foreigners have never heard is the calendar. The allowance runs from 1 January to 31 December, it is one per year, and an unused year does not carry over. If you are insured in Korea and have not had a cleaning in 2026, you have until 31 December to use this year's.

Quick Guide: teeth cleaning in Korea, October 2026

The cleaning is the same whether you are insured or not; only the payer changes. So two questions matter: are you insured, and have you already used this year's cleaning?

Where ₩18,000 comes from: the 2026 fee

Korean clinics do not set the price of insured treatment. Every covered procedure has a points value in the national fee schedule, and each year NHIS and the dental association agree on what a point is worth. For 2026, NHIS's own disclosure page puts the dental conversion factor at ₩101.1 a point, up 2% from ₩99.1 in 2025.

The Korean Dental Association's newspaper published the 2026 dental figures from the Health Insurance Review and Assessment Service (HIRA) fee file on 7 January 2026. Scaling has two lines:

The consultation lines use 166.59 and 110.46 points, figures per a third-party calculator (Glasswallet), multiplied by ₩101.1; we could not open the official points table. Calculators round slightly differently, so expect differences of ₩10–30: Glasswallet, for instance, gives the full-mouth cleaning as 434.71 points = ₩43,940. None of that moves the answer. The "about ₩18,000" in the title is 30% of a fixed government fee plus a consultation, not a clinic advert. Your receipt can be higher if the dentist adds another covered item, most often an X-ray; ask first if you only came for the cleaning.

Clinic, dental hospital or university hospital: what you pay

The fee is national, but the share you pay depends on the kind of institution. NHIS's outpatient co-payment table sets it like this:

The hospital rows apply each share to the clinic fee; hospitals bill slightly more (the 2026 implant fee is about 4% higher at a dental hospital), and a university dental hospital's share depends on how it is registered. For a routine cleaning, a 치과의원 is the cheapest place and where most Koreans go.

The 1 January reset, and why clinics are busy in December

NHIS counts the cleaning from 1 January to 31 December. Until the end of 2017 the year ran from 1 July to 30 June, which is why older English guides say it resets in summer. Two things follow:

• The year is per person, not per clinic. A cleaning at another dentist in March shows up on the NHIS record when a new dentist checks in November.
• Late December and early January are different years, so a cleaning on 28 December and another on 5 January are both covered.

Most people do not use it at all. Newsis, citing HIRA data on 1 November 2025, put scaling patients at about 15.25 million in 2022 (up from 13.43 million in 2020) and said about 70% of adults do not use the insured cleaning. Korean news runs a "get your scaling before December ends" story every year, so clinics in residential areas fill up in the last two weeks of December. Book a week or two ahead.

Which foreigners get the insured price

This depends on enrolment, not nationality. The cleaning is covered for anyone enrolled in national health insurance, Korean or foreign, and for their registered dependants. Our guide to health insurance for foreigners in Korea covers enrolment in detail. In short:

• Employees at a Korean workplace are insured from their first day of work.
• D-2 university students are enrolled from their alien registration.
• Most other long-stay visas are enrolled automatically after six months in Korea.
• Tourists and short-stay visitors are not insured, and neither is a new arrival still inside the six-month wait.

One catch: if your premiums are more than a month overdue, NHIS can stop covering your treatment (a few visa types get three months), and the clinic will see that. Clear any arrears before you book.

Bring your alien registration card (외국인등록증), a passport or the NHIS mobile health card. Since 20 May 2024 clinics must check a patient's identity, with exceptions such as a patient already checked at the same clinic within the past six months, according to Korean press reports at the launch (Asia Economy, Dailypharm). If you forget your ID and are billed as uninsured, the same reports say you can bring the ID and receipt back within 14 days to have the difference refunded.

Not insured: what tourists and new arrivals pay

If you are not enrolled, the same cleaning is non-covered, and the clinic charges its own price. There is no national tariff for an uninsured patient. Reference points:

• Clinic price lists checked for our implant guide commonly show ₩50,000–60,000 (≈ $38–45). That matches the full official fee for a first visit, about ₩60,800.
• Korean consumer cost guides (Banksalad, Glasswallet) give a wider ₩50,000–100,000 (≈ $38–75); the top of that range usually includes extras such as polishing or air-flow stain removal.

Still a fraction of a US cleaning, but ask the clinic first: "보험 없이 스케일링 얼마예요?" (How much is scaling without insurance?)

How to check whether you have used this year's cleaning

You do not have to keep track. The clinic checks for you: NHIS's instructions to dentists are to look up the patient's remaining count on the NHIS provider portal before the cleaning. If you still have one, they register the date and bill it as covered; if not, it is billed as non-covered. If the clinic does not say which, ask before it starts.

To check yourself:

• On the NHIS website, search the service finder for 치석제거 to reach the scaling record lookup (치석제거 진료정보 조회). You need Korean certificate or simple-authentication login.
• In the NHIS mobile app (listed as The건강보험), menu names change between versions, so search 치석제거 inside the app.
• By phone: NHIS's English line is 033-811-2000 (the general call centre is 1577-1000).

How to book a teeth cleaning in Seoul as a foreigner

There are dental clinics on almost every block of every Korean city; you do not need a "foreigner clinic" for a cleaning.

1. Find a clinic. Search 치과 on Naver Map or Kakao Map. A sign ending in 치과의원 is a clinic (30% share); 치과병원 is a dental hospital (40%). Many clinics take bookings in the map app (look for 예약); otherwise phone.
2. Say what you want. "건강보험 스케일링 예약하고 싶어요" (I'd like to book an insured scaling). If you are not insured: "보험이 없어요" (I don't have insurance).
3. Bring your ID. Alien registration card if you are insured; a passport if you are not.
4. Expect a short appointment, usually well under an hour, often done by a dental hygienist (치과위생사) with the dentist checking afterwards.
5. If you need help with Korean, the Korea Tourism Organization's 1330 Korea Travel Helpline offers English and three-way phone interpretation. The government's Medical Korea site (medicalkorea.or.kr, run by the Korea Health Industry Development Institute) lists hospitals and clinics registered to treat foreign patients. We have not tested any individual clinic, so we name none here.

Some clinics mention English-speaking staff in their map listing, but a cleaning needs little explaining: the phrases above and an ID card are enough.

What the insured cleaning does not cover

NHIS lists the cases where scaling is non-covered even if you have not used this year's:

• removing bad breath (구취 제거) or stains and discolouration (치아 착색물질 제거);
• scaling done to prepare for braces (교정) or for crowns and bridges (보철);
• regular "maintenance" cleanings for general oral health, beyond the yearly one.

The yearly benefit is for a cleaning that ends the treatment: the tartar comes off and you go home. If the dentist finds gum disease that needs further treatment, scaling is billed as part of that treatment under different rules (the ₩9,870 per-third line in the fee table). Ask the clinic how it will be billed before you start.

The rest of Korea's dental coverage is narrow and mostly age-based: tooth-coloured resin fillings for decay in children's permanent teeth up to age 12, sealants on the back teeth up to 18, and implants and dentures from 65. For adults, most restorative work is non-covered and priced by the clinic; our dental implant cost guide shows how to look up what each clinic charges.

The only other product worth naming: tartar starts as plaque between the teeth, where a brush does not reach, which is why the water flosser linked at the top is the daily tool dentists most often suggest (Korea runs on 220 V, so buy for the country where you will use it).

The honest part

• If you are a tourist, do not plan a trip around a cleaning. The ₩18,000 price is not available to you, and Korea's dental savings are in implants and crowns, not cleanings.
• One cleaning a year is the insured minimum, not a medical recommendation. If your dentist recommends more, the extra ones are non-covered, and the clinic should tell you the price first.
• The insured fee is identical everywhere; what differs is care and sales pressure. A clinic that pushes whitening or a package during a routine scaling is a reason to go elsewhere next year.

FAQ

Q: How much is teeth cleaning in Korea?

A: With national health insurance, a full-mouth scaling at a neighbourhood dental clinic costs the patient about ₩18,200 (≈ $14) on a first visit and about ₩16,500 (≈ $12) as a returning patient in 2026: 30% of the ₩43,950 scaling fee plus a consultation. Without insurance, clinics set their own price, commonly ₩50,000–60,000 (≈ $38–45).

Q: How often does Korean health insurance cover scaling, and when does it reset?

A: Once a year for adults aged 19 and over, counted from 1 January to 31 December. A second cleaning in the same year is non-covered, and an unused year does not carry over.

Q: Can foreigners get insured scaling in Korea?

A: Yes, if they are enrolled in national health insurance: employees from their first day of work, D-2 university students from registration, and most other long-stay residents after six months. Tourists are not insured and pay the clinic's price.

Q: How do I know if I have already used my scaling this year?

A: The clinic checks the NHIS record before the cleaning and tells you whether it is covered. You can also search 치석제거 on the NHIS website or app, or call NHIS's English line on 033-811-2000.
