If you're enrolled in Korea's national insurance — as most residents are — you're entitled to more free and low-cost preventive dental care than you might realise. Here's how checkups work, what the national screening covers for your teeth, and how to use it — in English.
Prevention is the cheapest dentistry there is — and if you're enrolled in Korea's National Health Insurance (NHIS), a lot of it is already free or heavily subsidised. Many foreign residents don't realise what they're entitled to. Here's how it works, in English.
Korea's national health screening (건강검진)
NHIS offers enrolled adults a general health screening, and foreign residents on NHIS are included. For adults this screening includes an oral exam (구강검진) — a dentist checks for decay, gum disease, and other problems.
- Whether it's your year is based on your birth year, and it usually comes around every two years. NHIS sends a notice; you can also check in the My NHIS portal or app.
- The screening itself is free as part of the program — just bring your ARC (Alien Registration Card).
- It's a screening, not treatment: it finds problems, and any treatment is billed separately (some covered by NHIS, some private).
Checkups and cleaning you can get any time
You don't have to wait for the screening year. Two things are worth knowing:
- NHIS covers one scaling (professional cleaning) per year, with a small share of the cost — an easy, low-cost habit that prevents gum disease.
- A routine checkup any time is inexpensive and catches a cavity or early gum disease while treatment is still simple and cheap.
For children
NHIS also provides infant and toddler oral checkups (영유아 구강검진) at set ages, and covers preventive care like sealants and tooth-coloured fillings for children. There's more in our guide to children's dentistry.
What a checkup finds — and what happens next
| Finding | Typical next step |
|---|---|
| A cavity | A filling (or a crown/root canal if it's deep) |
| Gum disease | Scaling and gum treatment |
| A worn, cracked, or sensitive tooth | Depends on the cause — the dentist explains |
Your dentist tells you what NHIS covers and what's private, with a written estimate before any treatment starts.
How to use it as a foreigner
- Check whether it's your screening year — the NHIS notice or the My NHIS app.
- Book at a participating clinic and bring your ARC.
- For an everyday checkup or your yearly scaling, just book an appointment — no notice needed.

Frequently asked questions
Do foreign residents get Korea's national dental screening?
Yes, if you're enrolled in NHIS. The national general health screening includes an oral exam for adults, and foreign residents on NHIS are included. Whether it's your year depends on your birth year — check the NHIS notice or the My NHIS app, and bring your ARC.
How often is the national health screening?
For most adults it comes around every two years, based on your birth year. NHIS notifies you when it's your turn; you can also check your eligibility in the My NHIS portal or app.
Is a dental cleaning (scaling) free in Korea?
Not free, but low-cost: NHIS covers one scaling per year, so you pay only a small share. It's one of the easiest ways to prevent gum disease, so it's worth using every year.
What if the screening finds a problem?
The screening is an exam — it identifies issues but doesn't treat them. Treatment is separate: NHIS covers essentials like fillings, extractions, root canal, and gum treatment (you pay a share), while cosmetic work is private. You'll get a written estimate first.
Can I get it explained in English?
Yes. At Seoul Lab Dental we explain your screening results, what NHIS covers, and any costs in English before treatment begins.
