Is scaling covered by National Health Insurance for people under 19?

National Health Insurance coverage for tartar removal is set at once a year for people 19 and older, so those under 19 are not covered. The procedure itself is available, but it is provided as non-covered (paid out of pocket). Eligibility is based on international age (full years since birth), so check whether you turn 19 in that year.

Is there a set interval for scaling?

Tartar builds up at different rates in different people, so there is no single fixed interval. Smoking, wearing orthodontic appliances, and a history of periodontal disease are known factors that make tartar build up more often. The once-a-year insurance rule is only a cost rule and does not necessarily match the right care interval for an individual.

If I brush thoroughly, can I skip scaling?

Tartar that has already hardened cannot be removed by brushing, so scaling is needed. Tartar in places the toothbrush does not reach, or below the gumline, cannot be seen, so whether you have tartar is something to confirm at a checkup. The purpose of home care is not to remove tartar but to reduce plaque, the stage before it becomes tartar.

I went for the first time in years and was told there was almost no tartar to remove. Is that possible?

Because of individual differences in saliva and the oral environment, tartar builds up slowly in some people, so there may be little to remove even after a long gap. Others build up a lot in a short time, so checking the condition of your mouth, rather than the interval, is the basis for the decision.

Scaling Interval, Cost, and National Health Insurance: The Once-a-Year Rule From Age 19 and How Often to Go

Published August 3, 2026 Updated August 3, 2026 Based on official HIRA and Ministry of Health and Welfare data and public sources

In the analysis of patient comments about Scaling, Interval, Cost, and Insurance formed a question cluster of about 2,100 comments. Korea's National Health Insurance covers one scaling a year from age 19. This guide covers non-covered cases (minors, a second visit in a year), why there is no fixed interval, and why brushing cannot replace it.

Key facts

Insurance coverage	Tartar removal covered once a year for adults 19 and older ^[2]
How it is counted	Counted by calendar year (resets January 1): covered again when the year changes ^[2]
Not covered	Under 19, or a second scaling in the same year, is not covered (available as non-covered) ^[2]
Factors affecting interval	Smoking, orthodontic appliances, and a history of periodontal disease call for more frequent care ^[1]
Volume of patient questions	About 2,100 comments on interval, cost, and insurance ^[3]

Who is covered for scaling by National Health Insurance, and how many times?

For adults 19 and older, tartar removal (scaling) is covered by National Health Insurance (Korea’s public health insurance) once a year [2]. The count is calculated by calendar year and resets on January 1 each year, so you can get it as a covered service again when the year changes [2]. Periodontal treatment that removes tartar below the gumline (root planing and periodontal curettage) is classified as a covered item separate from this once-a-year rule [2].

When DentStat analyzed about 2,100 patient comments on YouTube dental content about scaling interval, cost, and insurance, three recurring questions appeared: “is it really once a year?”, “what if I’m not 19 yet?”, and “I already had it but want another one” [3]. Along with these, skepticism about whether scaling is needed at all (“I went after several years and they said there was nothing to remove,” “if I brush well, do I even need it?”) was observed as another thread [3].

What happens if you are under 19 or get a second scaling in the same year?

Because National Health Insurance coverage is set at once a year for people 19 and older, scaling for those under 19 or a second scaling in the same year falls outside coverage [2]. Minors can also develop tartar, so care is needed in the teenage years too; the procedure is available, but in this case it is provided as non-covered (not paid by Korea’s National Health Insurance) rather than covered [2]. Coverage begins in the year a person turns 19 [2]. Even if covered scaling has already been used that year, periodontal treatment for periodontal disease, when needed, is provided as a separate covered item [2].

How often should you get scaling?

There is no single fixed interval; it depends on how fast tartar builds up in each person [1]. Saliva composition, oral hygiene habits, and smoking affect the rate of tartar buildup, and smokers, people with orthodontic appliances, and people with a history of periodontal disease are known to build up tartar more often [1]. The once-a-year insurance rule is only a cost rule and does not necessarily match the right care interval for an individual [2]. The interval that suits you should be discussed with a dentist who has checked your mouth [1].

If you brush well, can you skip scaling?

Even with thorough brushing, tartar that has already hardened is not removed, so scaling is needed [1]. Tartar is calcified plaque (the bacterial film in the mouth), and tartar that forms in places the toothbrush does not reach or below the gumline cannot be seen [1]. For this reason, it is hard to tell on your own whether you have tartar, and it is confirmed at a checkup [1]. Floss and interdental brushes are supplementary tools that reduce plaque between teeth where the toothbrush does not reach, but they cannot remove tartar that has already calcified [1]. The comment analysis also observed skepticism about the need for scaling, such as “if I brush well, don’t I not need scaling?”, as one thread [3].

Common misconceptions and facts

Misconception	Fact
Insurance covers it only once a year, so you cannot get it more often	An additional scaling in the same year is available as non-covered, and periodontal treatment is a separate covered item [2]
I don’t build up tartar easily, so I never need it	Tartar below the gumline cannot be seen and is confirmed at a checkup [1]
The more often, the better	The right interval depends on the condition of your mouth and should be discussed with a dentist [1]
Minors cannot get scaling	The procedure is available, but people under 19 are not covered by National Health Insurance [2]

Frequently asked questions

Is scaling covered by National Health Insurance for people under 19?: National Health Insurance coverage for tartar removal is set at once a year for people 19 and older, so those under 19 are not covered. The procedure itself is available, but it is provided as non-covered (paid out of pocket). Eligibility is based on international age (full years since birth), so check whether you turn 19 in that year.
I already had scaling this year, but I want another one.: A second scaling in the same year is not covered and is provided as non-covered. However, periodontal treatment that removes tartar below the gumline (root planing and periodontal curettage) is a covered item separate from the once-a-year scaling rule, so treatment for periodontal disease, when needed, is provided under separate criteria.
Is there a set interval for scaling?: Tartar builds up at different rates in different people, so there is no single fixed interval. Smoking, wearing orthodontic appliances, and a history of periodontal disease are known factors that make tartar build up more often.
