What do patients ask about most?
Analysis of 15,200 patient question comments on YouTube content about Scaling (collected June 28, 2026).
What is dental scaling?
Scaling (tartar removal) is a procedure that uses ultrasonic instruments and other tools to remove tartar, plaque, and stains attached to the tooth surface [1]. Tartar is plaque (the bacterial film in the mouth) that has hardened and calcified, and once it forms, brushing cannot remove it [1]. Because plaque and tartar are major causes of gum inflammation (gingivitis) and periodontitis, scaling is classified as a basic procedure to prevent periodontal disease and stop it from progressing [1].
When DentStat analyzed 15,200 patient comments about scaling on YouTube dental content (4,518 of them questions), the most common topics were telling it apart from gum treatment (927), interval, cost, and insurance (715), home oral care (629), and pain and sensitivity (596), in that order [4]. This guide follows that order and summarizes facts confirmed by public sources.
How does National Health Insurance cover it?
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, 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 a covered item separate from the once-a-year scaling rule [2]. Even if you have already used your covered scaling for the year, treatment for periodontal disease, when needed, is provided under separate criteria [2].
What is the difference between scaling and gum treatment?
Scaling removes tartar visible above the gumline (supragingival), while root planing and periodontal curettage, often called gum treatment, are periodontal treatments that remove tartar and inflamed tissue from the root surfaces below the gumline (subgingival) [1]. When periodontitis has progressed, scaling alone does not remove the tartar below the gumline, so staged periodontal treatment sometimes follows [1].
In the patient comment analysis, confusion along the lines of “doesn’t scaling clean all the way under the gums too?” was the largest theme (927 comments) [4]. The key distinction is that the two are separate treatments with different target areas and different insurance criteria [2].
Does scaling make teeth sensitive or open gaps?
Temporary sensitivity after scaling is a common reaction. As tooth surfaces and root areas that were covered by tartar become exposed, they can become sensitive to temperature, and this usually eases within 1 to 2 weeks [1]. If sensitivity lasts a long time or gets worse, there may be another cause, and it should be discussed with a dentist.
When people feel that gaps have opened between their teeth after the procedure, it is often the space the tartar used to fill, or gum recession that had already occurred becoming visible as swollen gums settle down [1]. Lost jawbone does not grow back on its own, so the goal of periodontal care is to stop progression, not to restore what was lost [1]. Questions suspecting side effects or tooth damage numbered 124 in the comment analysis [4].
How often should you get it?
The rate of tartar buildup varies a lot between individuals, depending on saliva composition, oral hygiene habits, smoking, and other factors [1]. Smokers, people wearing orthodontic appliances, and people with a history of periodontal disease are known to need more frequent plaque and tartar control, and the right interval for each person should be discussed with a dentist who has checked their mouth [1].
Questions about interval, cost, and insurance were the second most common theme in the comment analysis, at 715 [4]. The insurance coverage rule (once a year) is only a cost rule and does not necessarily match the right care interval for an individual [2].
Can you remove tartar at home?
Tartar that has already hardened cannot be removed by brushing, flossing, or mouthwash; it requires scaling with dental instruments [1]. The purpose of home care is not to remove tartar but to reduce plaque, the stage before it becomes tartar [1].
Floss and interdental brushes are supplementary tools that remove plaque between teeth where toothbrush bristles do not reach [1]. Questions about home oral care were the third theme in the comment analysis, at 629, showing demand for information on how to use these tools correctly [4].
Dental clinics nationwide (number and location of board-certified specialists in Periodontics, and more) can be checked on DentStat’s regional pages, based on public data from the Health Insurance Review & Assessment Service (HIRA) [3].

Frequently asked questions
- How many times a year does National Health Insurance cover scaling?
- For adults 19 and older, tartar removal (scaling) is covered by National Health Insurance once a year. The count is calculated by calendar year, so coverage becomes available again when the year changes. Periodontal treatment that removes tartar below the gumline is classified as a separate covered item.
- What is the difference between scaling and gum treatment?
- Scaling removes tartar and plaque visible above the gumline (supragingival), while gum treatment (root planing and periodontal curettage) is a separate periodontal treatment that removes tartar from the root surfaces below the gumline (subgingival). Getting scaling does not also remove tartar below the gumline.
- My teeth are sensitive after scaling. Is that normal?
- Tooth surfaces that were covered by tartar become exposed, which can cause temporary sensitivity. It usually eases within 1 to 2 weeks. If sensitivity lasts a long time or keeps getting worse, there may be another cause, and it should be discussed with a dentist.
- Does scaling grind down teeth or open up gaps between them?
- Scaling does not grind teeth; it removes tartar attached to the surface. Gaps that appear between teeth afterward are often the space the tartar used to fill, or gum recession that had already occurred becoming visible. If you suspect damage, discuss it with a dentist.
- How often should I get scaling?
- Tartar builds up at different rates in different people, so there is no single interval. Smoking, wearing orthodontic appliances, and a history of periodontal disease are known to affect tartar buildup, and the right interval for you should be discussed with a dentist who has checked your mouth.
- Can I remove tartar at home?
- Tartar is hardened, calcified plaque and cannot be removed by brushing or flossing; it requires scaling with dental instruments. Floss and interdental brushes are tools for managing plaque, the stage before it becomes tartar.
