I went in only for scaling and was recommended an implant or a crown. Is that overtreatment?

A recommendation does not by itself mean overtreatment; it depends on what was recommended. Scaling and gum treatment are covered by National Health Insurance, so their cost structure is public. On the other hand, if you are recommended an expensive non-covered procedure right at your first visit, it helps to have the diagnostic basis explained and to check another clinic's opinion as well.

If different clinics give different diagnoses, which one should I trust?

For expensive non-covered treatments where diagnoses differ, or hard-to-reverse procedures such as extraction, you can get a second opinion from another clinic before deciding. Diagnosis and the treatment plan are set by the dentist, and the way to check is to ask for an explanation based on the examination results.

Does a loose tooth always have to be pulled and replaced with an implant?

If the tooth is loose because of periodontitis, saving it with periodontal treatment may be considered. Whether to extract or save it depends on examination results such as the degree of jawbone loss, so you can check the basis and, if needed, get another clinic's opinion.

Worried About Overtreatment at a Scaling Visit: Covered vs. Non-Covered Recommendations, X-Rays, and Second Opinions

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, Distrust of Overtreatment formed a question cluster of about 2,400 comments. A recommendation made during scaling is not overtreatment by itself. This guide covers how to judge extra treatment, why X-rays are taken, the covered vs. non-covered distinction, and how to use a second opinion.

Key facts

Recommendations for covered treatment	Scaling and gum treatment are covered by National Health Insurance: the cost structure is public ^[2]
X-rays	Tartar shows poorly, but X-rays are used to diagnose jawbone, below-the-gumline condition, and cavities ^[1]
Second opinion	For expensive non-covered or hard-to-reverse procedures, you can consult another clinic before deciding ^[1]
Early decay	Monitored or treated depending on whether it is progressing: judged on examination findings ^[1]
Volume of patient questions	About 2,400 comments on overtreatment and choosing a clinic ^[4]

Is it overtreatment if other treatment is recommended when I go in for scaling?

It depends on what is recommended, and a recommendation does not by itself mean overtreatment [1]. If tartar below the gumline or cavities are found during scaling, periodontal treatment or cavity treatment may be suggested as well [1]. Tartar removal and gum treatment (root planing and periodontal curettage) are covered by National Health Insurance (Korea’s public health insurance), so recommendations for these treatments involve care with a public cost structure [2]. On the other hand, if you are recommended an expensive non-covered (not paid by Korea’s National Health Insurance) procedure such as a crown or implant right at your first visit, it helps to have the diagnostic basis explained and to check another clinic’s opinion as well [3].

When DentStat analyzed about 2,400 patient comments on YouTube dental content about overtreatment, recurring responses included “I compared quotes from several clinics” and “I was worried because they recommended expensive treatment without explanation” [4].

Why are X-rays needed for scaling?

X-rays are an examination to check things the eye cannot see, such as the jawbone, tartar below the gumline, and cavities, all at once [1]. Tartar itself has low density and does not show clearly on X-rays, but jawbone loss from periodontitis or cavities between teeth can sometimes be seen [1]. Radiation exposure is usually kept to the minimum needed for the diagnostic purpose, and whether and how much to image depends on symptoms and the condition of the mouth [1]. If extensive X-rays are repeated every time for simple scaling, the way to check is to ask why they are needed [3].

What can you check before deciding on treatment?

Before deciding on treatment, you can check who made the diagnosis, whether the treatment is covered or non-covered, and another clinic’s opinion [1]. Diagnosis and the treatment plan are set by the dentist, and they are separate from explanations of cost and appointments [3]. Knowing whether a recommended treatment is covered or non-covered by National Health Insurance helps you understand the cost structure [2]. For expensive non-covered treatment or hard-to-reverse procedures such as extraction, getting another clinic’s opinion (a second opinion) before deciding is a step patients can use [1]. Even with the same examination results, judgments about when and how to treat can differ between clinics, so getting an additional consultation when opinions differ is a normal option for patients [1].

Should an early cavity be treated right away?

An early cavity that has stopped progressing is sometimes monitored instead of being drilled right away [1]. Depending on how far it has progressed, decay (a cavity) may be watched at regular checkups or may need treatment if it is progressing [1]. Surface staining or arrested decay is judged differently from decay that is progressing inward, so whether to treat immediately or monitor is something to discuss with the dentist based on the examination results [1]. A loose tooth, too, may be considered for saving with periodontal treatment if the cause is periodontitis [3].

Common misconceptions and facts

Misconception	Fact
Recommending scaling often is just sales	It is covered once a year for adults 19 and older and has an evidence base for preventing periodontal disease [2]
If the recommended treatment is covered by insurance, there is nothing to worry about	Even for covered treatment, the need is confirmed by examination findings [1]
A loose tooth must always be pulled and replaced with an implant	It can sometimes be saved with periodontal treatment, so it is worth checking the clinical opinion [3]
A visible cavity must be drilled and filled immediately	Early decay that has stopped progressing is sometimes monitored [1]

On the other hand, if you are recommended an expensive non-covered procedure right at your first visit, it helps to have the diagnostic basis explained and to check another clinic's opinion as well.
Why do they take X-rays during scaling?: It is an examination to check the jawbone, tartar below the gumline, and cavities together. Tartar itself has low density and does not show clearly on X-rays, but jawbone loss from periodontitis or cavities between teeth can sometimes be seen. You can ask for an explanation of why the X-ray is needed.
