My gum treatment finished quickly without anesthesia. Was it done properly?

If the periodontal pockets are shallow and there is little tartar below the gums, treatment can be short and done without anesthesia. If the pockets are deep and inflammation is severe, it takes longer and anesthesia is used. Treatment time depends on the depth and extent found in the examination, so time alone is not a good measure of whether it was appropriate.

My gums receded more after gum treatment. Did something go wrong?

Often, gums that were swollen from inflammation settle after treatment and reveal their original position. The procedure does not cut away the gums, but the spaces between teeth may look larger or there may be temporary sensitivity. If the change keeps progressing, it should be reevaluated.

It does not hurt, but I was told I need gum treatment. Why?

Periodontitis often progresses without pain, so symptoms alone cannot tell you whether treatment is needed. Periodontal pocket depth measurements and X-ray results are the basis for the decision, so you can ask for an explanation based on those numbers.

Is it okay for a dental hygienist to do my gum treatment?

Under Korean law, some procedures such as tartar removal fall within a dental hygienist's scope of work, while diagnosis and treatment planning are the dentist's responsibility. If you want to know who will perform it, you can ask before the procedure.

Is gum treatment covered by Korean health insurance?

Root planing and periodontal curettage for treating periodontal disease are covered items under National Health Insurance. When it is split into sessions, there is a charge for each session, and some procedures such as bone regeneration surgery may be billed as non-covered (not paid by National Health Insurance), so checking what is covered helps.

My teeth are still sensitive and sore after treatment. Did it fail?

When tartar is removed, the root surface can be exposed and cause temporary sensitivity. However, if pain lasts a long time or keeps getting worse, another cause needs to be checked, so you should return to the dentist.

Gum Treatment (Root Planing and Periodontal Curettage): Procedure, Why It Is Split Into Sessions, Pain, and Changes Afterward

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 Gums and periodontal health, Gum treatment formed a question cluster of about 2,800 comments. Gum treatment removes tartar and inflamed tissue below the gum line, unlike scaling. This guide covers why it is split into sessions, anesthesia and pain, and why gums can look lower afterward.

What does gum treatment do?

Gum treatment (root planing and periodontal curettage) is a procedure that removes tartar and inflamed tissue attached below the gum line, that is, subgingivally [1]. As periodontitis progresses, the groove between the gums and teeth deepens into a periodontal pocket, and tartar builds up on the root surface inside it [1]. Root planing smooths the root surface by removing this tartar and the contaminated surface, and periodontal curettage also removes the inflamed tissue lining the pocket [3]. It is a separate procedure from scaling, which removes tartar above the gum line, with a different target area and purpose, and Korean health insurance also classifies periodontal treatment as a covered item [2].

DentStat analyzed about 2,800 patient comments on gum treatment in YouTube dental content. Questions repeated along three lines: “Why is it split into several sessions?”, “It finished quickly, so was it done properly?”, and “My gums seem to have receded after treatment.” [4].

Why is it done in several sessions by area?

Dividing the mouth into areas rather than treating it all at once is a common approach that considers the extent of anesthesia and the precision of treatment [3]. Subgingival treatment is often done under local anesthesia. Numbing the whole mouth at once makes eating and speaking harder, and treating smaller areas makes it easier to find and remove deep tartar [3]. For this reason it is usually done over several sessions, divided into upper, lower, left, and right, and the number of sessions depends on the extent of inflammation and the depth of the pockets [3].

The comment analysis found many responses suspecting that splitting the treatment was a way to increase costs [4], but this can be checked by getting an explanation of the treatment plan in advance, including the fact that periodontal treatment is a covered item billed per session [2].

Why does it hurt even with anesthesia?

The degree of pain varies widely depending on pocket depth and the state of inflammation [3]. Shallow areas are sometimes treated without anesthesia, while deep areas may still feel pressure or scraping even after anesthesia [3]. Pain and sensitivity can continue for several days after the anesthesia wears off, which is explained as a reaction to the root surface being exposed when tartar is removed [3]. In the comment analysis, fear of pain and anesthesia also appeared as a main reason for putting off gum treatment [4]. If the pain does not decrease over time and gets worse, you should return to the dentist for reevaluation [3].

Is it a problem if my gums look lower after treatment?

Usually, gums that were swollen from inflammation settle and reveal their original position; the procedure did not cut away the gums [3]. When the swelling goes down, teeth can look longer or the spaces between teeth (interdental gaps) can look larger, and the exposed root surface can be temporarily sensitive [3]. In the comment analysis, reactions suspecting a medical error because this change had not been explained beforehand came up repeatedly [4]. The way to confirm is to be told about expected changes before treatment, and to get reevaluated if recession continues after treatment [3].

Common myths and facts

Myth	Fact
Gum treatment is surgery that cuts the gums	The basic treatment is a nonsurgical procedure that scrapes off tartar below the gums; periodontal surgery with incisions is considered in advanced cases [3]
If you get scaling regularly, you do not need gum treatment	Scaling deals with the area above the gums and gum treatment with the area below; they are separate procedures that do not replace each other [1]
Gum treatment causes gum recession	The lowered look is often the result of inflammatory swelling going down [3]
The more often, the better	Whether it is needed and how often depends on examination results (such as pocket depth); discuss it with a dentist [3]
