"I've heard scaling opens up gaps between your teeth — is that true?"
"I hear it's covered by insurance, but how many times a year?"
"My teeth get sensitive after a scaling, and it puts me off..."
So many people looking into scaling in Uijeongbu come in with exactly these worries.
Hello, I'm Dr. Choi Yong-seok, Director of Dr.Beauty Dental Hospital in Uijeongbu.
Today I'd like to go one by one through 6 points about scaling (the gap myth, health insurance, sensitivity, intervals, effects, and regular checkups).
Scaling is the most basic treatment there is, and also one of the most misunderstood, so knowing it properly helps.
Many people take it lightly as "just a cleaning," but it is in fact the most basic form of care for keeping gum disease at bay.
Conversely, putting it off because of a misunderstanding often means missing the very care you should be keeping up.
Just 3 minutes of your time should clear up some of the myths and worries around scaling.
1. Does Scaling Really Open Up Gaps Between Teeth?
"My teeth look gappy since the scaling."
This is a very common misunderstanding.
To give the conclusion first: scaling does not push healthy teeth apart.
When tartar has built up over a long time between the teeth and gums, the gums swell and that tartar fills the space; removing the tartar with a scaling is known to reveal the real space that had been hidden, which makes it look gappy.
In other words, the scaling didn't create the gap — it is closer to the space already created by gum disease becoming visible.
If anything, leaving that tartar in place lets gum disease progress further, and the teeth can genuinely start to loosen.
In the clinic I meet people who say they put off scaling for fear of gaps, and in many cases delaying only costs them more.
If anything, looking gappy also means that a lot of tartar had accumulated.
Because it is the original space showing as the swelling subsides and the gums become healthier, it often becomes less noticeable once the gums settle with time.
✔ Scaling does not push healthy teeth apart
✔ Space that was hidden by tartar is revealed, making it look gappy
✔ Left alone, gum disease can genuinely loosen the teeth
The myth that "scaling opens up gaps" is what actually puts teeth at risk.
2. How Many Scalings a Year Does Health Insurance Cover?
"I hear it's covered, but that there are conditions."
That's right — knowing the conditions lets you make good use of it.
For adults 19 and older, scaling is known to be covered by national health insurance once per year. The coverage criteria and interval may change with policy.
That said, once a year is not always enough depending on the state of your gums, so if tartar builds up easily or gum disease is progressing, you may be advised to have it managed more often.
Additional scaling or gum treatment at that point may carry a separate cost depending on your condition.
Knowing in advance which situations bring additional cost lets you keep up your care without unexpected burdens. Even just keeping up the basic covered scaling is enough as a starting point for gum care.
Alongside regular tartar management, dental clinics generally recommend checkups at 6-month intervals.
The right interval differs from person to person, so it is a good idea to confirm the interval that suits your own gums at a checkup.
Many people ask whether they need to cram it in at the end of the year, but you can have it whenever suits you within the set interval.
What matters is less the timing than the habit of making sure it happens at least once a year.
✔ For adults 19 and older, national health insurance covers it once per year
✔ Depending on gum condition, more frequent care may be needed
✔ Checkups at 6-month intervals are generally recommended
Insurance-covered scaling starts with making sure "once a year" actually happens.
3. Why Do Teeth Feel Sensitive After a Scaling?
"Every time I have a scaling, my teeth are sensitive for a few days."
Many of you will have experienced this.
Sensitivity after a scaling is relatively common, and usually temporary.
Tooth surfaces that had been covered by tartar are exposed and can be briefly reactive, but this is known to improve gradually over the course of a few weeks.
While the sensitivity lasts, it helps to avoid very cold or very hot foods, and a desensitizing toothpaste can be useful.
If the gums have receded considerably and the tooth roots are exposed, however, the sensitivity may last longer.
So if the sensitivity lingers or one particular tooth hurts badly, it is a good idea to check whether there is another cause.
Some people put scaling off saying the sensitivity is too much to bear, but leaving tartar in place is the greater loss for gum health.
If sensitivity worries you, having the aftercare explained beforehand can ease the burden.
✔ Sensitivity after a scaling is common and usually temporary
✔ The exposed tooth surface adjusts and improves over a few weeks
✔ If sensitivity lingers, check whether there is another cause
Sensitivity after a scaling is mostly an adjustment process, not a loss.
If you're planning a scaling or regular checkup in Uijeongbu, you can review the care intervals first on our cavity and scaling guide and Uijeongbu dental checkup page.
Key Takeaways
✔ Point 1: Scaling doesn't push teeth apart — hidden space becomes visible
✔ Point 2: Covered once a year for adults 19 and older — more may be needed depending on condition
✔ Point 3: Sensitivity after a scaling is usually temporary and improves over a few weeks
I hope this helps anyone considering a scaling in Uijeongbu.
Thank you for reading.

Scaling in Uijeongbu: Does It Leave Gaps Between Teeth? 6 Things Including Insurance
This article was written directly by Dr.Beauty Dental Hospital in compliance with Article 56, Paragraph 1 of the Medical Service Act. Individual results may vary, and side effects including sensitivity, gum irritation, and temporary bleeding may occur.
Frequently Asked Questions
Does scaling hurt?
Scaling is mostly carried out without anesthesia, and the pain tends to be limited. That said, if there is severe gum inflammation or a heavy build-up of tartar, the gums may feel sensitive or bleed slightly during or after the procedure. This tends to be felt more the worse the gum inflammation is, which is itself a signal that care was needed. Gum treatment that removes tartar deep beneath the gums sometimes involves local anesthesia as required. Sensitivity to pain varies between individuals, so if you feel uncomfortable during the procedure, saying so lets it be adjusted as the work continues.
Can I have a scaling while pregnant?
Scaling is known to be relatively safe to receive during pregnancy. Hormonal changes during pregnancy make the gums prone to swelling and inflammation (pregnancy gingivitis), so it is in fact a time when care matters more. Dental treatment is known to be relatively safe throughout pregnancy, and the second trimester is often the most comfortable time, with less nausea and discomfort. Radiographs and medication do require caution, however. That is why it is important to let the clinic know that you are pregnant and how many weeks along when you visit. Judgment can differ with individual circumstances, so it is best to manage it in consultation with both your obstetrician and your dentist.
Does scaling shave down or damage the teeth?
Scaling does not shave down the tooth itself; it detaches tartar and staining that have adhered to the tooth. Because hard tartar is removed by the vibration of an ultrasonic instrument, the degree of damage to healthy tooth surface (enamel) is known not to be large. Given the nature of the procedure, fine roughness can remain on the surface, so it is sometimes finished with polishing where needed. Teeth feeling smooth or sensitive afterward is because the tartar has been removed and the original tooth surface is exposed. That said, excessively frequent or rough treatment is not recommended, so having it at an appropriate interval is best. The right interval depends on the state of your gums, so it is a good idea to confirm it at a checkup.
If I brush well at home, can I skip scaling?
Brushing thoroughly every day and using floss matters a great deal, but it is difficult for that alone to fully replace scaling. Once tartar has hardened, brushing alone does not remove it well, and the spaces between teeth and the area below the gumline are particularly hard to manage on your own. That is why combining everyday care with regular scaling helps gum health. People who manage their care well accumulate less tartar and tend to find it easier to keep up. The scaling interval you need differs from person to person, so it is a good idea to confirm what suits your own condition at a checkup.
