How is the scaling interval decided?
It is usually set between 6 months and 1 year, and brought forward depending on how quickly tartar builds up and the condition of the gums. I do not start by naming half a year on the calendar. I set the interval by looking at how much has built up now, whether your gums bleed when you brush, and whether you have ever had gum treatment.
| Gum and tartar condition | Recommended interval |
|---|---|
| Almost no buildup and calm gums | Once a year |
| An average mouth | 6 months to 1 year |
| Builds up quickly, or frequent bleeding when brushing | 3–6 months |
| Has had gum treatment before | Individually, according to the condition of the gums |
The interval is decided by your gums, not the calendar. The reason not to put it off just because it does not hurt is that the warning signs are weak while bone is being lost.
Why does tartar form even if I brush well?
Tartar is plaque (a thin film of bacteria that sticks to the tooth surface) that has hardened after meeting the minerals in saliva, so a toothbrush cannot remove it. “I brush hard, so why do I get tartar?” It is not because you are lazy, but because once it hardens, a toothbrush cannot get it off.
The place plaque is most likely to remain is not the chewing surface but the border where the teeth meet the gums. If you tilt your toothbrush slightly toward the gums to clean that gap, and clean between the teeth with an interdental brush or floss, you can clear it away before it hardens.
Are some people more prone to tartar buildup?
Yes. Even with the same care, the speed of buildup differs from person to person.
- When the teeth are unevenly aligned or tightly spaced, leaving surfaces the toothbrush cannot reach
- When saliva is high in minerals, so plaque hardens quickly (it builds up especially on the inside of the lower teeth)
- When smoking or drinking often leaves the mouth dry
- When gum inflammation makes it easy for bacteria to settle
For these people, simply shortening the interval can do a lot to keep gum inflammation from getting worse. If tartar keeps building up in the same spot, we check together how to clean that area at your checkup.
What happens if I put off scaling?
Bacteria stay around the tartar, and gum inflammation can progress to periodontitis. At first, it is just bleeding when you brush or gums that swell and then settle. If that continues, the inflammation goes deeper into the gums, the bone holding the teeth (alveolar bone) weakens, and the teeth may become loose or gaps may appear between them.
At this stage, scaling alone is not enough, and gum treatment that removes tartar from deep inside the gums becomes necessary.
Is it okay if my teeth are sensitive and my gums bleed after scaling?
In most cases, it is a normal reaction that settles within 1–2 days. Surfaces and gums that were covered by tartar are exposed and feel sensitive, and gums that were inflamed bleed. The more tartar you had, the stronger the sensitivity feels.
On the day, cut back on very cold or hot foods and spicy or salty foods, and avoid smoking and drinking for a few days. If the bleeding is light, try not to keep spitting. Repeated pressure in the mouth makes the bleeding last longer. If bleeding, pain, or swelling lasts more than a few days, please come back.

Frequently asked questions
Does scaling wear down my teeth?
No. It removes the tartar stuck to the tooth surface, so it does not grind away the tooth itself. The sensitive feeling comes from surfaces that were covered being exposed.
It feels like there are gaps between my teeth after scaling.
In many cases, as the tartar that was filling the gaps is removed and swollen gums settle down, spaces that were already there become visible. Scaling did not create the gaps.
Does using an electric toothbrush reduce tartar?
If you hold it properly against the gum line, it helps reduce plaque. However, tartar that has already hardened will not come off even with an electric toothbrush, so regular scaling is still needed.
Should I get scaling even if I have implants or crowns?
Yes, it is a good idea. Tartar also builds up around implants, and if left alone, the surrounding gums and bone can become inflamed. We proceed carefully so the surfaces of the restorations are not damaged.
