How long does scaling take?
“Can I get scaling done on my lunch break and go back to work?” I hear this question often. Scaling for the whole upper and lower mouth usually takes around 20–30 minutes. That said, the time depends on the amount of tartar and the condition of the gums.
| Condition of the mouth | Time it takes |
|---|---|
| Scaling done regularly every 6 months to 1 year | Around 15–20 minutes |
| Put off for more than 1 year, with a lot of tartar | 30 minutes or more |
| Tartar below the gumline and a lot of bleeding | Split into several visits as gum treatment |
On your first visit, X-rays, an exam, and explanations are added, so you'll stay longer. The more regularly you get scaling, the shorter and less painful it is.
What are the steps of scaling?
- I look at the condition of the gums and where tartar has built up. If you have sensitive teeth or have had pain before, please tell me at this point.
- The vibration of an ultrasonic instrument breaks up and removes large pieces of tartar. Water comes out at the same time to cool the heat and wash away debris.
- Hand instruments clean up tartar left between the teeth and along the gumline.
- If needed, the surface is smoothed so that plaque sticks less.
- I show you the spots where tartar keeps coming back and how to clean them.
Why do you need scaling?
Tartar is plaque (a film of bacteria on the tooth surface) that has met the minerals in saliva and hardened like stone. Once it hardens, a toothbrush and floss can't remove it, and more bacteria stick to its rough surface. Scaling is the treatment that removes this tartar so the gums can settle down.
- Gum swelling and bleeding when brushing decrease.
- Bad breath from tartar and bacteria decreases.
- Cavities or cracks hidden by tartar can be found.
- Gum inflammation is stopped before it reaches the bone.
There are also things scaling can't do. It isn't whitening that makes teeth white, and coffee and cigarette stains come off only partly. Tartar stuck deep below the gumline can't be reached by scaling, so separate gum treatment is needed.
What happens if you don't get scaling?
If gum inflammation around tartar (gingivitis) continues, the inflammation moves below the gums and becomes periodontitis, which dissolves the bone supporting the teeth (the alveolar bone). This stage causes little pain, so it often goes unnoticed. People often find out only after teeth become loose or gaps open up, and bone that's been lost doesn't grow back. How fast tartar builds up and the right interval are covered separately in How often should you get scaling?
How we do it at Wonjin Dental
Before scaling, I check the condition of the gums first, and if there's tartar deep below the gumline, I don't push to do it all at once but split it into gum treatment. Scaling under Korean National Health Insurance is covered once a year for those aged 19 and over; otherwise, it's ₩60,000, not covered by insurance (as of September 2026, full fee list). If you're worried it will hurt, read Does scaling hurt? first.
Frequently asked questions
Can I go straight to work after scaling?
Yes. It's mostly done without anesthesia, so you go right back to your day. On the day, your gums may bleed a little and your teeth may be sensitive to cold.
Does scaling open gaps between teeth?
It doesn't grind the teeth, so it doesn't create gaps. As the spaces that tartar was filling and the swollen gums settle down, gaps that were already there become visible.
Can I eat before scaling?
Yes, you can eat before you come. If you brush before coming, the tartar is easier to see. On the day, it's more comfortable to avoid very hot or cold food.
