Hello.

When even a small change in your gums makes your mind shake first,

this is Magok Seoul Dia Dental Clinic,

offering understanding before searching.

If your gums bleed when you brush?

“Did I brush too hard?”

“Do I need to change my toothbrush?”

You’ve probably thought this at least once.

(Most people suspect the toothbrush first here.TT)

But in fact,

the first thing to suspect is your gums.

If you haven’t seen Part 1 of the gum treatment series,

[If your gums bleed when brushing? Self-diagnosis of early gingivitis],

feel free to read that first.

It will make today’s explanation twice as easy to understand.^^

When your gums bleed or feel uncomfortable like this,

the first thing that comes to mind is scaling.

In fact, scaling

is indeed the starting point of gum treatment.

It removes visible tartar and bacteria from the outer surface of the teeth

and the gumline,

which is basic cleaning that helps reduce gum inflammation.

But if you still

keep bleeding even after scaling,

and your gums feel swollen every time you brush?

This does not mean “the cleaning was incomplete,”

but rather that the problem has gone deeper into the gums.

It’s like a room is sparkling clean,

but there is still a smell coming from somewhere in the house...

Gums are the same.

The outside may look clean, but inflammation may still

remain deep inside.

From this stage on,

scaling alone, which only cleans the surface, is not enough,

and treatment that directly cleans deep inside the gums is needed.

That is where root planing and curettage come in.

What is root planing?

  • Treatment that smooths out uneven tooth roots

Magok Dental_ root planing

When gum disease progresses, bacteria and tartar stick to

the root surface of the tooth, making it rough.

This rough surface becomes a “base” that lets bacteria

stick even more easily,

and the gums are unable to reattach,

so inflammation keeps recurring.

[Root Planing] is a treatment that carefully scrapes away

this roughened tooth root,

one by one, and smooths it down.

Simply put, it is like leveling the ground so the gums can attach again.

Dust gathers more easily on uneven ground, right?

Teeth are the same.

How is curettage different?

-Treatment that removes inflamed tissue inside the gums

Magok Dental_curettage

[Curettage] is needed when the problem is not the tooth,

but the tissue inside the gums themselves.

When inflammation lasts a long time,

the gum tissue becomes diseased and can no longer recover on its own.

In this case,

even if you clean the outside thoroughly,

pus and inflammation keep recurring from inside.

Curettage is a treatment that directly removes this diseased gum tissue

and creates an environment where new gum tissue can grow again.

Just as dead tissue must be cleaned away from a wound for new skin to grow,

the same is true for gums.

Why are the two treatments often done together?

Bacteria hide in both the teeth

and the gums at the same time.

That is why, in actual treatment,

root planing to clean the tooth roots,

and curettage to clean inflamed tissue inside the gums

are often needed together.

These two treatments are not about which one is stronger,

but about solving different problems.

In other words, it is not just simple cleaning,

but treatment that changes the environment itself.

These are the cases where it is definitely needed

If you have these symptoms,

root planing and curettage are needed.

  1. Bleeding continues even after scaling

  2. Gums frequently swell and throb

  3. Pus, bad breath, and a foreign-body sensation

  4. Gums appear to be receding

This is not just sensitivity,

but may be an abnormal sign that periodontitis

has moved to the next stage.

Let’s summarize it at a glance

Scaling is the first step in gum treatment.

After that,

root planing, which smooths the tooth roots,

and curettage, which removes diseased gum tissue,

may be needed.

The goal is one thing.

To create an environment where the gums can become healthy again.

Gum disease quietly,

painlessly,

and slowly melts away bone.

That is why it must be stopped sooner.
