Hello,

We are Seoul Dia Dental Clinic in Magok-dong,

promising honest and meticulous care.

The Lunar New Year holiday has ended,

and daily life has started again.

Many of you probably found it hard

to get out of bed even after waking up in the morning.

We understand that feeling very well.

In fact, one of us is going through the same thing.

Still, let’s do our best! haha

As the first step back to everyday life,

we hope you can begin lightly with

Seoul Dia Dental Clinic in Magok-dong’s

dental story,

so let’s get started in earnest.

Last time, we looked at the [cause of amalgam discoloration].

If you missed it, please check it through the link below.

When looking in the mirror, the molar catches your eye.

“Wow, this is old..."

“Do I need to replace it...?”

“Wouldn’t switching to resin be enough?”

Many people think this way.

But here is one important point.

Replacing amalgam is not simply a treatment

that swaps one material for another.

The treatment method changes depending on the condition of the tooth,

and the material used also changes accordingly.

So today,

filling? inlay? crown?

When is each treatment needed,

and what materials are used?

We’ll explain one by one in an easy-to-understand way.

Now, focus~!! Let’s begin right away.

What We Check First After Removing Amalgam

Amalgam removal at Magok-dong dental clinic

When amalgam is removed,

the condition of the tooth that was not visible from the outside is revealed.

  • Whether decay has progressed further

  • Whether the tooth structure has weakened

  • Whether there are any cracks

This is what determines the direction of treatment.

It’s similar to peeling off wallpaper and finally discovering

whether there is mold or whether the wall has rotted.

Treatment Methods Depending on Tooth Condition

When Replacing Old Amalgam

  1. If the damage is minimal → Filling treatment

If the decay is small and the tooth is strong,

it can be restored with filling treatment.

This is done by filling the area where amalgam was removed

with a filling material,

and in this case,

a tooth-colored composite resin is often used.

It offers excellent aesthetics,

short treatment time,

and is hardly noticeable.

From the tooth’s perspective,

it is like a “simple repair job.”

  1. If the damaged area is wide → Inlay treatment

If the damaged area is wide, filling alone may not be enough

to support the remaining tooth.

In that case, an inlay prosthesis may be necessary.

It is made like a puzzle piece

and placed precisely to fit the tooth,

using materials such as ceramic, gold, or reinforced resin.

Compared with fillings, inlays

are better at distributing chewing forces

and are durable enough for long-term use.

In particular, Seoul Dia Dental Clinic’s inlays

are completed on the same day using Just Scan.

  1. If the decay is deep and the tooth has weakened → Crown treatment

If the tooth structure has weakened,

the entire tooth is covered and protected with a crown prosthesis.

A crown prosthesis

is strong against chewing forces,

prevents tooth fracture,

and restores function.

It is like putting a sturdy exterior

on a house whose outer walls have become weak.

The materials used include

zirconia, all-ceramic, gold, and PFM.

  1. If it has progressed to the nerve → Crown after root canal treatment

If the decay has reached the nerve,

root canal treatment is needed first.

After that, the tooth is covered with a crown

to protect the weakened tooth.

It is a somewhat larger repair process,

but an important step for using the tooth for a long time.

If we summarize today’s content to the essentials, it is this.

  1. Check the tooth condition after amalgam removal

  2. If the damage is small, recovery with resin filling is possible

  3. If the area is wide, inlay treatment may be needed

  4. If the tooth is weak, protect it with a crown

  5. If it has progressed to the nerve, root canal treatment followed by a crown is necessary

  6. The material depends on aesthetics, strength, location, and condition

Replacing amalgam

is not simply a treatment that changes the filling material,

but a process of protecting the tooth again.

If you have been concerned about old amalgam,

it may be a good idea to visit a Magok-dong dental clinic,

check the condition,

and hear an explanation of the treatment method and materials

that suit your tooth.

Even just checking can make you feel much more at ease.

This concludes the amalgam series.

Have a happy, smiley day today.

Then, I’ll wrap up here~^^
