Hello.

We provide honest treatment! Clear explanations!

This is Magok Seoul Dia Dental Clinic.

Have you ever had the experience of taking a photo,

smiling by just slightly lifting the corners of your mouth?

You make a V sign, you make a heart,

but in the end, you keep your teeth carefully hidden!

The reason is actually very simple.

Because coffee, tea, cola, and the like that we drink every day

slowly stain our teeth yellow over time.

But this is absolutely nothing to be embarrassed about.

It is a change everyone naturally goes through.

Magok Dental_Before and after whitening

In fact, people’s interest in teeth whitening

has remained steady throughout history.

In ancient times, people tried to clean their teeth with vinegar or soda,

and now, much more intelligently and safely,

we can regain a bright smile through whitening.

So today, we prepared this!

“How does teeth whitening restore color?”

We’ll explain the principles of whitening treatment in an easy and fun way,

in the unique style of Seoul Dia Dental Clinic near Magok Station.

Shall we slowly bring out the confident smile hiding behind your lips now?

Why do teeth turn yellow?

Magok Dental_causes of tooth discoloration

Tooth discoloration is more common than you might think.

Strongly pigmented drinks like coffee, tea, wine, and cola that we drink every day,

smoking as a habit,

days when you skip brushing (everyone has those, right?)

pulpitis, which causes inflammation in the tooth root,

and even certain medications or congenital factors!

When these various reasons overlap,

teeth gradually turn yellow little by little each day.

At first, you may not notice it, but at some point, the smile in photos

starts to feel duller and darker than before.

And once discoloration begins,

simply brushing more diligently

is not enough to restore the original bright state.

That is why teeth whitening treatment is needed—

a treatment that cleans away deeply embedded staining substances without shaving or damaging the teeth.

How does teeth whitening make teeth white?

Magok Dental_Pigment buildup in tiny pores on the enamel surface

Teeth whitening is a dental treatment that

restores yellowed teeth to a brighter, clearer color.

Many people ask, “Do you shave the teeth or coat them?”

but the core of teeth whitening is a chemical bleaching action that does not damage the teeth.

If you look closely at a tooth,

it appears smooth on the outside, but the enamel surface

contains many tiny pores.

Through these small pores, pigments from coffee, wine, carbonated drinks,

and tar from cigarettes seep in over time,

which is why teeth gradually look more yellow.

The main ingredient here is

hydrogen peroxide (H₂O₂) or carbamide peroxide!

When these whitening ingredients penetrate the tooth surface and interior,

they combine with the substances that intensify stains and break them down into smaller molecules.

Simply put,

it is a process that invisibly removes the “stains” hidden inside the teeth

from the inside out.

And it doesn’t end with removing the pigment.

It also helps clean up the tooth surface more neatly and densely,

making it harder for new stains to stick again.

So, shall we summarize the whitening principle at a glance?

  1. It does not shave the teeth.

  2. It chemically breaks down pigment from the inside.

  3. It makes the tooth surface cleaner and helps prevent staining.

In other words, teeth whitening is

a smart treatment that restores only the color

while keeping the tooth structure intact.

However, not all teeth can achieve the same whitening effect.

Because the cause of discoloration, tooth condition, and sensitivity

vary from patient to patient, the most suitable whitening method also differs.
