Hello.🤗

I am Dr. Park Yeol,

an orthodontic specialist who has been providing orthodontic treatment at Gangnam Station for 20 years.

During orthodontic consultations,

there is a question patients always ask.

“Doctor, I heard that if you get orthodontic treatment with extractions,

your face will look sunken.”

“Wouldn’t I look older

or have a hollow area around my mouth?”

“I also heard that your face can change to look skull-like,

which sounds ugly.

I’m really torn about whether to do it or not.”

This question

comes up several times a day

in the consultation room at Dr. Prime Orthodontic Clinic near Gangnam Station.

To give the conclusion first,

with extraction orthodontics,

it is rare for the face to become skull-like

or to look sunken.

Rather, in many cases,

the protruding lips and side profile

improve in a balanced way.

However, in rare cases,

if the orthodontic treatment is handled clumsily,

or if the doctor fails to pay careful attention,

such problems can occur.

So it is true that some caution is needed.

Today,

based on more than 20 years of orthodontic experience at Dr. Prime Dental Clinic near Gangnam Station,

I will explain the principles of extraction orthodontics for a protruding mouth

and the actual changes through X-rays and photos.

After hearing the explanation below,

you will feel much more at ease

about side effects such as a sunken appearance or protruding teeth😁

  1. Why extractions are necessary

for patients with a protruding mouth

A protruding mouth is not simply a matter of the teeth being forward;

it is a condition in which the entire upper and lower lips protrude forward.

If the front teeth are angled forward,

it takes effort to close the mouth,

the expression looks unnatural,

and it can create a displeased impression.

In such patients,

the premolars and molars are often also positioned forward,

so the entire mouth area protrudes.

The solution is

to create space for moving the front teeth backward.

Usually, the first premolars on both sides are extracted,

and the front teeth are moved into that space.

This allows

the protruding mouth to recede naturally,

the side profile to soften,

and the mouth to close more easily.

  1. The key is precise control

to stop at the ‘appropriate range’ of front-tooth movement

Do not always move the front teeth back as much as possible!

At Dr. Prime Dental Clinic near Gangnam Station,

when performing extraction orthodontics for a protruding mouth,

we do not simply push the front teeth back without limit;

we move them backward only to the most natural and harmonious position.

Before orthodontic treatment

During orthodontic treatment

Treatment completed

Using the extraction space on both sides,

as the front teeth are gradually moved backward,

the protrusion becomes less noticeable

and the remaining extraction space also gradually decreases.

What matters in this process is

observing two things at the same time.

Important observation points during extraction orthodontics ✔
1. How much the protruding mouth has improved
2. How much residual extraction space remains

When the extraction space is completely closed,

the lips should be adjusted so that they are in their most beautiful state.

What should not happen during extraction orthodontics!
1. If the protruding mouth has receded enough but a lot of extraction space still remains ❌
2. If the protruding mouth is unchanged but the extraction space is almost closed ❌

This kind of delicate balance control

requires extensive treatment experience.

Dr. Prime conducts

periodic X-ray imaging

for precise monitoring.

At Dr. Prime Dental Clinic,

side-profile X-rays are taken periodically during the orthodontic process.

Through this, we thoroughly prevent the following two problems:

1. The mouth moving in too much and becoming protrusive
2. The lips and area around the mouth sinking too much and becoming sunken
We thoroughly prevent both of these!

In the end,

we adjust the treatment so that it finishes in the most natural and comfortable position,

completing a side profile and lip line

that the patient can be satisfied with.

  1. We also manage front-view changes-

We take smile photos often

and compare them

A front-facing photo is taken before orthodontic treatment.

As treatment progresses, front-facing photos are continuously taken.

Treatment completed, beautiful smile completed :)

If only the side profile improves

while the front view looks unnatural,

you cannot say the orthodontic treatment was successful.

After extraction orthodontics,

a comfortable and natural smile

should appear.

Deep nasolabial folds should not become excessive,

and the face should not look haggard because of lost facial volume.

To ensure this,

Dr. Prime frequently checks the patient’s expression even during treatment,

and periodically takes smile photos

to compare.

In closing-

Choosing the right clinic is important for extraction orthodontics

Now that you have heard about the principles of extraction orthodontics for a protruding mouth,

and how doctors manage the orthodontic process,

you may feel somewhat reassured.

There may be many people who are advised to undergo extraction orthodontics because of a protruding mouth,

and for those who have been recommended extraction orthodontics at multiple orthodontic clinics,

you do not need to worry like this.😃

If you are treated by an experienced specialist-
There are far more positive changes than worries about looking sunken.
You can expect improved lip protrusion, a harmonious side profile, and a natural front view.

However, if the protruding mouth is mild and extraction orthodontics is forced unnecessarily,

or if it is left to a doctor with insufficient experience,

side effects can occur.

At Dr. Prime Orthodontic Clinic

near Gangnam Station,

with abundant experience and detailed adjustments,

we create the most natural and harmonious result.
