Hello~
I’m Lee Ju-ri, chief director of Seoul Bardi Dental Clinic.
I don’t like my facial line because my mouth looks protruded.
Orthodontic consultations are most often about protruding mouth concerns.
A condition where the upper teeth look relatively more protruded is called a protruding mouth.
We also describe it as the mouth sticking out noticeably~
However, there are different types of protrusion.
In some skeletal cases,
orthognathic surgery may be necessary.
Can protruding mouth correction be done without surgery?
Today, I’ll explain the differences between these two methods and the criteria for choosing one.
What Is a Protruding Mouth?
A protruding mouth is not simply when the upper lip sticks out.

250120 Protruding mouth where only the upper teeth stick out
The position of the upper jaw, lower jaw, and teeth
Whether the lips protrude
The harmony between the nose and chin
It is evaluated in terms of the overall facial balance and harmony~
But if you have these symptoms, it may be worth suspecting it!
-
The lips are hard to close and are always slightly open
-
The line from under the nose to the chin is not smooth (from the side view)
-
You look strong or your chin seems small
-
Both the upper and lower teeth are inclined forward

250218 An X-ray for checking the side view of the teeth is not taken for no reason~
In most cases, orthodontic treatment that moves only the teeth,
without surgery, is sufficient.
When only the teeth are slightly protruded (dental protrusion)
When lip protrusion is not severe and the nose-chin line is relatively harmonious
When the issue can be resolved by extracting teeth and moving them inward
When the jawbone position itself is normal but only the teeth are tilted forward
Most treatments for protruding mouth correction are extraction-based orthodontics, where teeth are removed to create space.
As the mouth retracts,
the lip line becomes clearly more refined, and the side profile also improves neatly.
A strong-looking impression can become a softer one~
However, in cases like this,
there are limits even with orthodontic treatment,
and surgery may be necessary!

250228 Skeletal protrusion where the jaw itself sticks out
Orthodontic treatment that moves the teeth can improve the condition by about 2–4 mm.
However, as in the photo, skeletal protrusion where the upper jawbone itself protrudes has its limits.
-
Skeletal protrusion where the upper jaw itself protrudes significantly forward
-
Cases where the teeth were moved far back but lip protrusion improved very little
-
Cases accompanied by skeletal abnormalities such as underbite, facial asymmetry, or open bite
Because no matter how much the teeth are moved,
the bones themselves cannot be moved with orthodontics alone~
In such cases, you may have heard of this before.
Only when orthognathic surgery, such as two-jaw surgery, is combined with orthodontic treatment can the root problem be addressed.
Diagnosis is key.
Treatment for a protruding mouth is not simply a matter of whether orthodontics alone is possible or not.

Many people send a face photo and ask,
Can protruding mouth correction be done without surgery?
It is difficult to determine from the photo alone.

250210 It’s hard to judge from the side view alone!~
It is diagnosed through detailed X-rays and facial line analysis.
It is also necessary to determine whether there are any problems with the temporomandibular joint.
Depending on the patient’s situation, surgery may feel burdensome
(for academic reasons, employment, and so on),
so some people may be satisfied by reducing protrusion to a certain extent through orthodontic treatment.
Since this can be determined through individual analysis of the skeletal structure, tooth arrangement, and degree of lip protrusion,
please first check which type of protrusion applies to you!
Thank you!
