[Ttukseom SIO Clinic] Jaw Botox: Is a Square Jaw Always Due to Bone Structure?

[Ttukseom SIO Clinic] Jaw Botox,

Is a square jaw always due to bone structure?

Located 1 minute from Exit 1 of Ttukseom Station.

​

Hello. This is SIO Clinic,

known for excellent Botox treatments in Ttukseom.

​

The jawline plays a surprisingly

important role when considering

the overall impression of the face.

​

Depending on the width and angle

of the jaw, the face can appear

defined or, conversely, emphasize

a wide and angular look.

​

"My face looks

big because of my square jaw."

In fact, many patients

who visit us first consider

the bone structure itself.

​

However, not all square jaws

are caused by bone structure.

​

The shape of the jaw is influenced

not only by bone but also by

fat, soft tissues, and the

development of the masseter muscle,

which is responsible for chewing.

Today, based on these differences,

we will gradually discuss

common questions about jaw Botox.

Square jaw, is it always due to bone?

If you clench your jaw and feel

a hard protrusion below your ear,

it may be due to developed masseter muscles.

​

When the development of these muscles

affects the width and angular appearance

of the lower face, changes can be

considered through non-surgical methods

rather than surgical ones.

​

Jaw Botox works by reducing excessive

muscle contraction, helping to decrease

the volume of the masseter muscle over time.

​

While it does not reduce the size

of the bone itself, in cases of

developed masseter muscles, it can

lead to a softer contour by

alleviating the width of the lower face.

​

Can the habit of clenching your teeth

also affect your face shape?

​

If you have a habit of clenching

your teeth tightly when concentrating

or grinding your teeth during sleep,

you repeatedly use your masseter muscles.

​

Reducing these habits can help

lessen the strain on your jaw,

but there are limitations to how

quickly developed muscles can shrink

solely by correcting the habit,

especially after long-term use.

​

Therefore, if the masseter muscles

are developed, jaw Botox can be

considered if necessary, after assessing

the degree of development.

​

However, if you experience teeth grinding

or jaw discomfort, it is advisable

to identify the underlying cause

rather than focusing solely on

aesthetic concerns.

​

What if one side of the jaw looks

larger than the other?

​

Sometimes, one side of the jaw may

appear wider in photos, or the

jawlines may feel asymmetrical.

For such asymmetry, the cause must

be examined first.

​

While factors like bone structure

or occlusion can be involved,

if it's muscular asymmetry due to

relatively developed masseter muscles

on one side, methods to control

the muscles on that side can be considered.

​

The key is not to apply treatment

identically to both sides, but to

approach it based on the individual's

condition, considering the facial structure

and the degree of muscle development.

​

Rather than just making it smaller,

focus on balance.

It is difficult to consider jaw Botox

solely as a procedure to 'make the

face smaller.'

​

In cases where the masseter muscle

is the cause, it is meaningful for

alleviating the width of the lower face,

but the same results cannot be

expected for all square jaws or

facial asymmetries.

​

At Ttukseom SIO Clinic, we first

examine the factors causing the

jaw's shape and, if necessary,

discuss the appropriate methods together.

​

​

Currently, to celebrate our 1st anniversary,

SIO Clinic has prepared special benefits

for those concerned about their jawline.

​

If you've been concerned about

changes in your jawline but were

unsure of the cause,

start by calmly assessing your

current condition.

​

​

At Ttukseom SIO Clinic, we prioritize

natural changes that consider

individual facial balance over

merely noticeable results.

​

We invite you to resolve your

questions about jaw Botox with us
