Hello.
We are Blanche Dental Clinic, where your smile becomes a work of art.
Have you ever suddenly looked in the mirror or taken a photo and worried that the left and right sides of your face do not match?
Facial asymmetry may seem like just an external issue,
but it can also be a warning sign from the temporomandibular joint, the central axis of our body.
Today, we’ll look at simple self-check methods you can do at home, along with the causes of facial asymmetry.


Many people hear a clicking sound from the temporomandibular joint or feel a dull pain when opening their mouth.
If these symptoms are left untreated, only one side of the jaw joint may wear down or become misaligned,
which can lead to facial asymmetry as the center line of the face collapses.
Because this goes beyond changes in appearance and can also cause functional discomfort,
many people report psychological stress.


When people hear about facial asymmetry treatment, some become scared,
thinking only of major procedures like double-jaw surgery.
But in reality, most cases are caused by an abnormal jaw-joint position or muscle asymmetry due to poor chewing habits.
In other words, if the cause is identified accurately,
it can often be improved without surgery through jaw-joint correction or muscle treatment.

The most basic way to check jaw-joint health is to assess the mouth-opening range.
Try placing three fingers vertically into your mouth and see whether they fit comfortably.
If even two fingers are difficult to fit, or if you feel pain when opening your mouth,
this may be a sign that there is a problem with the muscles around the jaw joint or the disc.


The path your mouth takes when opening is also very important.
If it does not open straight down vertically, but instead opens in a zigzag, S-shaped path, or
swings sharply to one side, it means the left-right balance of the jaw joints has been disrupted.
This is a typical early sign of facial asymmetry, which can appear when one side of the jaw-joint disc gets caught first
or when muscle strength is imbalanced.


Place your hand just in front of your ear while opening and closing your mouth.
An occasional click may be temporary, but if the sound continues along with pain, or if you hear a gritty, sand-like sound,
it may mean degenerative changes in the jaw joint are progressing.
The sound is a kind of structural signal from the jaw joint, so you should pay close attention to it in everyday life.

If your jaw feels especially heavy when you wake up,
and you have pain near the temples, you should check your oral habits from the night before.
Unknowingly clenching your teeth tightly or grinding them places enormous stress on the jaw joint and worsens asymmetry.
It is more common than you might think for unexplained headaches or shoulder stiffness to originate from jaw-joint problems.


The habit of chewing only on one side causes only one jaw muscle, the masseter, to develop abnormally.
This can lead to muscular facial asymmetry, and over time it accelerates wear of the jaw joint on the more-used side.
When eating, check whether you are consciously using both sides evenly,
and whether you may be avoiding one side because of discomfort in certain teeth.


Blanche Dental Clinic does not simply look at asymmetry visible on the surface.
Through 3D CT and detailed examinations, we identify the root cause,
such as whether the jaw-joint space is symmetrical and whether muscle strength is unevenly distributed.
Rather than excessive surgery, we help patients regain a healthy facial line through conservative corrective treatment that restores the jaw joint to the proper position
and through guidance on improving daily habits.

If you are worried about facial asymmetry, don’t just look in the mirror alone and feel upset.
It is important to first check the condition of your jaw joint with the self-check methods shared today.
If you find and manage small changes early,
you can protect a healthy jaw joint and a beautiful smile for life.
We hope you can gain clearer management tips through the doctor’s detailed explanation in the video!
