Hello.

This is 서울디아치과,

responsible for healthy smiles

in the Magok Station area.

Just last week,

we had to battle the sweltering heat

that left us drenched in sweat.

But surprisingly, after Ipchu,

the temperature dropped quite a bit, didn’t it? Haha.

Autumn will arrive before we know it,

and what should you do during the change of seasons?

Get a dental checkup!

During the seasonal transition, when immunity tends to decline,

now is the perfect time to visit the dentist

if you have been putting it off.

The breeze is also becoming pleasantly cool,

so you can visit us comfortably.

(The inside of the dental clinic is even cooler ^-^)

Anyway~ haha

we are starting a new series today.

It is about a symptom that many people have experienced at least once:

temporomandibular disorder.

“My jaw makes a clicking sound.

Is it okay to just leave it alone?”

Recently, more people have been contacting us about this symptom.

When there is only a sound and no significant pain,

many people wonder whether it is really necessary to visit a hospital

and end up ignoring it.

However, temporomandibular disorder

can begin with a small sign

and, at some point, progress to difficulty opening the mouth

or chronic headaches.

Today, we will explain step by step, starting with the basics,

what temporomandibular disorder is

and how problems can develop within its structure.

What Is the Temporomandibular Joint?

The temporomandibular joint

is called the TMJ (Temporomandibular Joint).

It is the joint located directly in front of the ear,

where the lower jawbone and skull meet.

It is involved in every movement we make when we chew food,

talk,

and open and close our mouths.

It is one of the most frequently used joints in the human body,

moving continuously thousands of times a day.

Inside this joint is a disc (articular disc)

that cushions impacts between the bones.

When this disc

starts to gradually move out of position,

temporomandibular disorder begins.

Magok Station Dental Clinic_Temporomandibular Disorder

Temporomandibular disorder (TMD, Temporomandibular Disorder)

refers to a condition involving pain or functional abnormalities

in the temporomandibular joint and surrounding muscles.

It is not simply a problem of jaw pain.

The muscles surrounding the temporomandibular joint,

as well as the ligaments, bones, and disc,

can all be affected, making it a complex condition.

Temporomandibular disorder

can generally be divided into two types.

1. Problems with the Joint Itself

This occurs when the disc moves out of position

or changes develop in the joint structure itself.

A clicking sound when opening the mouth

or being unable to open the mouth beyond a certain point

are symptoms that may occur in this case.

2. Muscle Problems

This occurs when the muscles that move the jaw

become excessively tense

or fatigued.

Unconscious habits,

such as teeth grinding and jaw clenching,

are major causes.

These two types often occur together.

Why Does It Develop?

Magok Station Dental Clinic_Pain Caused by Poor Posture

It is difficult to identify just one cause

of temporomandibular disorder.

As with many conditions,

multiple factors often work together. T.T

1. Teeth Grinding and Jaw Clenching

Habits such as grinding your teeth during sleep

or tensing your jaw when you are under stress.

If these behaviors are repeated,

the temporomandibular joint and surrounding muscles

are continuously overloaded.

A considerable number of patients with temporomandibular disorder

also grind their teeth or clench their jaws.

2. Poor Posture

Postures such as holding your neck forward

or resting your chin on your hand.

If these postures continue for a long time,

unbalanced forces are placed on the temporomandibular joint.

3. Trauma

This includes cases in which the jaw receives a direct impact,

such as from a traffic accident or fall.

4. Dental Occlusion Problems

An improper bite

or a change in tooth height after dental treatment

can also affect the temporomandibular joint.

5. Stress

Stress can trigger jaw clenching and muscle tension,

making it an important factor

that can worsen temporomandibular disorder.

Is Temporomandibular Disorder Treated at a Dental Clinic?

Magok Station Dental Clinic_Dental Consultation

“Isn’t a temporomandibular joint problem treated by an orthopedic surgeon or an otolaryngologist?”

Many people think this way.

Temporomandibular disorder

is diagnosed and treated at a dental clinic.

This is because the jawbones and the bite of the teeth

directly affect the temporomandibular joint.

At a dental clinic,

we carefully evaluate the condition of the temporomandibular joint

through occlusal analysis and imaging tests

and recommend a treatment approach suited to the cause.
