Jaw Pain When Opening Your Mouth Can Be Treated

Hello.

I am Oh Tae-hoon, director of D-Day Dental Clinic, with the goal of providing treatments that cause as little pain as possible.

“Isn’t it normal for everyone

to hear clicking sounds from their jaw?”

While yawning,

or taking a large bite of a sandwich,

most people simply brush it off

even when they hear a “click” from their jaw.

That is because when they ask people around them,

they always hear answers like, “I get that too.”

But if pain has been added to the sound,

you have already moved beyond the stage of “everyone gets that.”

The area in front of your ear feels sore every time you open your mouth,

and one day, you may find that you can open your mouth

only about the width of two fingers.

At that point, eating becomes a source of concern,

and you even become cautious about speaking.

The jaw is a joint that moves thousands of times a day,

so once discomfort begins,

it can disrupt your entire daily life.

If you are searching for information because of jaw problems,

this article will help you decide

whether it is time to visit a dental clinic.

  1. The stages are completely different when there is only a sound and when there is pain

There is a disc inside the temporomandibular joint

that cushions the area between the bones.

When this disc moves slightly out of position,

it catches and releases as you open your mouth,

causing a “clicking” sound.

It may help to picture a hinge on a door.

When a hinge becomes slightly misaligned,

it may only squeak at first,

but if you continue opening and closing it,

the door may eventually stop closing properly.

The temporomandibular joint follows a similar progression.

Therefore, when there is only a sound without pain,

there are many cases where special treatment

is not immediately necessary.

However, if pain develops,

if you can no longer open your mouth as widely as before,

or if headaches and stiffness in your neck and shoulders also occur,

these are signs that problems with the disc

and the surrounding muscles are progressing.

Distinguishing between these two situations

is the first step in temporomandibular joint care.

  1. In most cases, habits are responsible for damaging the temporomandibular joint

“Why is this happening when I have never been hit or injured?”

Many people ask this question.

However, temporomandibular joint disorders are much more often caused

by the accumulation of small habits repeated every day

than by a single accident.

Grinding your teeth while sleeping

Clenching your teeth unconsciously when concentrating

Enjoying chewy dried squid or crunching hard ice

Chewing only on one side when eating

Resting your chin on your hand

When stress is added to this,

the muscles around the jaw remain tense

and work under strain all day.

The fact that habits are often the cause

can also be good news.

Many people experience significant relief

simply by identifying and correcting these habits.

However, it is difficult to determine on your own

which habits are troubling your jaw.

That is why it is essential to examine your daily habits

as part of the diagnostic process.

  1. Seonjeongneung Station Dental Clinic does not start by talking about surgery

The basic principle of temporomandibular joint treatment

is to let the joint rest

and help it return to its proper position.

Non-surgical treatment comes first:

an occlusal stabilization splint can reduce the load on the jaw,

while medication and physical therapy can relax tense muscles.

Last month, a patient who was very worried

about clicking sounds in their jaw

was told after an examination,

“You do not need a splint at this point.

Let us monitor the condition while correcting your habits.”

Although starting treatment immediately

may benefit the clinic,

I do not believe recommending treatment

that is unlikely to be effective is proper care.

Conversely, when treatment is necessary,

we explain why by showing you the examination results directly.

Treatment should begin only after patients

understand and accept the condition of their jaw,

because treatments that require consistency,

such as wearing a splint, must be continued through to the end.

Let us return to the question from the beginning.

“Doesn’t everyone have that?”

A sound alone may be something that can occur.

But pain is different.

Pain is a signal from the temporomandibular joint

that it is having difficulty coping any longer,

Fortunately, when you visit us at this stage,

most cases can improve without surgery.

You can fully regain a daily life

where even a big yawn in the morning causes no concern.
