Hello.

We ease the fatigue of the day with sleep,

and we take care of your dental fatigue at Magok Seoul Dia Dental Clinic.

Last time, we introduced the snoring appliance,

which many of you were curious about.

If snoring is the main culprit that disrupts sleep,

there is another unwelcome guest.

That is bruxism.

Do you ever wake up in the morning with a stiff jaw

or sensitive teeth?

Most people brush it off, thinking, “I must have tossed and turned a lot yesterday,”

but in fact, it is often caused by unconsciously

clenching or grinding the teeth during sleep.

If snoring disturbs the person sleeping next to you,

bruxism is the enemy that wears down your teeth and temporomandibular joints.

Today, we will explain in an easy way why bruxism occurs, what problems it can cause, and how a bruxism appliance helps protect your teeth.

Bruxism is not just a simple sleep habit

Maggok Dental_Bruxism during sleep

Bruxism is often thought of as just a “sleep habit.”

However, in dentistry, it is regarded not as a simple habit but as a condition.

That is because bruxism is not just a noise problem that happens while sleeping,

but a signal from the body that appears as several factors overlap.

For example, when you are under a lot of stress, the jaw muscles

tense up unconsciously, causing you to clench your teeth even at night.

Also, if you do not fall into deep sleep and keep tossing and turning,

it becomes easier to grind your teeth.

In addition, if the teeth do not fit together evenly,

the force concentrates on one side, making grinding even worse.

In the end, bruxism is not just a sound,

but something you should see as a sign that strains the teeth and temporomandibular joints and turns on a warning light for your health.

Problems if bruxism is left untreated

“You’re not saying bruxism could really cause serious problems, right?”

But in reality, it leaves behind various problems.

  1. Cracks and fractures in teeth

The pressure applied in one night can be as high as 200 kg.

A small crack can gradually grow and eventually cause the tooth to break.

  1. Temporomandibular joint disorders

If your jaw feels stiff every morning, or if you hear a “clicking” sound

when opening your mouth, it means the temporomandibular joint has been strained.

  1. Headache, neck, and shoulder pain

The tension in the teeth and jaw travels through the muscles and extends to the head and shoulders.

You end up in a situation where you wake up feeling even more tired.

In other words, bruxism is a habit that affects not only the teeth but also your overall physical condition.

Why a bruxism appliance is needed

The answer is very simple.

It is the bruxism appliance, also called a night guard.

Simply put, think of it as a shield placed over the teeth.

When you wear this appliance, it prevents the teeth from directly colliding

with each other, helping to prevent wear and cracks.

It also distributes force evenly so that it does not concentrate on one side,

which helps relax the jaw muscles and reduces the impact

transmitted to the temporomandibular joint, preventing pain.

In other words, a bruxism appliance is less of a special treatment tool and more of a preventive device.

Since you cannot immediately stop the habit of grinding your teeth,

the smart approach is to protect the teeth and jaw instead.

How exactly does it work?

  1. Pressure distribution

The appliance absorbs the force generated during bruxism and spreads it out,

preventing excessive force from being applied to only specific teeth.

  1. Joint stabilization

It helps keep jaw movement consistent so the joint does not twist.

This reduces symptoms such as clicking sounds in the jaw or stiffness.

  1. Muscle relaxation support

As continuous tension is relieved, the muscles learn how to “let go” of the force on their own.

This reduces the pain and fatigue caused by it.

In other words, a bruxism appliance absorbs and distributes the pressure applied to the teeth,

protecting the teeth, temporomandibular joint, and muscles at the same time.

Key summary of the need for and principle of a bruxism appliance

  1. Bruxism is a sign that threatens the health of the teeth and temporomandibular joint

  2. It can lead to tooth fractures, temporomandibular joint disorders, and even headaches

  3. A bruxism appliance is a customized shield that protects the teeth and jaw

  4. It can prevent major treatment costs with a small amount of inconvenience and expense

Bruxism is common, but it is never a sign to take lightly.

If you prepare not only for snoring but also for another sleep intruder, bruxism,

you can protect not only your dental health but also your overall health.
