My jaw hurts when I open my mouth... If I leave it untreated, will my face become crooked?

Caused by teeth grinding, clenching, and similar behaviors

According to Seoul National University Hospital, the temporomandibular joint is located between the mandible (jawbone) and the temporal bone (skull), serving as the joint that connects these two bones, and is situated just in front of both ears. It acts as the central axis for all jaw movements and is supported by jaw muscles and ligaments. However, abnormalities in the function of this temporomandibular joint caused by various factors are referred to as temporomandibular joint disorder.

The causes of temporomandibular joint disorders are diverse.

Bad oral habits such as chewing on only one side, clenching teeth, and enjoying hard foods, as well as sleep habits like grinding teeth at night or sleeping face down, also have an impact. Additionally, it can be caused by chronic fatigue, traffic accidents, or trauma from sports. Spinal conditions (such as spinal imbalance or cervical disc issues) are also common.

Facial asymmetry, as well as clicking sounds.

What are the symptoms when temporomandibular joint disorder occurs?

Generally, tension in the facial and neck muscles connected to the jawbone causes headaches and neck pain. The temporomandibular joint on the affected side may not open properly, leading to facial asymmetry. Additionally, opening and closing the mouth can be uncomfortable, and a clicking sound may occur when opening the mouth.

Stiffness and soreness extend from the chin to the neck, shoulders, and head, and when trying to put the remaining fingers (excluding the thumb and index finger) of the hand into the mouth in a vertical position, it doesn't go in easily. Yawning or opening the mouth wide makes it difficult to close the mouth properly, and there is a sensation of a headache along with decreased concentration. Symptoms such as dizziness, ringing in the ears (tinnitus), tears, sensory paralysis, and changes in appetite may also occur.

As the condition worsens, pain becomes more frequent, and in cases of arthritis, the joints hurt and chewing food or moving the jaw becomes uncomfortable. When arthritis deteriorates, stiffness of the temporomandibular joint occurs, making it difficult to open the mouth widely, and eating becomes challenging. The temporomandibular joint and jaw muscles are functionally closely related, so it is common for joint diseases and jaw muscle disorders to occur together.

Lifestyle habits to prevent temporomandibular joint disorders

Temporomandibular joint disorders are treated with various therapies such as acupuncture, Chuna therapy, and manual therapy, but it is important to prevent TMJ disorders through healthy habits in daily life.

To prevent temporomandibular joint disorders, it is especially important to correct lifestyle habits, including dietary habits. Avoid the intake of caffeine, salt, nitrates, alcohol, and foods containing tyramine. Limit the consumption of hard and chewy foods (such as squid) whenever possible, and be careful not to open your mouth too wide. Additionally, avoid excessive jaw exercises.

Avoid napping during the day as much as possible to ensure restful sleep at night, and engage in appropriate daytime activities to get sufficient sleep at night. Be cautious about alcohol consumption and medication intake before bedtime. In addition to practicing relaxation exercises to relieve stress and reduce tension, always strive to maintain proper posture in daily life.
