When to Get TMJ Care: Symptoms to Treat Right Away and Those You Can Watch

Whether TMJ care is needed is judged by how sound, pain and limited mouth opening overlap. If there is only sound and no discomfort, it is sometimes watched with lifestyle management, but dental care is needed when the jaw catches so the mouth will not open or close, or when pain makes chewing and speaking uncomfortable. In Ministry of Health and Welfare material, a dental professor at the National Health Insurance Service Ilsan Hospital explained that leaving a jaw problem alone during growth can lead to facial asymmetry or bite abnormalities, so adolescents need more careful observation.

Which TMJ symptoms need care right away?

It is best not to delay if jaw movement suddenly locks or pain breaks down daily function. In particular, if the mouth stays open and will not close, the joint may be dislocated and emergency care may be needed.

The mouth catches and will not open, or stays open and will not close
The sound suddenly stops and mouth opening decreases greatly
Pain makes it hard to chew food or speak
Jaw pain and a change in the bite appear after a fall or blow
The jaw area swells with fever, or feeling in the face becomes dull

Which TMJ symptoms can you watch for a few days?

If there is only an occasional click with no pain, or brief stiffness the day after eating tough food, you can cut back on gum and hard foods, rest the jaw, and watch how it goes. The KDCA explains that TMJ disorder symptoms may improve on their own or go up and down.

However, if while watching the symptoms become more frequent, pain does not lessen with rest, or mouth opening decreases, you should then move on to care. Keeping a symptom diary makes it easier to judge when care is needed. Even during the watching period, start reducing habits like clenching and resting the chin on a hand right away.

How should an adolescent child's jaw sounds be viewed?

In the 2015 health insurance analysis released by the Ministry of Health and Welfare, the number of TMJ disorder patients per 100,000 people was highest in the 20s and next in the teens. In the same material, the Ilsan Hospital dental professor explained that during growth pain is not felt strongly and is easy to pass over, so careful observation by caregivers and active treatment are needed.

If your child holds the jaw when yawning, chews on one side only, or the jaw deviates to one side when opening, ask the dentist to look at the jaw joint at the checkup too. If orthodontic treatment is coming up, it is good to have the jaw joint condition checked before starting.

Which medical department treats the jaw joint?

TMJ disorders are treated at dental clinics. Among dental specialties, oral medicine mainly handles jaw joint pain and functional problems, and oral and maxillofacial surgery handles surgical treatment such as joint lavage or surgery; you may also be examined first at a general dental clinic and then referred.

The KDCA explains that pain from nerve, blood vessel, infection or tumor, which are not musculoskeletal causes, is not treated as a primary TMJ disorder. If another condition is suspected, such as a sudden severe headache or pus coming from the ear, also get the relevant medical care.

What is good to prepare before TMJ care?

Diagnosis of a TMJ disorder combines the interview, physical examination, any needed imaging, and an assessment of living environment and psychological state, so organizing your symptoms and habits beforehand lets you convey a lot of information in a short visit.

When and how symptoms began (injury, dental treatment, a stressful event, etc.)
Location and strength of pain, the side that makes sounds, how far the mouth opens
Grinding and clenching habits, and noises during sleep that family members have heard
Medicines you take and your history of past jaw treatment or orthodontic treatment
Dental X-rays or imaging records taken earlier

Common myths and facts

Myth: Even if the jaw hurts, it will all get better with time.

Symptoms can improve on their own, but if pain continues or mouth opening decreases, contributing factors must be found and treated. There is also an explanation that neglect during growth can lead to facial asymmetry.

Myth: The jaw joint is treated only by an orthopedist.

TMJ disorders are diagnosed and treated at dental clinics. Among dental specialties, oral medicine and oral and maxillofacial surgery mainly handle them.

Frequently asked questions

What should I do if my mouth stays open and won't close?

The jaw may be dislocated, so do not force it shut; get care at a dental clinic or an emergency room right away. If the jaw dislocates repeatedly, you must keep up dental care afterward to find the cause.

I have jaw pain. Should I go to a dentist or an ENT doctor?

If the area in front of the ear hurts when chewing or opening the mouth, it is common to have the jaw joint checked first at a dental clinic. If your ears feel blocked or there is pus or dizziness along with it, also see an ENT doctor.

What happens on the first day of TMJ care?

There is an interview about symptoms and habits, a physical examination of mouth opening and joint and muscle tenderness, and imaging if needed. Rather than making an appliance from the first day, a treatment plan is made based on the assessment results.

When is TMJ surgery done?

It is considered when reversible treatments such as medication, exercise, physical therapy and splints are not enough. The NHIS advises discussing this decision with an oral and maxillofacial surgeon who specializes in TMJ conditions.

My jaw hurts only when I'm very stressed.

Stress is named as a factor that raises muscle tension and worsens pain. If jaw pain repeats whenever you are stressed, consider stress management or counseling along with dental care.
