TMJ Physical Therapy Guide: Cold, Heat, Electrical and Laser Therapy, Plus Exercise

TMJ physical therapy aims to regain movement of the jaw joint and neck, correct posture, and lengthen and regulate the strength of the chewing muscles. The Korea Disease Control and Prevention Agency (KDCA, 질병관리청) describes physical therapy, together with occlusal splints, as the most used method in TMJ disorder treatment, and stresses that the effect grows when exercise therapy is done alongside. It is typical to choose the method that suits the symptoms from cold, heat, electrical stimulation, laser and biofeedback, and to receive it over several sessions.

What does TMJ physical therapy aim for?

Muscles that hurt from a TMJ disorder tend to stiffen and shorten, and if you move the mouth less because of pain, a vicious cycle can form in which joint movement decreases further. Physical therapy lowers pain and helps the muscles and joint move naturally again to break this cycle.

The goals the KDCA gives are restoring mobility of the jaw joint and neck, correcting posture, and stretching the jaw muscles and regulating their strength. The jaw and neck move together, so the treatment often extends to neck and shoulder posture as well.

What types of TMJ physical therapy are there?

Which method is used depends on whether the pain began suddenly or is long-standing, and whether the problem is in the muscles or the joint. Two or three may be done together on the same day. The methods used when pain has just begun and when it is long-standing can differ, so the combination of treatments is sometimes changed as things progress.

Cold therapy: to calm swelling and acute pain
Heat therapy: surface or deep heat to loosen stiff muscles and increase blood flow
Electrical therapy: transcutaneous nerve stimulation, iontophoresis and others to reduce pain signals
Laser therapy: applying a laser to painful joint and muscle areas
Biofeedback: seeing muscle tension on a screen or by sound to learn how to relax on your own
Manual therapy: loosening the joint and muscles by hand

Why are physical therapy and exercise done together?

The KDCA explains that the effect grows when exercise therapy is done together, compared with physical therapy alone. Even if the muscles are loosened in the treatment room, repeating the same habits and posture at home makes them tense again easily.

The basic exercises the KDCA introduces are six: resting tongue position, jaw rotation exercise, neck extension, resting position of the neck joints, neck exercise and shoulder posture. Each exercise is done in sets of 6 repetitions, 6 sets a day, with each movement kept within 1 minute, performed according to the method prescribed.

How long do you need to go for TMJ physical therapy?

Physical therapy is usually not finished in one session but is received repeatedly over a period while checking changes in symptoms. The number of sessions needed varies greatly from person to person depending on pain level, duration and how much habits are corrected, so there is no set number from the start.

After several sessions, re-measuring the range of mouth opening and the pain score makes it easy to judge the effect objectively. If there is no change or it gets worse, the treatment method is changed, or a splint or medication is considered alongside. Writing down the difference in pain between treatment days and non-treatment days makes it easier to judge with the clinician which treatment is helping.

What does TMJ physical therapy cost?

Whether each physical therapy item is covered by health insurance can differ, and you can tell whether the treatment you received was covered or non-covered from the insured and non-covered columns of the receipt. At a dental clinic outpatient visit, the copayment for insured physical therapy items is 30% of the total insured medical cost for those under 65.

Because TMJ physical therapy takes many visits, asking at the first visit for the expected number of visits and the copayment per visit makes it easier to estimate the total cost. If you have private indemnity insurance, coverage conditions for physical therapy differ by policy, so check in advance.

Common myths and facts

Myth: If I just keep going for physical therapy, I don't need to do anything at home.

The KDCA explains that the effect grows when physical therapy and exercise therapy are done together. Exercises at home and correcting habits need to go along with it.

Myth: When the jaw hurts, hot compresses are always best.

Both cold and heat are used in physical therapy and are chosen by stage of symptoms. Even for compresses at home, it is good to get guidance from the dentist on which method suits you.

Frequently asked questions

Is TMJ physical therapy painful?

Most of the time it involves a warm or cold feeling and mild electrical stimulation. If the stimulation is uncomfortable, say so right away and have the intensity adjusted. The muscles may feel sore for a while right after treatment, but if the pain lasts, tell the clinic at the next visit.

Is physical therapy received at a dental clinic or an orthopedic clinic?

For TMJ disorders, diagnosis and treatment are often done together at a dental clinic, and physical therapy can be received at a dental clinic equipped with the equipment. If neck and shoulder problems are large, medical care may be received alongside.

What should I do if the jaw exercises hurt at home?

If pain gets worse during an exercise, stop and tell the clinic at the next visit. The KDCA advises not doing one movement for more than 1 minute, so it is important not to overdo it.

Are there people who should not receive electrical stimulation therapy?

Before electrical stimulation therapy, you should tell the clinic in advance if you carry an electronic medical device such as a pacemaker or are pregnant. The clinician will judge whether to switch to another method.

What kind of treatment is biofeedback?

It is a method that shows how tense the muscles are on a screen or by sound so that you learn to relax them on your own. It helps you notice the habit of clenching your teeth during the day.
