Guide to the Temporomandibular Joint (TMJ): Physical Therapy for Jaw Pain

Introduction

The temporomandibular joint, known as TMJ, is the joint that connects the jaw to the skull.

It allows you to perform essential movements such as speaking, chewing, or opening your mouth.

When this joint or the surrounding muscles are affected, symptoms such as jaw pain, headaches, neck stiffness, or difficulty opening the mouth may occur.

Physical therapy can help improve joint function and reduce associated muscle tension.

What is the temporomandibular joint?

The temporomandibular joint is located on either side of the head, just in front of the ears.

It is one of the most complex joints in the body because it combines rotational and sliding movements.

For this to work properly, the following must work together:

• the joint itself
• the jaw muscles
• the neck muscles
• some muscles of the skull

When any of these factors are disrupted, discomfort or limited mobility may occur.

How can you tell if you might have a TMJ problem?

Some common symptoms associated with temporomandibular joint dysfunction include:

• jaw pain
• difficulty opening the mouth
• clicking or popping sounds when moving the jaw
• pain when chewing
• tension in the neck and head
• headaches or migraines

In many cases, people initially seek medical attention for headaches or neck pain, and during the evaluation, it is found that the cause is related to the jaw.

Why do TMJ problems occur?

TMJ disorders can have various causes.

Among the most common are:

• muscle tension in the jaw and neck
• bruxism (clenching or grinding of the teeth)
• malocclusion
• stress or prolonged tension
• jaw injuries

In many cases, several factors come into play at the same time.

How can physical therapy help?

Physical therapy aims to improve joint mobility and reduce associated muscle tension.

This may include:

• manual therapy for the jaw
• treatment of the neck muscles
• work on the muscles of the skull
• intraoral techniques when necessary

The goal is to reduce pressure on the joint and improve jaw function.

What does intraoral treatment involve?

In some cases, it is necessary to exercise certain muscles from inside the mouth.

This allows access to deep muscles that cannot be treated from the outside.

Intraoral treatment can help relax the muscles involved in opening and closing the jaw.

Although this technique may be unfamiliar to patients at first, it is often very effective in certain cases.

Can TMJ cause headaches or migraines?

Yes. Problems with the temporomandibular joint can cause tension in the muscles of the skull and neck.

These tensions can lead to:

• headaches
• migraines
• a feeling of pressure in the head

By improving jaw mobility and reducing muscle tension, many people find that these symptoms improve.

Collaboration with other specialists

In some cases, TMJ treatment is provided in collaboration with dentists who specialize in this joint.

This may include the use of splints or an evaluation of other aspects related to the bite.

Coordinated efforts among professionals allow for a more comprehensive approach to the problem.

How many sessions are needed?

The number of sessions depends on each individual case.

Some people see improvement after just a few sessions, while in other cases a more gradual treatment is necessary.

During the initial evaluation, each case is reviewed to determine the most appropriate treatment.

Common Mistakes When Experiencing Jaw Pain

Some people wait to see a doctor because they think the jaw pain will go away on its own.

Other common mistakes include:

• ignoring the symptoms for a long time
• treating only the headache without examining the jaw
• Do not seek medical advice if you have difficulty opening your mouth

A proper evaluation can determine whether the TMJ is involved in the problem.

When should you see a physical therapist for TMJ problems?

It is advisable to seek medical advice when the following symptoms appear:

• persistent jaw pain
• difficulty opening or closing the mouth
• clicking sounds accompanied by pain
• headache related to jaw tension

An assessment allows us to evaluate how the joint is functioning and determine the most appropriate treatment.

TMJ Treatment

If you experience jaw discomfort, pain when chewing, or frequent headaches, a physical therapy evaluation can help determine whether the temporomandibular joint is involved.
