Jaw Joint (TMJ) Treatment

What is a jaw joint (TMJ) problem?

Temporomandibular disorders (TMD) are an umbrella term for pain and functional problems of the jaw joint, the chewing muscles and the structures that connect them: displacement of the joint disc (clicking, sometimes locking), degenerative changes inside the joint, muscle-related pain (myofascial pain) and combinations of these. The international DC/TMD classification bases the diagnosis on clinical examination — the complaint, the location of pain, signs during movement and palpation findings are assessed together. Symptoms, causes and a patient-friendly explanation are in a separate article.

Which symptoms call for an assessment?

Important: not every click is pathology. A painless, stable click is common in the population and does not by itself need treatment; an assessment is needed when there is pain, impaired function or changing symptoms.

• Pain in front of the ear or in the jaw — worse with chewing, talking or in the morning
• Limited mouth opening, the jaw deviating to one side on opening, or a feeling of “locking”
• Clicking or grating — especially together with pain, catching or impaired function
• Discomfort when chewing, avoiding hard food
• Tired, tense jaw muscles in the morning, headache in the temple area
• Signs of clenching and grinding — tooth wear, scalloped tongue edges, sensitivity
• A feeling of fullness or noise in the ear — once an ENT cause has been ruled out

How is a TMJ problem assessed?

The diagnosis starts with a clinical examination, not with an image. In our clinic the assessment runs in consecutive stages and only the necessary steps are added.

1. 1

   Complaint and medical history

   Location and character of the pain and when it gets worse; history of clicking and locking; sleep, stress, clenching; trauma, previous orthodontic and prosthetic treatment; systemic diseases and medication.

2. 2

   Clinical examination

   Facial symmetry, teeth, wear facets, soft tissues; the range and path of mouth opening (deviation, limitation), lateral and protrusive movements.

3. 3

   Muscle and joint palpation

   Tenderness of the chewing muscles (masseter, temporalis and others) and the joint area; the character and timing of sounds during movement — following DC/TMD principles.

4. 4

   Occlusal assessment

   Tooth contacts, interferences in sliding movements, the wear pattern; models or an intraoral scan when needed. Occlusion is recorded as a finding, not automatically as “the cause”.

5. 5

   Imaging — only when indicated

   CBCT when bony changes are suspected, MRI for questions about the disc and soft tissues; not taken routinely for every patient.

6. 6

   Axiographic / functional analysis — when needed

   Recording the movement paths of the lower jaw: asymmetry, restricted movement and parameters for restorative planning.

7. 7

   Individual treatment plan

   According to the findings: education and self-care, load reduction, a splint, physiotherapy or referral to another specialist when needed; a restorative/occlusal plan only when indicated.

What does axiography provide?

Axiography is a functional analysis method that records the opening, closing, protrusive and lateral movements of the lower jaw. It shows the movement pattern of the joint (including the difference between the two sides), traces that point to the behaviour of the disc during movement, and the individual parameters needed for occlusal planning. It is not a “device that settles the diagnosis 100%” — it complements the clinical examination and is used above all in complex restorations, tooth wear and full-mouth plans.

Imaging: CBCT, MRI — for whom and when?

The great majority of TMJ problems are diagnosed clinically; imaging is ordered when there is a question that would change the outcome. CBCT shows the bony components of the joint — condyle shape, cortical bone, degenerative changes, trauma; MRI is superior for the disc and soft tissues. For a painless click or simple muscle pain imaging is usually unnecessary.

When can splint therapy be used?

A splint (occlusal appliance) is not a universal solution. Its purpose depends on the clinical picture: reducing the load on the muscles and joint, softening the effect of night-time clenching, managing symptoms in some disc problems, or testing the jaw position before a restorative plan. The design also differs by purpose (stabilisation splint, deprogrammer, anterior repositioning appliance). A splint is used under supervision — for a defined period, with periodic adjustments; it is stopped when the complaint resolves or the goal is reached. Systematic reviews and network meta-analyses show that in painful disc displacement conservative approaches (education, exercises, a splint) are often sufficient and invasive interventions are not the first choice.

Bruxism and the jaw joint

Clenching and grinding (bruxism) put parafunctional load on the chewing muscles and the joint; they can appear together with muscle pain, morning fatigue, tooth wear and sometimes joint complaints. International consensus describes bruxism as a behaviour that also occurs in healthy people — it does not cause joint problems in everyone, and not every joint problem comes from bruxism. That is why bruxism is recorded as a finding, the load is managed (a night guard, behavioural advice, sleep and stress factors), and the joint complaint is assessed separately.

Occlusion and gnathology

Occlusion (how the teeth meet) is part of the functional assessment — as a finding, not as the cause. A 2017 systematic review found no consistent cause-and-effect relationship between occlusal features and temporomandibular disorders; the approach “fix the bite and the problem goes away” therefore has no scientific basis, and irreversible treatment of the teeth is not recommended as a therapy for joint pain. The relationship between occlusion and the jaw — centric relation, vertical dimension — is taken into account in tooth wear, multiple restorations and full-mouth rehabilitation plans; in those cases functional analysis and a provisional-restoration stage become part of the plan.

Treatment options — according to the findings

• Education and self-care — soft food, avoiding wide opening and chewing gum, heat/cold, simple opening exercises; in many cases the first and sufficient step
• Load reduction — awareness of daytime clenching, habit change, attention to sleep and stress
• A splint — design and duration according to indication, under supervision
• Physiotherapy or referral to another specialist — for persistent muscle pain, a neck component, or neurological or rheumatological suspicion
• Restorative and occlusal planning — only with a clear indication (tooth wear, missing teeth, full-mouth rehabilitation); not as pain treatment
• Surgery — rarely, for specific joint conditions that do not respond to conservative treatment, together with a maxillofacial surgeon

What we do — and what we do not claim

• TMJ problems can be multifactorial; we do not pin the cause on “one thing”
• Not all clicks need treatment — a painless click is monitored
• Not all pain comes from the joint itself — muscle pain is among the most common causes
• Not every patient needs a splint; a splint does not “put the disc back”
• Not every patient needs CBCT or MRI
• Irreversible changes to the occlusion are not recommended as treatment for joint pain
• No guarantee of outcome; in chronic cases the goal is to restore function and manage pain

Duration and price

The length of treatment depends on the findings: self-care and education can take effect within a few weeks; splint therapy with review visits can continue for months; restorative plans follow their own calendar. The prices below come from the same source as the site’s Prices section; whether an appliance is needed and the overall plan are decided after the examination.

Dr. Maharram Mammadov and the gnathological approach

In our clinic the assessment and treatment of TMJ complaints are carried out by orthodontist-gnathologist Dr. Maharram Mammadov, the author of the site’s articles on the jaw joint, splints, bruxism and occlusion. The essence of the gnathological approach is to assess the joint, the muscles and the occlusion as one functional system rather than separately, and to keep intervention as minimally invasive as possible.
