Temporomandibular Disorders (TMD) body chart — Illustrative, not diagnostic. Canva body chart for Temporomandibular Disorders (TMD).

Common, mostly self-limiting, and full of things students do that don't help.

Illness script in one line: ache around the jaw, temple or in front of the ear, usually one side, with clicking or catching on opening and chewing, worse with stress, clenching and long conversations, eased by rest and soft food.

Caseload frequency: high, and mostly arriving attached to something else — neck pain, headache, or a dentist's referral. Read further: global prevalence [1][2].

Start with the name

"TMJ dysfunction" is the old label. The current classification is the Diagnostic Criteria for Temporomandibular Disorders — DC/TMD [3], with the taxonomy expanded since [4] and the question of a consensus standard of care revisited [5].

Why it matters to you: DC/TMD splits this into two families that are managed differently.

	Pain-related TMD	Intra-articular TMD
Examples	Myalgia · arthralgia · headache attributed to TMD	Disc displacement with or without reduction · degenerative joint disease
Dominant complaint	Pain	Clicking, catching, locking, limitation
Your job	Load management, exercise, stress and sleep	The same, plus knowing when it's a locked jaw

Most of what you see is pain-related, most of it settles, and most of the harm comes from over-treating the noise.

2 · SE — THE SUBJECTIVE PATTERN (the 70%)

MAIN PROBLEM

"My jaw clicks and aches." Or: it catches · it locks · it's tired by the end of the day · it hurts to eat a burger.

Ask which bothers them more — the pain or the noise. The answer sorts the whole session.

BODY CHART

Pre-auricular, over the joint, into the masseter and temporalis. Usually unilateral.
± ear symptoms — fullness, ache, tinnitus. Common. Often seen an ENT first.
± temporal headache. Headache attributed to TMD is a DC/TMD diagnosis in its own right.
± neck. Cervical and postural dysfunction are common.

BEHAVIOUR

Aggs: chewing (especially tough or chewy food), long conversations, yawning, singing, dental appointments, stress. The end of a busy day.
Eases: rest, soft diet, heat, not talking.
24-hr pattern: the end of a busy day of talking and chewing. Morning symptoms point at nocturnal clenching — the bruxism referral in §6.
Night: waking with it points at clenching. Night pain with weight loss or a cancer history is the §4 flag.
Severity: VAS 0–10 at best / at worst / right now.
Coding: typically In, occasionally Is with an acute limitation. Morning symptoms point at nocturnal clenching.
Irritability: usually low.

HISTORY — five questions, three of them new

Clicking: painful or painless? And can they open fully? A painless click in someone who opens normally is common and is not a disorder.
Has the jaw ever LOCKED — and did it unlock? Closed lock that won't release is a different, urgent problem.
Sleep. It's a lever too. Read further: insomnia as a risk factor for TMD [6].
Stress and psychological load. It's worse with stress. Co-managing psychosocial stress has its evidence. Read further: psychological factors and TMD [7].
Bruxism — and hold it lightly. Read further: bruxism, TMD and headache [8][9]. The correlation is real. The causation is not settled. Don't build the whole plan on it.

And ask about headache, because the traffic goes both ways

Read further: TMD in migraine and tension-type headache [10]. Examine the jaw in your headache patients and ask about headache in your jaw patients. Every time.

SPECIAL / SCREENING QUESTIONS

Fever, swelling, trismus. Progressive limitation. Systemic joint symptoms. Numbness in the jaw or lip. Weight loss. Cancer history. New jaw pain on chewing in someone over 50. Chest, arm or jaw pain on exertion.

3 · HYPOTHESIS RANKING

Top three, and the one feature that separates each

Pattern	The discriminating feature
1. Pain-related TMD (myalgia / arthralgia)	Pain on chewing and on palpation of masseter and temporalis, reproduced by loading the jaw. Opening may be near-normal.
2. Intra-articular TMD (disc displacement)	Clicking with deviation on opening, or catching and locking. Clinical pearl: click + deviation = disc displacement with reduction.
3. Headache attributed to TMD, or a primary headache with TMD	Systematically reviewed and meta-analysed together. Which came first is usually undecidable — treat both.

Also on the list

Pattern	The discriminating feature
Cervicogenic headache / upper cervical referral	Reproduced from the upper cervical segments, not from jaw loading.
Dental pathology	Tooth-specific, thermal sensitivity, worse at night. Refer.
Ear pathology	Hearing change, discharge, vertigo. Refer.
Trigeminal neuralgia	Electric-shock paroxysms of seconds, triggered by light touch.
Giant cell arteritis	Over 50, new jaw pain on chewing, temporal tenderness, visual symptoms. See below.
Referred cardiac pain	Jaw or throat discomfort on exertion, easing with rest. Its own page.

4 · RED FLAGS — DON'T MISS THIS

Free forever. Safety is never behind a paywall.

Jaw pain has two mimics that a physiotherapy student will meet and can miss.

Finding	What it means
Over 50, NEW jaw pain that comes on with chewing and eases when they stop, with temporal tenderness, scalp tenderness, headache or visual symptoms	GIANT CELL ARTERITIS. Jaw claudication is a classification criterion [11]. Sight-threatening. SAME-DAY medical review.
Jaw, throat or neck discomfort brought on by EXERTION and relieved by rest	Cardiac referral. Its own page. Escalate.
Fever, swelling, hot joint, unable to open	Infection. Urgent.
A locked jaw that will not unlock	Acute closed lock. Urgent dental or maxillofacial review — not a mobilisation problem.
Progressive limitation with other joints involved, morning stiffness over 30 minutes	Inflammatory arthropathy. Medical review.
Numbness in the lip, chin or jaw, or a neuropathic facial pain that keeps progressing	Malignancy until excluded — cancer can present as a progressive neuropathic pain (Zakrzewska 2013) [21]. Urgent.
Unexplained weight loss, cancer history, night pain	Urgent.

The distinction that matters most

TMD jaw pain builds with chewing and lingers. Jaw claudication in giant cell arteritis comes on with chewing, forces them to stop, and eases within minutes of stopping — like claudication anywhere else. In anyone over 50, that difference is sight-threatening.

Any red flag: stop, escalate, and check it with your educator.

Guideline anchor

No Australian guideline.

The diagnostic anchor is the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) for clinical and research applications (Schiffman et al. 2014, PMID 24482784), with the taxonomy expanded (Peck et al. 2014, PMID 24443898) and the question of a consensus standard of care revisited (Manfredini et al. 2026, PMID 41065623). The physiotherapy anchor is a systematic review and meta-analysis of manual therapy and therapeutic exercise for temporomandibular disorders in Physical Therapy (Armijo-Olivo et al. 2016, PMID 26294683). The occlusion anchor is a Cochrane review of occlusal interventions (Singh et al. 2024, PMID 39282765) and a systematic review of association studies between TMD and dental occlusion (Manfredini et al. 2017, PMID 28600812).

The DC/TMD is a diagnostic classification, not a management guideline. No physiotherapy management guideline for TMD exists.
