If you’ve been treating recurring headaches for months without lasting relief, and you also notice jaw soreness, clicking, or morning tooth aches, the two may be connected. Temporomandibular disorders (TMD) — problems affecting the jaw joint and chewing muscles — are a recognized cause of head and face pain, and headache is one of their most common associated complaints.
Key Points
- Headache is a well-documented comorbidity of TMD, alongside neck pain, joint pain, and low back pain.
- TMD affects an estimated 5–12% of the general population, most often between ages 16 and 40, and more often in women.
- “Headache attributed to TMD” is a specific diagnostic category — separate from migraine or classic tension-type headache — defined by pain reproduced on jaw muscle palpation or movement.
- The likely mechanism in muscle-based cases is prolonged jaw muscle contraction and fatigue, though this pathway is not fully proven.
- Diagnosis relies on clinical examination criteria, not imaging alone.
What’s the Connection Between the Jaw and Headaches?
The muscles that close and move your jaw — the masseter and temporalis — sit directly over the sides of your skull and temples. When these muscles are overworked, commonly from clenching or grinding (bruxism), they can develop myalgia: tenderness and pain on use or palpation. Because the temporalis muscle overlies the temple region, pain generated there can be felt as, or contribute to, a headache.
This is distinct from a coincidence of two unrelated problems. Clinical diagnostic criteria (Schiffman et al., 2014) formally recognize headache attributed to TMD as a category: a headache that is reproduced or aggravated when the examiner palpates the masseter or temporalis muscles, or when the patient moves their jaw. This reproducibility is what separates a jaw-related headache from a primary headache disorder like migraine.
Chronic jaw muscle pain and tension-type headache also share overlapping features. Both are thought to involve sustained muscle contraction and fatigue, and both are associated with stress, anxiety, and depression. The exact biological mechanism linking prolonged muscle contraction to pain is still not definitively proven, but the clinical pattern — pain that builds with stress or jaw use and improves with muscle rest — is well established.
Research on TMD comorbidities consistently finds that headache (both migraine and tension-type), neck pain, other joint pain, and low back pain occur together with TMD more often than would be expected by chance. This doesn’t mean TMD causes every headache a patient has, but it does mean the jaw should be evaluated as a possible contributing source when standard headache treatment isn’t working.
How Is It Diagnosed?
There is no single test that confirms a jaw-related headache. Diagnosis is clinical and follows a structured process:
- History — headache pattern, timing (especially morning headaches or teeth that ache on waking, which suggest nighttime clenching), and any relationship to chewing or jaw movement.
- Palpation of masticatory muscles — the examiner presses on the masseter, temporalis, and related muscles. Reproducing the patient’s usual headache pain supports a diagnosis of TMD-related myalgia and headache attributed to TMD.
- Jaw movement assessment — range of motion, deviation, and pain during opening, protrusion, and lateral movement help distinguish muscle-based (myogenous) TMD from joint-based (disc displacement) causes.
- Ruling out joint pathology — the absence of joint sounds, joint pain, or a fixed deviation in opening pattern points away from a disc displacement and toward a muscular cause, which is more likely to present with headache.
- Screening for bruxism — clenching or grinding, whether awake or during sleep, is a common driver of the muscle overload that produces both jaw pain and associated headache.
| Feature | Headache Attributed to TMD | Primary Tension-Type Headache | TMJ Disc Displacement |
|---|---|---|---|
| Pain reproduced by jaw muscle palpation | Yes | No | Not typically |
| Jaw clicking, popping, or locking | Sometimes | No | Common |
| Morning headache or tooth soreness | Common (suggests nocturnal clenching) | Less specific | Less specific |
| Limited or deviated jaw opening | Possible if muscular | No | Common |
| Associated with stress, anxiety, depression | Frequently reported | Frequently reported | Less directly linked |
Which Treatment Is Right for Me?
Treatment decisions follow the diagnosis, not the symptom in isolation. Since acute and chronic pain are managed differently, the first distinction a clinician makes is how long the pain has been present and whether an identifiable trigger (like a recent increase in clenching) is still active.
| Approach | What it addresses | Typical candidate |
|---|---|---|
| Behavioral/habit modification | Clenching, grinding, jaw bracing | Patients with clear parafunctional habits and recent-onset symptoms |
| Occlusal splint (night guard) | Reduces load on jaw muscles during sleep | Patients with morning headache, tooth soreness, or sleep bruxism |
| Physical therapy / muscle-directed care | Muscle fatigue, myofascial tightness | Chronic myalgia without joint pathology |
| Stress/psychological management | Contribution of stress, anxiety, depression to muscle tension | Chronic cases where a psychogenic component is identified |
| Referral for joint-specific evaluation | Disc displacement, joint noise, locking | Cases with mechanical joint findings rather than muscle findings |
For chronic muscle-based pain, treatment is more layered because the original trigger is often no longer the main driver of the pain by the time a patient seeks care. Management typically combines habit and load reduction with a strategy for any contributing psychological or stress-related factors, rather than a single fix.
When to Get Evaluated
If headaches persist despite typical medical headache management, and you also notice jaw soreness, clicking, morning tooth pain, or limited jaw opening, an orofacial pain evaluation can determine whether TMD is a contributing factor. This is particularly relevant if standard headache treatment has not resolved symptoms after a reasonable trial. Patients in the Canoga Park, Chatsworth, and Northridge area can be evaluated by a clinician with specific training in temporomandibular disorders and orofacial pain to determine whether jaw-directed treatment is appropriate alongside existing headache care.
For Referring Providers
Consider TMD in the differential for patients with headache refractory to standard therapy, particularly when history includes morning headache, awakening tooth pain, or reported clenching/grinding. Diagnostic Criteria for TMD (DC/TMD; Schiffman & Ohrbach, 2016) provide a validated exam protocol, with masseter/temporalis palpation reproducing the patient’s headache as the key finding supporting “headache attributed to TMD.” Note the higher comorbidity of TMD with migraine, tension-type headache, neck pain, and low back pain reported in the literature — a positive finding on one axis warrants screening for the others. Absence of joint sounds, joint pain, or fixed opening deviation favors a myogenous rather than intracapsular process and should guide referral toward muscle-directed management versus joint-specific workup.
