Facial pain and TMD
Differentiate dental pain, muscular or joint pain, neuropathic pain and headache. Avoid irreversible occlusal treatment without a clear diagnosis.
Understand
TMD, myofascial pain, dental disease, neuralgia and other neuropathic or headache disorders can refer pain to similar sites. Diagnosis precedes treatment.
Assess
Map the pain, triggers, duration, joint noises, opening, muscle tenderness and neurological findings. Consider red flags such as progressive sensory loss or a new persistent mass.
Apply
Start with reversible measures for likely TMD and review response. Avoid irreversible occlusal adjustment or repeated dental treatment when the source is uncertain.
Key distinctions
Myofascial TMD usually has reproducible muscle tenderness and functional associations, while neuropathic pain may be electric, burning or accompanied by sensory change. Headache and dental pain may coexist. The goal is a positive diagnosis with a plausible mechanism, not just exclusion of every tooth. Reversible self-management, physiotherapy or appliances are considered case by case, with review of response.
Think through a case
A patient has bilateral masseter tenderness and morning ache, but also progressive unilateral numbness. The neurological feature prevents a simple TMD-only conclusion.
The distinction to remember
Do not perform irreversible occlusal treatment for a symptom pattern that has not been adequately diagnosed.
Test your recall
Why ask about paraesthesia in facial pain?
Show answer
Altered sensation may suggest a neurological or structural cause.
