Which statement about treating temporomandibular disorder (TMD) without a diagnosis is correct?

• A. True
• B. False
• C. Not enough information
• D. Only with patient consent

Answer: (B)

Diagnosing TMD before treatment is essential because jaw pain and dysfunction can arise from many different conditions that mimic TMD. Without a clear diagnosis, starting TMD-specific therapies may mask or delay underlying problems, expose the patient to unnecessary or inappropriate treatments, and fail to address what truly needs care.

A proper evaluation involves a thorough history of the pain, functional limits, and contributing factors (like parafunctional habits or trauma) plus a focused exam of the jaw joints and masticatory muscles, assessment of range of motion, joint sounds, and facial tenderness. Imaging or referral is considered if the presentation is unclear or red flags appear. Only after narrowing to a probable diagnosis should conservative, evidence-based TMD management begin, while continuously reassessing. Consent for treatment is important, but it does not replace the need for an accurate diagnosis.
