How does posture influence the risk of developing TMD?

• A. Posture Has No Impact On TMD Risk
• B. Poor Posture Guarantees TMD
• C. Poor Posture Can Contribute To TMD Risk
• D. Posture Completely Determines TMD Outcomes

Answer: (C)

Posture influences TMD risk because the way the head, neck, and jaw align and move affects how the jaw muscles work and how the temporomandibular joint bears load. Forward or slumped head posture shifts the mandible position and increases tension in the neck and facial muscles, which can lead to muscle fatigue, hypertonicity, and altered joint mechanics. This can raise the likelihood of pain, dysfunction, and parafunctional habits like clenching or bracing, all of which are known contributors to TMD. However, TMD is multifactorial, so poor posture does not guarantee development and does not alone determine outcomes. Good posture may help reduce baseline strain, but many people with good posture still experience TMD, and some with poor posture do not.
