What dental issue can contribute to TMD?

Explanation:
Missing teeth can contribute to TMD because losing teeth disrupts how the bite is organized and how the jaw moves. When posterior support is lost, the bite can collapse or shift, changing the way the mandible closes. This forces the jaw to adapt to a new position, altering the load on the temporomandibular joint and changing muscle activity in the masticatory system. Over time, the abnormal bite and muscle overuse can lead to pain, fatigue, and reduced jaw function, which are hallmark features of TMD. While other factors like grinding or misalignment can also play a role, tooth loss directly destabilizes occlusion and vertical dimension, making it a clear contributor to TMD.
