What is the relationship between posture and TMJ disorders?

Poor posture can significantly contribute to TMJ disorders by affecting the alignment and mechanics of the head, neck, and jaw. When a person has poor posture, particularly in the cervical spine and upper back, it can lead to muscular imbalances and tension. This tension often manifests in the jaw muscles, particularly the masseter and temporalis, which can exacerbate symptoms associated with TMJ disorders, such as pain, tension, and limited jaw movement.

Additionally, postural issues can alter the position of the mandible, which may lead to improper joint function and increase the stress on the temporomandibular joint itself. Therefore, maintaining good posture is essential, as it helps ensure that the jaw's mechanics are functioning optimally, potentially alleviating some symptoms related to TMJ disorders.

The idea that good posture eliminates TMJ disorders is overly simplistic, as several other factors contribute to these conditions. Similarly, the notion that posture has no effect on TMJ disorders ignores the well-documented link between musculoskeletal health and joint function. Finally, stating that poor posture affects only neck pain is an incomplete view, as it overlooks the broader implications poor alignment can have on the entire musculoskeletal system, including the jaw and TMJ function.
