From the Guidelines
Yes, TMJ disorders can cause fatigue, as the chronic pain and muscle tension associated with these disorders can lead to physical exhaustion, disrupted sleep patterns, and depleted energy levels. Temporomandibular joint (TMJ) disorders often result in chronic pain and muscle tension in the jaw, face, and neck, which can be physically exhausting for the body 1. The constant pain and discomfort can disrupt sleep patterns, leading to poor quality rest and resulting fatigue. Additionally, many people with TMJ disorders unconsciously clench or grind their teeth (bruxism), particularly during sleep, which further contributes to muscle fatigue and overall tiredness.
Some key points to consider in the management of TMJ disorders and related fatigue include:
- The prevalence of chronic TMD pain ranges from 6% to 9% in the general population, and psychological comorbidities are common 1
- Up to 30% of acute TMD may become chronic (≥3 months in duration), and women are more likely to be affected than men 1
- The connection between TMJ disorders and fatigue highlights how chronic pain conditions can have widespread effects beyond their primary symptoms
- TMJ-related fatigue often improves with proper treatment of the underlying disorder, which may include using a night guard, physical therapy, stress management techniques, and addressing any sleep disturbances.
The lack of a widely accepted, standard test to diagnose TMJ disorders, as acknowledged by the US National Institutes of Health in 2017, can make it challenging to diagnose and manage these conditions effectively 1. However, a comprehensive treatment approach that addresses the physical and psychological aspects of TMJ disorders can help alleviate fatigue and improve overall quality of life.
From the Research
TMJ Disorders and Fatigue
- There is no direct evidence in the provided studies that TMJ disorders cause fatigue 2, 3, 4, 5, 6.
- However, some studies suggest that TMJ disorders can be associated with other conditions that may contribute to fatigue, such as anxiety and depression 4.
- A study found that patients with TMJ dysfunction are at a higher risk of developing anxiety and depression, which can lead to fatigue 4.
- Another study discussed the treatment of TMJ disorders, including exercise therapy and occlusal splint therapy, but did not mention fatigue as a symptom or consequence of TMJ disorders 5.
- A review of current concepts in the aetiology, diagnosis, and management of TMJ disorders also did not mention fatigue as a related condition 6.
Associated Conditions
- Anxiety and depression are common comorbid conditions with TMJ disorders, and can contribute to fatigue 4.
- TMJ disorders can also be associated with other musculoskeletal conditions, such as myofacial pain, which can lead to fatigue 4, 5.
- The biopsychosocial and multifactorial pathophysiology of TMJ disorders suggests that various factors, including peripheral and central mechanisms, can contribute to the development of associated conditions like fatigue 6.
