Temporomandibular joint disorder (TMD) is a painful functional disorder of the temporomandibular joint, masticatory muscles, and associated musculoskeletal structures of the head and neck. TMD is a type of chronic pain and is widely used as a model for chronic pain. The etiology of TMD pain is multifactorial. Biological, behavioral, environmental, social, emotional, and cognitive factors can contribute to TMD. TMD can manifest with musculoskeletal facial pain complaints and with different forms of jaw dysfunction. Biobehavioral studies suggest an association between TMD pain and coexisting psychopathology, including depression and anxiety. This chapter presents practical clinical recommendations on how to treat patients with symptoms of depression, anxiety, and TMD pain. The authors underline the importance of considering depression and anxiety as risk factors for TMD.
