Hook pain may be a manifestation of temporomandibular joint disorder, often caused by overloading of the joint, disorders of occlusal relationship and bad habits, etc. It is recommended to correct the cause of the disease in time and go to the hospital for specific examination and treatment. The presence of missing teeth on one side, prolonged partial chewing, and frequent eating of hard food may cause increased pressure in the joint on one side, and pain may occur due to overloading. Early contact at the tips of the teeth, occlusal interference, or excessive wear of the teeth may result in occlusal trauma, affecting the temporomandibular joint and causing hook pain. Prolonged compression of the temporomandibular joint or frequent hand propping of the jaw, etc., may be symptomatic. It is recommended to correct bad habits such as sideways chewing and hand propping of the jaw, to remove occlusal interference and to restore missing teeth in a timely manner.
