A 56-year-old woman presented with persistent unilateral gnathological complaints after replacing an amalgam restoration. The patient reported tension and pain in the right side of her jaw, along with crackling sounds in the temporomandibular joint. Physical examination revealed tenderness in the right masseter muscle and temporomandibular joint, as well as anterior disc replacement with reduction on both sides. The initial treatment focused on providing rest to the temporomandibular joint, the Yoda exercise, and later, wet-needling. Despite initially limited improvement, the symptoms persisted. This case underscores the complexity and various treatment options for temporomandibular joint issues following dental procedures.
