Ludwig's angina is one of the emergency cases associated with impending upper airway obstruction. Through this case report, the neglected case of emergency medical diagnosis could be prevented and it will become a piece of evidence for the great importance of collaboration among clinicians. A 17-year old boy admitted to the emergency setting of a rural public hospital, East Belitung, Indonesia with major complaints of progressively swallowing difficulty and breathlessness with fever and chills for two weeks before hospital admission. There was a history of dental caries in mandibular right second molar.
