The human larynx is a complex organ, playing a major role in the protection of the lower airway; It's unusual for a foreign body to be inhaled rather than swallowed and when it happens constitutes a real life-threatening emergency. We present a case of a middle age female with a 13-month history of stridor and dyspnea, managed and treated as an asthma patient. After the airway was secured a direct microlaryngoscopy was performed removing the obstruction resulting to be a dental prostheses 50 mm long. This kind of pathology has to be suspected and correctly diagnosed and treated to prevent further complications.
