Accidental aspiration or ingestion can occur in dental treatment, as most procedures are performed with the patient in a supine position or semi‐recumbent position. Aspiration of foreign bodies commonly causes acute symptoms such as violent coughing, choking, and dyspnea; however, if foreign bodies are stuck distally to the lower lobe bronchi or the bronchus intermedius, acute presentation can be rare. This clinical report documents a 68‐year‐old male patient who accidentally aspirated an all‐zirconia crown during the try‐in procedure. The case was initially surmised as ingestion. The crown remained in the lower lobe of the left lung for about 2 years without any significant symptoms. This report cautions the importance of airway protection during dental procedures.
