Inappropriate use of dental equipment that is powered by highly compressed air may directly lead to the formation of subcutaneous emphysema that involves the fascial planes of the head and neck. The high-speed dental handpiece and the air and water dental syringe are the instruments that are most commonly implicated in the reported cases. The treatment of such cases requires a reassured patient, prophylactic antibiotic coverage, and close postoperative follow-up care. Patients should avoid maneuvers that could increase intraoral pressure. Complete resolution should be expected within one week.
