Dental surgical emphysema is a condition characterized by air being trapped within the soft tissues of the face and neck, typically occurring after dental procedures. This may happen due to the use of high-speed instruments that can generate air pressure, leading to the introduction of air into the tissues.

The presence of this trapped air can cause swelling and discomfort in the affected area, and it is essential for dental professionals to recognize and manage this condition, as it can lead to complications if not addressed adequately. Understanding this condition is important for dental nurses as it informs them about potential postoperative complications and the need for appropriate patient monitoring and care following surgical interventions.

In contrast to the other options, swelling of the gums typically refers to periodontal issues rather than emphysema, tooth enamel erosion relates to the wear of tooth surfaces rather than air presence in soft tissues, and temporary numbness in the cheeks may be related to nerve involvement during procedures but does not describe the specific condition of emphysema.
