Which of the following is a common use of dinitrogen(I) oxide?

Explanation

Dinitrogen oxide, also called nitrous oxide or laughing gas, is used in dentistry and surgery as a mild anesthetic. It reduces pain and anxiety during medical procedures.

The gas is safe when properly administered and wears off quickly after treatment ends. Patients remain conscious but feel relaxed and less sensitive to pain.

Nitrous oxide gets its nickname “laughing gas” because it sometimes makes people feel euphoric. Dentists commonly mix it with oxygen for safe patient sedation.
