Nitrous Oxide (also called laughing gas). This gas, which is
inhaled by the patient through a rubber face mask, helps people feel relaxed
and is one of the most common forms of sedation used in the dental office.
Effects wear off quickly after the gas is turned off.
This is the only form of sedation under which patients can drive
after the procedure and can eat food within a 12-hour period of the procedure.
With IV, oral and general anesthesia, the patient cannot drive following the
procedure or eat after midnight the night before the procedure.
