Nitrous Oxide Sedation at Valencia Dental Office
Nitrous oxide, often called laughing gas, is mixed with oxygen and inhaled through a small nasal mask. It can help patients feel calmer during dental treatment and is commonly used because the effect begins quickly and wears off rapidly after the gas is stopped.
Because the effect wears off rapidly once the gas is stopped, many patients are comfortable driving themselves home after their appointment.
