Nitrous oxide (“laughing gas”) is a form of ‘conscious sedation’ which can help reduce dental anxiety for the nervous patient. The goal of nitrous oxide sedation is to simply reduce patient’s anxiety and apprehension so they can have a less stressful dental visit. The technique is frequently used during surgical procedures and for fearful pediatric dental patients. Nitrous oxide sedation is very safe. The nitrous oxide is mixed with oxygen and delivered to the patient through a mask that is worn on the nose. It is referred to as conscious sedation because the patient remains awake during the procedure. After this type of sedation, the patient is delivered 100% for approximately 5 minutes. They are now ready to leave the office on their own and operate a motor vehicle.
