What is nitrous oxide/oxygen?
Nitrous oxide/oxygen is a blend of two gases-oxygen and nitrous oxide. A fitted mask is placed over the nose and, as the patient breathes normally, uptake occurs through the lungs. At the end of treatment, it is eliminated after a short period of breathing oxygen and has no lingering effects.
How safe is nitrous oxide/oxygen?
Very safe. Nitrous oxide/oxygen is perhaps the safest sedative in dentistry. It is well tolerated. It has a rapid onset, is reversible, can be adjusted in various concentrations and is non-allergenic. Your child remains fully conscious -keeps all natural reflexes- when breathing nitrous oxide/oxygen. He/she will be capable of responding to a question or request. Nitrous oxide/oxygen may also be used in combination with other sedative agents.
