Informed Consent for Nitrous Oxide

Nitrous Oxide Sedation

Nitrous oxide, or “laughing gas,” is an analgesic and mild sedative. It is a very safe gas/oxygen mixture, which is inhaled nasally. The use of   nitrous oxide can help many people learn to cope with the sometimes stressful dental experience. Since nitrous oxide generally provides a pleasant sensation, it enables people to remain relaxed for their dental treatment. Nitrous oxide decreases fear, anxiety, apprehension, and pain sensations, but it does not always work for everyone.


Nitrous oxide in the dental office is never used as a general anesthetic; it does not put you “to sleep.” For this reason, local anesthetic may still be necessary, but much more comfortable to receive.


A nasal mask is placed on the nose, and the nitrous oxide gas is breathed in.


Help with anxiety and pain, gagging, and medically compromised individuals.
