Nitrous Oxide (laughing gas)

Nitrous oxide may be a useful supplement to traditional anesthesia to reduce anxiety or suppress a gag reflex.  The patient is able to breathe on their own and remain in control of all bodily functions.  Most patients are able to have dental treatment with traditional local anesthetic, but for those who are highly anxious or fearful, nitrous oxide may be  useful adjunct.

Though there are no other major contraindications to using nitrous oxide, you may not want to use it if you have emphysema, exotic chest problems, M.S., a cold or other difficulties with breathing.
