Nitrous Oxide is a sweet smelling, non irritating, colorless gas which you can breathe.
Nitrous Oxide has been the primary means of sedation in dentistry for many years. Nitrous oxide is safe; the patient receives 50-70% oxygen with no less than 30% nitrous oxide.
The patients are able to breathe on their own and remain in control of all bodily functions.
The patient may experience mild amnesia and may fall asleep not remembering all of what happened during their appointment.
Though there are no 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 and pregnant or nursing women.
