Nitrous Oxide is a sweet-smelling, non-irritating, colorless gas which you can breathe. It has been the primary means of light sedation in dentistry for many years. Nitrous oxide is safe. The patient receives 50-70% oxygen with no less than 30% nitrous oxide. The patient is 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.
You should not utilize Nitrous Oxide if you have asthma or have been diagnosed with chronic obstructive pulmonary disease (COPD). Though there are no other major contraindications to using nitrous oxide. You may not want to use it if you have emphysema, chest problems, M.S. , a cold or other difficulties with breathing.
