Nitrous Oxide (Laughing Gas) For Dental Treatments
Nitrous Oxide is a sweet-smelling, non-irritating, safe anesthetic without adverse effects in routine clinical use. 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 patient is able to breathe on their own and remains 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.

Nitrous oxide should not be administered to patients who recently had eye surgery that involved introducing an intraocular gas. Nitrous oxide inhalation can result in the expansion of the gas bubble in the eye causing healing complications and possibly eye damage. Due to its physical properties, nitrous oxide moves into an air space faster than air moves out, thus it may cause a gas bubble in the body to expand by up to 10%.
- Similarly, patients who recently had middle ear surgery (tympanic membrane graft) or have blocked eustachian tubes should not receive nitrous oxide sedation because the tympanic membrane can become distended and damaged following inhalation of the nitrous oxide.
- Pregnant/expecting mothers should not use nitrous oxide.
