Nitrous Oxide

Laughing Gas

Patient receiving nitrous oxide sedation during dental treatmentNitrous Oxide, also called laughing gas, 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, with the patient receiving 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. Some patients experience mild amnesia and may fall asleep, not remembering all of what happened during their appointment.

Advantages of Using Nitrous Oxide

  • The depth of sedation can be altered at any time to increase or decrease sedation.
  • There is no after effect such as a “hangover”.
  • Inhalation sedation is safe with no side effects on your heart and lungs, etc.
  • Inhalation sedation is very effective in minimizing gagging.
  • It works rapidly, as it reaches the brain within 20 seconds. In as little as 2-3 minutes, its relaxation and pain-relieving properties develop.

Reasons to Not Use Nitrous Oxide

You should not utilize Nitrous Oxide if you 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, exotic chest problems, M.S., a cold or other difficulties with breathing.

You may want to ask your dentist for a “5 minute trial” to see how you feel with this type of sedation method before proceeding.
