Nitrous Oxide (laughing gas)


Nitrous Oxide has been the primary means of sedation in dentistry for many years. Nitrous oxide is a safe, sweet smelling, non-irritating, colorless gas which the patient breathes in at an approximate rate of 50-70% oxygen and 30% nitrous oxide.

The patient may experience slight tingling in their hands and feet and a calm, relaxed feeling through out their body.

There are many advantages to using Nitrous Oxide

  • Helps eliminate patient’s anxiety.
  • Inhalation sedation is safe with no side effects.
  • It works rapidly, as it reaches the brain within 20 seconds. In as little as 2-3 minutes, its relaxation 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, respiratory problems, M.S., asthma, or other difficulties with breathing.
