Nitrous Oxide (laughing gas)

Nitrous Oxide is a safe sweet-smelling, non-irritating, colorless gas which you can breathe. It has been the primary means of sedation in dentistry for many years.The patient receives 50-70% oxygen with no less than 30% nitrous oxide. The patient is able to breathe on their own. The patient may experience mild amnesia and may fall asleep.

Advantages to 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.
  • In minutes you can experience the relaxing effect.

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.
