Patient Information

Nitrous Oxide (laughing gas)

Nitrous Oxide has been the primary means of sedation in dentistry for many years. It can be very effective for patients who experience anxiety during dental procedures. There are many 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 once Nitrous Oxide has been stopped.
  • Inhalation sedation is safe with no side effects on your heart and lungs.
  • 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 properties develop.

Reasons to not use Nitrous Oxide

You should not utilize Nitrous Oxide if you are pregnant 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, 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.
