Nitrous Oxide

Laughing Gas

Nitrous Oxide 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 and effective in helping to relieve the anxiety, or fear, that some patients feel about undergoing dental treatment. The patient receives 60-80% oxygen with 20-40% nitrous oxide, depending on the patient’s comfort level and the type of dental procedure.

The patient is able to breathe on their own, remains coherent and alert during the procedure, and can control body movements and respond to verbal commands and questions.

Infrequently, the patient may experience mild amnesia and may fall asleep, not remembering much of what happened during their appointment.

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 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 killing 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.
