Nitrous oxide sedation ("laughing gas") has been used as the most frequent and primary means of sedation in dentistry for many years. 35% of all US dentists offer nitrous oxide sedation to help their nervous patients.

Advantages of Nitrous Oxide Sedation:

  • Works well for mild to moderate anxiety
  • Rapid Onset
  • Flexible duration can be used for any appointment length
  • Easy to quickly control the level of sedation which may be altered moment to moment 
  • People recover quickly
  • Very few side effects
  • There is an analgesic effect
  • You can drive yourself to and from your dental appointment
  • You can return to normal activities immediately

Disadvantages of Nitrous Oxide Sedation:

  • Severe anxiety may require a deeper level of sedation
  • Not recommended for people who have respiratory problems (Asthma and Emphysema)
  • Claustrophobic patients may not like the nasal mask used to administer the gas

What is Nitrous Oxide Made Of?

  • Nitrous Oxide (N2O)
  • Oxygen (O2) 

The safety features of the machine insure a patient receives no less than 30% oxygen mixed with nitrous oxide. Usually, a patient receives 50 to 70% oxygen.
