Inhalation sedation (happy gas)

Happy gas is a way that our Chermside Dental Care team can help you feel relaxed at the dentist. It helps take the edge off the whole appointment as you breathe through a nose-piece during your dental visit. You will feel a bit spacey, relaxed and a significant reduction in sensations. Happy gas almost makes you feel ‘tipsy’, in a way, and is a safe adjunct for any dental visit.

The treatment involves breathing in a mixture of nitrogen and oxygen (‘laughing gas’) which quickly leads to a pleasant, relaxed feeling. You remain conscious all the time, although you may be a little drowsy. There are no after-effects and you can drive a car after about 15 minutes. For all of these reasons, happy gas is the most frequently used and safest sedation method used in dentistry.

Advantages of dental inhalation sedation:

  • Safe
  • Rapid onset
  • Flexible duration can be used for any appointment length
  • Absolute control. It is easy to quickly control the level of sedation
  • People recover quickly
  • Very few side effects
  • There is an analgesic effect (pain-free)
  • You can return to normal activities immediately after the appointment


In addition to the great calming benefits, happy gas is also extremely safe as it is a combination of Nitrogen and Oxygen which are both present in the air we breathe. Happy gas never goes below 30% oxygen, of which there is 20% in normal air.

Other options:

The other alternative here at Chermside Dental Care is IV sedation.

IV sedation is a heavier form of anaesthesia where our specialist anaesthetist will help sedate you using traditional hospital setting medications. With IV sedation, your memory will be hazy for the procedure. You also can’t drive for 24hours afterwards. For more information, please visit our dedication information page on IV sedation.
