Relative analgesia (Happy gas)
Happy gas, or nitrous oxide, is a colourless, odourless gas that can provide temporary and reversible ‘sedation’ and comfort. For patients who require more anxiety busting techniques than just a calm environment and local anaesthetic, happy gas is a safe and reliable way to overcome fear.
Relative analgesia (Happy gas)
Happy gas, or nitrous oxide, is a colourless, odourless gas that can provide temporary and reversible ‘sedation’ and comfort. For patients who require more anxiety busting techniques than just a calm environment and local anaesthetic, happy gas is a safe and reliable way to overcome fear.
Nitrous oxide (N2O), more commonly referred to as happy gas, is used as a local sedation method. Nitrous oxide is effective as a sedative because it relaxes patients with the pleasurable feelings it emits. Nitrous oxide’s usefulness also stems from how quickly it works and that its effects are reversible. For those and other reasons, nitrous oxide is widely considered to be a safe sedation method.
We have Happy gas plumbed directly into each surgery, and our team is trained well as to how to use it. Normally, a mix of N2O and oxygen is given in about a one to one ratio. Some patients need more, some much less. The effects of the happy gas are ‘a feeling of calmness and happiness’ as well as a reduction in anxiety. Some funnier side effects are laughing and giggling, as well as hearing echoes of the dentists and nurses voices.

Side Effects that are unwanted can be nausea and fatigue, but these are very rare and are reversible.
Once the nitrous oxide has been turned off, a patient needs to receive oxygen for at least five minutes to avoid a headache. The oxygen purges any remaining gas from the lungs while aiding the patient in becoming alert and awake.
Meals are another focus point when receiving nitrous oxide. It’s a good idea to eat lightly prior to your procedure and avoid a big meal for three hours afterward. Also, consult your dentist as to when it is safe for you to drive post procedure.
Nitrous Oxide for Children
Happy gas is preferred in children over a general anaesthesia due to its safety. Some kids have difficulty wearing the mask , but usually it is a very well accepted treatment in children.
