Immediate Dental Pain and Anxiety Relief, Nitrous Oxide and Penthrox™

Nitrous Oxide and Penthrox™ are products which can be inhaled which will provide you with immediate pain relief.

At Redbank Dental Centre we offer our patients two types of pain relief – one Nitrous Oxide and the other Penthrox™ so your dental experience will be as comfortable as possible. Penthrox™ is the combination of an inhaler device and a pharmaceutical agent that has been used in Australia for over 30 years by healthcare professionals for the provision of immediate pain relief.


When used as directed, it is safe, effective and quick. Penthrox™ will provide you with strong pain relief while at the same time helping you feel more comfortable. And you are in control of the level of your relief, simply by inhaling Penthrox™ through the Penthrox™ Inhaler. Ask your dentist for Penthrox™ prior to your treatment.

Patient instructions and information…

  • Relief will commence after approximately 6 – 10 breaths.
  • Relief will persist for several minutes after ceasing use of Penthrox™.
  • The patient is in control of the level of their relief.
  • Breathe through the mouthpiece, initially ensuring that the “dilutor” hole of the AC Chamber is not covered.
  • Breathe out either through the AC Chamber attached to the Penthrox™ Inhaler or through the nose (patient preference).
  • If further relief is required, the “dilutor” hole of the AC Chamber may be covered for a higher inspired concentration of Penthrox™.

Nitrous Oxide

This is a safe and effective sedative agent and is mixed with oxygen and inhaled through a small mask. Sometimes known as ‘laughing gas’ but it does not put you to sleep. You will still be aware of your surrounding and what is happening. Some patients have a feeling of heavy arms and legs but you feel calm and relaxed. After the mask is removed the effects soon wear off but it can take up to 15 minutes to wear off completely. You can still drive after having Nitrous Oxide but you will be guided by our dental staff before leaving the practice. However Nitrous Oxide is NOT safe during pregnancy.
