Nitrous Oxide/Oxygen Analgesia

Nitrous oxide analgesia, also known as "laughing gas", is a blend of two gases, nitrous oxide and oxygen. Nitrous oxide has a very calming effect and the patient remains fully conscious with all natural reflexes. Patients are not "put to sleep" with the low concentrations used in our office. Nitrous oxide analgesia is very helpful for mildly anxious children during routine dental procedures and for children with a hypersensitive gag reflex when taking dental radiographs.

Nitrous oxide/oxygen is administered with a nasal mask and the patient is observed carefully by the dentist and staff through the entire procedure. At the end of the procedure the patient breathes 100% oxygen for at least five minutes and the nitrous oxide is quickly eliminated from the patient's body. Patients may resume normal activities following the procedure.

Nitrous oxide analgesia is not effective for all children, especially those with extreme anxiety and those requiring extensive dental treatment. Since each child in our practice is considered according to their individual needs, we may discuss other behavior management techniques that better suit your child.

 

Prior to your appointment with nitrous oxide analgesia:

  • Please inform us of any changes in your child's medical history.
  • Tell us about any condition that makes breathing through the nose difficult for your child.
  • Let us know if your child is taking any medication on the day of the procedure.
  • Avoid eating for two hours prior to the dental procedure.
