Nitrous Oxide
Some children are given nitrous oxide/oxygen, or what you may know as laughing gas, to relax them for their dental treatment. Nitrous oxide/oxygen is a blend of two gases, oxygen and nitrous oxide. Nitrous oxide/oxygen is given through a small breathing mask which is placed over the child’s nose, allowing them to relax, but without putting them to sleep. The American Academy of Pediatric Dentistry recognizes this technique as a very safe, effective technique to use for treating children’s dental needs. The gas is mild, easily taken and with normal breathing, it is quickly eliminated from the body. It is non-addictive. While inhaling nitrous oxide/oxygen, your child remains fully conscious and keeps all natural reflexes.

Prior to your appointment:
  • Please inform us of any change to your child’s health and/or medical condition.
  • Tell us about any respiratory condition that makes breathing through the nose difficult for your child. It may limit the effectiveness of the nitrous oxide/oxygen.
  • Let us know if your child is taking any medication on the day of the appointment.
  • Please do not feed your child within one hour of dental procedure.

An important point to remember is that if your child develops a fever, productive cough, and/or heavy nasal drainage within 24 hours of the appointment, please notify our office. We may need to reschedule.
