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, then 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 notify us of any change in your child’s health and/or medical condition. Do not bring your child for treatment with a fever, ear infection or cold. Should your child become ill, contact us to see if it is necessary to postpone the appointment.

You must tell the doctor of any drugs that your child is currently taking and any drug reactions and/or change in medical history.

Please dress your child in loose fitting, comfortable clothing.

Please make sure that your child goes to the bathroom immediately prior to arriving at the office.

Your child should not have milk or solid food after midnight prior to the scheduled procedure and clear liquids ONLY (water, apple juice, Gatorade) for up to 6 hours prior to the appointment.

The child’s parent or legal guardian must remain at the office during the complete procedure.

After the sedation appointment:

     Your child will be drowsy and will need to be monitored very closely. Keep your child away from areas of potential harm.

If your child wants to sleep, place them on their side with their chin up. Wake your child every hour and encourage them to have something to drink in order to prevent dehydration. At first it is best to give your child sips of clear liquids to prevent nausea. The first meal should be light and easily digestible.

If your child vomits, help them bend over and turn their head to the side to insure that they do not inhale the vomit.
