Nitrous Oxide

Nitrous oxide, or laughing gas, is the most frequently used method for easing mild-to-moderate anxiety in children. Administered through a small mask that fits over the child’s nose, it is an effective way to calm anxiety.

Your son or daughter will be asked to breathe through the nose and not through the mouth. As the gas begins to work, your child will become calm, although he or she will still be awake and able to talk with the dentist.

At the end of the appointment, the patient will resume breathing regular oxygen, and all the effects of nitrous oxide will disappear. As your child gets older and becomes more comfortable during dental visits, nitrous oxide may not be necessary.
