Nitrous oxide for kids

Nitrous oxide in dentistry, 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 your child’s nose, it is an effective way to calm anxiety.


Your little one will be asked to breathe through his or her nose and not through the mouth. As the gas begins to work, the patient will become calm, but still be awake and able to talk with the dentist.


At the end of your child’s appointment, he or she will resume breathing regular oxygen, and all the effects of dental nitrous oxide will disappear. As your youngster gets older and becomes more comfortable during dental visits, nitrous oxide may become unnecessary.
