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 your child’s nose, it is an effective way to calm anxiety. Your child will be asked to breathe through his or her nose and not through their 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 your child’s appointment, he or she will be breath 100% oxygen, and all the effects of nitrous oxide will disappear. Depending on the treatment rendered, most patients can resume their normal daily activities after their dental visits.
