Nitrous oxide, commonly known as laughing gas, is a popular method to alleviate mild to moderate anxiety in children during dental visits. Delivered via a small nose mask, it helps soothe and relax anxious young patients. While under its effects, your child remains awake, responsive, and can communicate with the dentist.
Once the procedure is over and your child breathes regular oxygen, the effects of the gas vanish quickly. As children grow and become more accustomed to dental appointments, the need for nitrous oxide may decrease.
