Does my child need nitrous oxide (happy gas) sedation?

Children who have not had dental treatment or are anxious about dental treatment may benefit from nitrous oxide sedation. It is used to help alleviate anxiety and discomfort, and promote a positive experience during dental treatment. A child will typically wear a nose mask and breathe in a mixture of nitrous oxide and oxygen gases. During this form of sedation a child remains awake and is able to communicate with the dentist. Once dental treatment is complete the gas is turned off and the effects of nitrous oxide will wear off within minutes. Nitrous oxide is one of the most commonly used forms of sedation in paediatric dentistry and has no known adverse effects on a child’s growth and development.
