Nitrous oxide/oxygen is a safe, effective sedative agent used to calm a child’s fear of the dental visit and enhance effective communication. It is often called “laughing gas” since it may provide a feeling of giddiness or euphoria. Additionally, nitrous oxide/oxygen works well for children whose gag reflex interferes with dental treatment.
When your child receives nitrous oxide/oxygen, a fitted mask is placed over the nose. Your child will smell a faint, sweet aroma and experience a sense of well-being and relaxation. Children sometimes report dreaming and their arms and legs may feel “tingly.” If your child is worried by the sights, sounds or sensations of dental treatment, he or she may respond more positively with the use of nitrous oxide/oxygen.
