    • Children’s Sedation

    • Inhalation Sedation (Happy Air) for Children.

    • Inhalation sedation is used in dental treatment to alleviate dental anxiety in children. It involves breathing in a special ‘happy air’ (nitrous oxide and oxygen) through a small nose piece. This quickly leads to a pleasant, relaxed floating feeling, much like day dreaming. It also works to make dental treatment more comfortable. Nitrous oxide works immediately once it has been inhaled. The effects of nitrous oxide last for only one to two minutes after the mask has been removed.

    • After the treatment.

      • Once treatment is over and “happy air” is stopped, most children feel back to normal within 5-10 minutes. Your child may feel a little tired however- so you should supervise any activities following the visit. If they are feeling tired, have your child rest at home and avoid letting them do any physical activity for the rest of the day.
      • The dentist may also have used a local anaesthetic during the treatment. Your child’s cheeks, lips and tongue may remain numb for up to 4 hours afterwards. It is important to continue to remind your child not to chew the cheeks, lips or tongue during this time.


    • Ongoing care.

    • Inhalation sedation is usually used for a short time to help your child get used to dental treatment. When your child has completed their course of dental treatment, they will resume to regular check-ups without the inhalation sedation.
