Nitrous oxide – a gentle sedation method!

By med. dent. Andrea Zimmermann

A visit to the dentist can be a stressful experience—especially for anxious children. Thanks to our many years of experience in pediatric dentistry in Zurich, we know the best ways to help children feel at ease and safe. However, there are situations where even the most empathetic approach is not enough—whether a child has intense fear of treatment or simply cannot stay still for long enough. In such cases, nitrous oxide can be a valuable support. But what exactly is nitrous oxide, and how is it used in pediatric dentistry?

What is nitrous oxide?

Nitrous oxide (chemical formula N₂O), also known as laughing gas, is a colorless and odorless gas that has been used for many years in dentistry as a form of sedation. It has a calming effect, reduces pain perception, and gently alleviates anxiety. Throughout the procedure, the child remains awake and responsive, which makes this a particularly safe method.

How is it administered?

The child inhales the nitrous oxide through a nasal mask, which delivers a mixture of oxygen and nitrous oxide. Within just a few breaths, the calming effect begins to take hold. The child often feels light and carefree; some even report a pleasant tingling sensation or a feeling of weightlessness.

Throughout the entire treatment, the dosage is individually adjusted to ensure optimal effectiveness. After the procedure, the child breathes pure oxygen for a few minutes, which quickly clears the nitrous oxide from their system. Shortly after the treatment, the child is fully alert and ready to continue their day.

Benefits of Nitrous Oxide for Children

• Reduced anxiety: Children feel less fear and tension during treatment.
• Safe administration: The method is easily controlled and takes effect quickly.
• Short recovery time: Nitrous oxide is quickly eliminated from the body.
• Pain reduction: Children perceive pain less intensely.
• Improved cooperation: Especially helpful for very anxious or restless children, nitrous oxide makes treatment easier

Is nitrous oxide suitable for every child?

Nitrous oxide is a very safe and effective method for most children. However, there are a few exceptions—for example, if the child has a blocked nose or certain respiratory conditions. Before the treatment, we will discuss with you whether nitrous oxide is the right option for your child.

Conclusion

Nitrous oxide is a proven and gentle method to help children overcome their fear of dental treatment. It creates a relaxed atmosphere and makes the dental visit easier for both young patients and their parents.
