Post-Op Instructions
for Nitrous Oxide Sedation

Nitrous oxide, also known as “Laughing Gas”, is a mild sedative used to help children relax during dental procedures. It wears off quickly after the procedure, but the following aftercare steps will ensure a smooth recovery.

1. Recovery from Nitrous Oxide

  • Effects wear off within 5–10 minutes after the mask is removed.
  • Your child may feel slightly dizzy, lightheaded, or tired for a short time.
  • Let them sit in the dental chair for a few minutes before standing up to avoid dizziness.
  • Some children may feel a little nauseous, but this should pass quickly.

2. Eating & Drinking

  • If your child ate before the procedure, they can resume normal eating and drinking immediately.
  • If they had an empty stomach, start with small sips of water before eating a light meal.
  • Avoid heavy, greasy, or spicy foods for a few hours if nausea occurs.

3. Activity Restrictions

  • Most children can return to school and normal activities right away.
  • If your child still feels drowsy or lightheaded, allow them to rest until they feel normal.
  • Avoid intense physical activity (running, jumping, or rough play) for a few hours if they feel tired.

4. Oral Hygiene

  • Follow any specific instructions based on the dental procedure (e.g., fillings, extractions).
  • If no additional procedures were done, your child can brush and floss as usual.

5. When to Call the Dentist

Contact the dentist if your child experiences:
Persistent nausea or vomiting (lasting more than a few hours)
Severe dizziness, confusion, or difficulty walking
Unusual breathing difficulties (very rare)

Nitrous oxide is a safe and gentle sedation method that wears off quickly. If you have any concerns, feel free to reach out to your dentist! 😊
