How it works

Your child breathes a mix of nitrous oxide and oxygen through a small nose mask. Most children feel calm within a few minutes.
Who it helps

It suits children who feel anxious, gag easily, or need a longer visit. We talk with you first and check your child's health history.
After the visit

We give pure oxygen for a few minutes at the end. The effects wear off within minutes.
Questions about laughing gas
Is laughing gas safe for children?
The American Academy of Pediatric Dentistry calls it a safe and effective way to reduce anxiety. A team member watches your child the whole time.
Will my child be asleep?
No. Your child stays awake and aware, only more relaxed.
