Nitrous oxide
Nitrous oxide, often called "happy gas", is breathed through a small, soft mask over your nose. You stay awake and can talk to your dentist throughout. It works quickly and wears off soon after the mask is removed; Victoria's Better Health Channel says it takes effect within a few minutes.
Often used for- Mild or moderate nerves
- Shorter and routine appointments
- People who may need to drive later (your dentist will advise)
- Adults and children, after a health check
