Comfort & Sedation

Nitrous Oxide (Laughing Gas)

Also called: laughing gas, happy gas

Nitrous oxide, commonly called laughing gas, is a mild sedative you breathe through a small mask. It takes the edge off anxiety and discomfort, then clears your system within minutes once it is turned off. It is gentle enough that most people drive themselves home.

What to expect

  • You breathe the gas through a soft nose mask during treatment.
  • You feel light and relaxed but stay fully awake and aware.
  • The effect lifts quickly, so it suits routine anxious visits.

Questions to ask a practice

  1. Is laughing gas enough for my level of anxiety?
  2. Can I drive myself home afterward?
  3. Is it safe for me or my child given our health history?
