Happy Gas

Sometimes called laughing gas!

This practice uses happy gas to help patients feel as comfortable as possible during dental procedures.

How does happy gas work?

This gas is a combination of nitrous oxide (N2O) and oxygen (O2). Hence, the “happy” or “laughing gas” used now is called N2O-O2, and contains at least 30% oxygen. Usually, the mix is about 70% oxygen to 30% nitrous oxide.

Depending on the concentration and length of administration of the gas, the patient will experience initial light-headedness, followed by a tingling sensation, especially in the arms and legs, or a feeling of vibration (“parasthesia”), quickly followed by warm sensations, and a feeling of well-being, euphoria and/or floating. At a deeper level of sedation again, sleepiness, difficulty to keep one’s eyes open or speak (“dream”) can occur.

Happy gas helps many nervous dental patients cope with their dental procedures. The gas is administered through a mask which the patient holds over their nose.
