What is Happy Gas?

Happy Gas is a form of conscious sedation that involves breathing a carefully controlled mixture of nitrous oxide and oxygen through a small nose mask during dental treatment.
Many patients report feeling calm, relaxed and less anxious while remaining awake and able to communicate throughout their appointment.
How Does Happy Gas Work?

A small mask is placed comfortably over your nose.

You breathe a mixture of oxygen and nitrous oxide.

You begin to feel more relaxed and comfortable.

Your dental treatment is completed while you remain awake.

Pure oxygen is provided at the end of treatment before you leave.

- Feel nervous about dental treatment
