What is nitrous oxide? Nitrous oxide is a popular anaesthetic agent used by dentists. Its safety has been well-established; it is effective, and the anaesthetic effect wears off quickly so there is no extended recovery time. It can be used for both children and adults. Nitrous oxide has a very calming, comforting effect, even though the patient remains in control. Some dental experts have called it the "ideal anaesthetic" because it takes effect quickly (in less than 5 minutes) and because there is a very rapid recovery time (about 5 to 10 minutes). Nitrous oxide is mixed with oxygen so that you will have an ample supply of oxygen at the same time.

In addition to the sedative effect of nitrous oxide, it helps control discomfort associated with some procedures. The level of sedation can be easily adjusted for the best possible effect for each individual patient.

The effects of nitrous oxide
Nitrous oxide kills pain and it induces a pleasurable feeling. After 5 minutes or so of breathing in the gas, you should feel a euphoric feeling spread throughout your body. It really kind of feels like a 'happy drunk' feeling. Some people find that there are auditory or visual effects as well. You will feel a bit light headed and often people get 'the giggles' (hence the name laughing gas!). As an interesting aside, nitrous oxide was one of the drugs of choice for young people in the late1700s and early 1800s, when "laughing gas demonstrations" were a popular source of entertainment and enjoyment!
