What’s Nitrous Oxide Sedation?

Nitrous Oxide Sedation, also known as Happy Gas, involves breathing in a blend of two gases, nitrous oxide and oxygen through a mask which sits over your nose.

The Benefits:

Nitrous oxide with oxygen raises the pain threshold while giving you a feeling of well-being and relaxation. Therefore, it is often a useful solution for people who may feel nervous or anxious when undergoing a dental procedure.

How safe is it?

Very safe. Nitrous Oxide Sedation is very popular in dentistry. For many this is an ideal solution as it’s fast acting, taking only 3-5 minutes to start taking affect, while also being quickly eliminated from the body once the gas is turned off. Commonly completely eliminated within 5 minutes.  The gas can be adjusted by your dentist ensuring you are most comfortable. You will remain fully conscious throughout and can respond to questions or requests.

Is Nitrous Oxide Sedation appropriate for you?
