Are you nervous to go to the dentist? At Green Square Dental we offer Happy gas to help relax you and give you a pain free, pleasant dental experience.

Nitrous is suitable for nearly all patients, young and old,healthy or not so healthy and particularly for those with mild to moderate anxiety or dental phobia.

What is it? And what does it do?

Nitrous oxide (N2O) is simply a gas which you can breath in.

It has no color, smell, and doesn’t irritate.

A small nasal inhaler is gently placed over the patient’s nose.

This is very comfortable and can be adjusted by the patient if desired.

Within 5 minutes of breathing in the gas, you should feel

a euphoric feeling spread throughout your body.

You will feel a bit lightheaded and often people get ‘the giggles’

(hence the name laughing gas!).


Nitrous oxide works very rapidly – it reaches the brain within 20 seconds, and relaxation and pain-killing properties develop after 2 or 3 minutes.The depth of sedation can be altered from moment to moment,allowing Dr Shapiro to increase or decrease the depth of sedation.

There’s no “hangover” effect – the gas is eliminated from the body within 3 to 5 minutes after the gas supply is stopped.You can safely drive home after treatment.

Happy gas is very safe. It has no side effects and it has no ill effects on the heart, lungs,liver, kidneys, or brain.
