Nitrous (Laughing Gas)
Nitrous oxide (N2O) is simply a gas which you can breathe in to relax you during treatment. It has no color, smell, and does not irritate. After 5 minutes or so of breathing in the gas, you should feel a euphoric feeling spread throughout your body. 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!).
