Nitrous oxide, or laughing gas, is the most frequently used method for easing mild to moderate anxiety. Administered through a small mask that fits over your nose, it is an effective way to calm anxiety, raise your pain threshold, and even make time seem like it's passing quicker than usual. As the oxygen and nitrous oxide gases begin to work, you will become more calm, although you will still be awake and respond to questions.
At the end of your appointment you will be able to drive home on your own and you can resume normal activities immediately.
