What Is Nitrous Oxide Sedation?
Nitrous oxide, often called laughing gas, is a mild sedative you breathe in through a small mask that fits over your nose. It is mixed with oxygen and starts helping you feel relaxed within just a few minutes. You stay awake the whole time and can still talk with your dentist and answer questions normally. Most patients describe a warm, floaty feeling, sometimes with a light tingling in the hands or feet. Once the mask comes off, the effects fade quickly, usually within a few minutes.
