Laughing gas, also known as nitrous oxide, is a colorless, non-flammable gas that has been used as an anesthetic and pain reliever since the 1800s. It is commonly used in dentistry, particularly for procedures involving wisdom teeth extraction.
When inhaled, laughing gas produces a sense of relaxation and euphoria, which can help to relieve anxiety and pain. It also has mild sedative effects, which can make patients more comfortable during dental procedures. Laughing gas is typically administered through a mask that fits over the nose and mouth. The effects of the gas wear off quickly once the mask is removed.
