Laughing gas, officially known as nitrous oxide, is a gas that has been used for dental procedures and surgeries since the early 1800s. It is one of the oldest anesthetics still in use today. Laughing gas was first discovered by chemist Joseph Priestley in 1772. He found that when he inhaled the gas, it made him feel lightheaded and happy.
In 1845, American dentist Horace Wells became the first person to use laughing gas for a dental procedure. He used it to remove a tooth from a patient who did not feel any pain during the procedure. After this successful experiment, other dentists began using laughing gas for their own patients.
Today, laughing gas is still used for some dental procedures and surgeries. It is also sometimes used recreationally, as it can cause feelings of euphoria and relaxation. When inhaled in large amounts, laughing gas can lead to unconsciousness or even death. For this reason, it is important to be careful when using this substance and always follow safety guidelines
