Nitrous oxide, or “laughing gas,” is used as a mild sedative. It is delivered through a nose hood, and is administered throughout the entire procedure. Nitrous oxide elevates the general mood and can evoke a general sense of well-being. It relieves anxiety and reduces pain during the procedure. Some tingling and numbness may be felt. There are minimal side effects that come with nitrous oxide, and it has been safely used in dentistry for many years.
