Anesthesia is a drug that numbs part of your body or makes you unconscious so that you don't experience pain during a procedure like surgery. Anesthesia, pronounced an-es-THEE-zhuh, comes from the Greek word anaisthetos, meaning without sensation.. There are two kinds of anesthesia: local anesthesia numbs just part of your body, like when a dentist numbs your mouth before filling a cavity.
