This drug causes a temporary loss of feeling, making it your best friend if the drill has to be used. The word anesthetic traces back to the Greek word anaisthēsia, from a combination of an-, meaning “without” and aisthēsis, meaning “sensation.” If you take an anesthetic that’s what happens: you are temporarily without sensation, meaning you feel no pain.
