A painkiller is a medicine that's used to dull or relieve pain, like the painkiller your dad gives you when you have a bad headache.
Painkillers are meant to do exactly what their name says: to kill pain. You can also call this kind of medication an analgesic. These range from aspirin and acetaminophen, which are sold over the counter to treat minor aches and pains, to powerful anesthetics administered by doctors before surgery. If you get your wisdom teeth removed, you'll most likely need a painkiller during and after the procedure.
