Pan Killers: Most people wonder about Novacaine however this name covers many drugs(mepivacaine,marcaine....) the 'caines'. They all do the same thing...block pain to the tooth in question for 1.5 to 3.0 hours generally. They are all generally safe so do not worry and consult your dentist for any other questions you may have.
