Do i need to take a course of antibiotics before root canal treatment?

Maybe: If you have a heart issue that requires antibiotics before dental procedures, then yes or if you have an associated infection that makes good anesthesia difficult, then yes, you may require a course of antibiotics. Otherwise, the chances are slim that you will need them prior to having the root canal procedure done.

It depends: On whether you have an infection, abcess, fistulous tract, etc. Your dentist or endodontist is the one best able to advise you based on your specific situation.
