In reality the process of completing root canal treatment ~ or dental treatment in general~ should never hurt.  Through local anesthetics your tooth should be profoundly numb and have no feeling during the procedure.  Our level of quality care for our patients is through the roof!  We treat EVERY patient as we would our own family member or special friend.  At any time you have pain or discomfort LET US KNOW!  Remember we are taking care of you, and NEVER want you to feel pain or discomfort!
