What Our Patients Are Saying!


Aside from being an undeserving synonym for pain and discomfort, root canals are somewhat of a mystery to most patients. Few, if any, know even the basic purpose of having a root canal and most patients don’t know and don’t consider what the various root canal treatment stages consist of. Endodontic therapy serves a very deliberate purpose and generally has very predictable treatment stages and outcomes. In order to better understand what a root canal is and why it is performed, it is helpful to examine the procedure step by step.
