A root canal can be done in as little as 20 minutes, up to a few hours, depending on the case. Most cases typically take about an hour. Variables in the treatment time depend on the time to get you completely numb, pain free, adequately sedated (if chosen), the complexity of the case (i.e. number of canals, calcifications, curved roots, etc.), and the number of teeth treated.
Endodontics is one of the 9 specialty fields recognized by the American Dental Association’s approved Specialties of Dentistry. Each of the 9 specialties requires additional schooling beyond the 4 years required for a DDS or DMD degree. A root canal procedure is part of the endodontic training received during a 24-36 month residency program. Additional training and procedures typically provided by an endodontic practice include root canals, internal medicine, radiology, diagnosis, anesthesia, pain control, emergencies, endodontic failures/retreatment of root canals, microbiology, pathology, immunology, dental anatomy, surgery, restorative procedures, bleaching, trauma, pediatrics, and geriatrics.
The root is not taken out. A root is removed only when a tooth is pulled or extracted. During a root canal the center of the root of a tooth is cleaned out and filled with rubber like material called gutta percha. A good analogy to this would be like removing the lead out of a pencil, and filling the remaining hollow tube with plastic. By removing the center of the root (the dental pulp), the inflamed or infected tissue is removed/filled with gutta percha making the tooth comfortable again and in full function. Previous pain, swelling and infection goes away and the root canal procedure enables you to keep your original, natural tooth. The root canal procedure prevents the need for a tooth to be pulled, and subsequent missing teeth, dental bridgework, dentures, or implants.
With proper diagnosis and treatment planning, many times antibiotics and/or anti-inflammatory medicine is prescribed in advance of the root canal to minimize or completely eliminate pain. We generally recommend a separate examination prior to the root canal to properly prepare and medicate the case to maximize pain control before, during, and after the procedure. This preparation along with skillful local anesthesia techniques and post operative pain control will make your root canal a pleasant experience. Conscious sedation will also eliminate anxiety issues that patients may have from a prior pain experience. We never advance further in the procedure unless you are comfortable and pain free.
