Occasionally, a nonsurgical root canal procedure alone cannot save your tooth and your endodontist will recommend surgery. Endodontic surgery can be used to locate small fractures or hidden canals that weren’t detected on x-rays or during previous treatment.
Traumatic dental injuries often occur in accidents or sports-related injuries. Chipped teeth account for the majority of all dental injuries. Dislodged or knocked-out teeth are examples of less frequent, but more severe injuries. Treatment depends on the type, location and severity of each injury. Any dental injury, even if apparently mild, requires examination by a dentist or an endodontist immediately.
There are common misconceptions that endodontic treatments such as root canals, cause pain and/or illness and should be avoided at all costs. The exact opposite is true. The pain, inconvenience and cost of avoiding endodontic treatment in favor of tooth extraction or a wait-and-see approach can be easily avoided. The longer you postpone treatment the more you risk the chance to save your tooth.
After your procedure, your endodontist will send you home with instructions for pain management and how to care for your tooth while recovering from treatment and until a follow-up visit. Following guidelines for care is especially important if a temporary filling or crown is in place.
While uncomfortable, any pain and sensitivity following a root canal should only last a few days. Since the pain experienced after a root canal is usually mild, you’ll likely only need over-the-counter pain medications for relief. These include acetaminophen (Tylenol) and ibuprofen (Advil, Motrin IB).
Technology
Our practice utilizes state-of-the-art, small volume cone-beam CT (computed tomography – or CBCT) technology that provides highly accurate, 3-D radiographic images for the diagnosis, planning and treatment of endodontic disease. This allows three-dimensional visualization of teeth, and bone.
At York Hill Endodontics in Toronto, your health and safety is our greatest concern. In that endeavor, we have been using digital radiography since 2010. This cutting edge technology allows an approximate 80% reduction in radiation to our patients and at the same increase the diagnostic capabilities. These digital radiographs are stored in your electronic chart and can be transmitted electronically to your general dentist at any time.
This advanced technology has completely changed the scope and practice of endodontic care. The surgical microscope has expanded the field of endodontics to create micro-surgical endodontics. The magnification and illumination this technology offers, allows us to see tiny malformations in anatomy never before possible. This technology has advanced the diagnostic and treatment possibilities in all aspects of endodontic care.
A nickel titanium rotary file is an engine-driven tapered and pointed endodontic instrument made of nickel titanium alloy with cutting edges used to mechanically shape and prepare the root canals during endodontic therapy or to remove the root canal obturating material while performing retreatment.
Our integrated delivery systems keep our equipment where we need it, when we need it, We can quickly and comfortably access our endodontic tools, removing the need to get up during a procedure, or take our focus away from delivering the best in endodontic care to our patients.
Locating the appropriate apical position always has been a challenge in clinical endodontics. The electronic apex locator (EAL) is used for working length determination as an important adjunct to radiography. The EAL helps to reduce the treatment time and the radiation dose, which may be higher with conventional radiographic measurements. According to recent publications, the accuracy of frequency-dependent EALs appears to be much higher compared with traditional-type EALs (simple resistance type or impedance type).
York Hill Endodontics is completely paperless. Our client portal allows you to access all relevant information in regards to your treatment easily online. All your records are recorded electronically, thereby making the communication with your dentist of your treatment very easy. Electronic charting not only make your records more legible but also enhances the environment by reducing the use of paper.
