A key part of the procedure is making sure that the area is sufficiently numbed before treatment begins. If you have an active infection, the anesthetic injection will provide immediate relief from your discomfort. Your dentist may use multiple injection sites to ensure your tooth and surrounding tissue are completely numb. Much like a cavity, your dentist will then use a drill to expose the infected dental canals.
The damaged portion of the tooth is removed using small specialist tools. The root canals are cleaned and then filled with packing material. Some teeth may also require small posts to help increase the strength of the remaining tooth. Finally, a dental crown is placed on top of the tooth to protect the underlying structure. This procedure may be completed in two visits, with a temporary crown placed between visits to protect your tooth. After the procedure, you may have mild pain for a few days, but this should be easily managed using Advil or a similar pain killer.
