Fig. 2: This figure illustrates the procedure for endodontic microsurgery. After significant anesthesia, the gums are lifted up and the infection is removed along with the last 3-5mm of the root tip. The tooth is examined under a high power microscope for any extra canals and/or damage, including fractures. The edge of the root is cleaned with special ultrasonic instruments.
What is endodontic microsurgery? Endodontic microsurgery can be used to find fractures, damaged areas of the root, or hidden nerve canals. Endodontic microsurgery can be used as an alternative, or in addition to retreatment to address infections that remain after initial root canal therapy. In most cases, endodontic microsurgery is focused on the root tip. This is where the anatomy is most complex and hidden nerve canals are often found. The procedure starts with a small incision in the gums. This creates a window to access the problem root and surrounding infection. The very tip of the root (usually 3-5mm) is removed along with the damaged tissue. A root-end filling is placed to prevent reinfection of the root and the gum tissue is put back in place with stitches. The bone naturally heals around the root and the tooth will be fully functional. Minor swelling and discomfort may be experienced for the first couple days afterwards. This is normal for any surgical procedure.
