Sometimes, even after retreatment of the root, the infection may remain in the small canals, which are part of the tooth’s main canals, which prevent restoration. In these cases, the end of the root or the apex is removed along with the infected tissue around it; the filling procedure is performed. Endodontic therapy is performed to prevent tooth extraction. Endodontics is also called the operation of cutting the tip of the roots. In this method, the surgeon cuts the tissue around the gum to gain access to the bone in it and, in this way, removes the infected tissue. According to one of the best endodontist in Oakville, a common misunderstanding is that if conventional root canal treatment fails, the tooth must undergo microsurgery to correct it. While most endodontic failures are best cured by re-endodontic treatment, microsurgery is unnecessary. After deciding on the necessity of apical surgery, the surgery is performed by a surgeon or an endodontist.
Steps of Endodontic Surgery
First step: anesthetize the surgical site
1- Before doing anything, you will be given local anesthesia to numb the area around the damaged tooth.
Second step: cut the gum
2- Your dentist or veneer specialist cuts the gum and pulls the gum tissue aside to reach the root.
The third step: removing the infected tissue at the end of the root
3- The infected tissue at the end of the root is removed. Usually, only a few millimeters of the root are removed, as is any infected tissue around the root.
Fourth step: cleaning the root from infection and filling it with material
4- Finally, the inside of the root canal is once again washed from the end of the root and cleaned of any infection, and filled with new materials.
Fifth step: Radiography
5- Finally, an X-ray is taken to ensure that the tooth’s condition is complete and appropriate, and after the final confirmation, the gums are sutured in place.
In What Cases Is Epio Dental Surgery Recommended?
Anatomical problems: calcification, obstruction, or curvature of the root that prevents the filling of the root canal. In such a situation, even though the result may be in question, root canal treatment is still preferable to surgery.
Dental Restorative Considerations: Preparing an access hole from a dental veneer may be difficult and compromise the veneer’s hold or cause root perforation.
Crowned teeth with post & core: These teeth face the risk of root fracture during post-removal. In these cases, apical dental surgery is recommended.
Mistakes during work: creating a log, breaking the device, or perforating the root can lead to treatment failure. Surgical correction is necessary in these cases.
Large unhealed lesions after endodontic treatment
In What Cases Is Epico Not Recommended?
Root canal treatment is possible.
Anatomical considerations: the presence of vessels and nerves or bony structures such as the external oblique ridge or the possibility of the maxillary sinus opening
Low crown-to-root length ratio
Systemic problems of the patient.
What Are the Alternatives to Periapical Surgery?
Often, the only alternative to surgery is tooth extraction. Then, the extracted tooth should be replaced with an implant, bridge, or removable prosthesis to restore chewing function and prevent displacement of adjacent teeth. Because these options require surgery or dental procedures on adjacent healthy teeth, root canal surgery is usually the most biological and cost-effective option for maintaining oral health.
