Endodontic Re-Treatment
Written by

In some cases, however, a tooth that has received endodontic treatment fails to heal or the pain continues. Occasionally, the tooth becomes painful or diseased months or even years after successful treatment. If your tooth has failed to heal or has developed new problems, you have a second chance. Another endodontic procedure may be able to save your tooth.

As occasionally happens with any dental or medical procedure, a tooth may not heal as expected after initial treatment for a variety of reasons:

  • Narrow or curved canals were not treated during the initial procedure.
  • Complicated canal anatomy went undetected in the first procedure.
  • The crown or other restoration was not placed soon enough after the procedure.
  • The restoration did not prevent saliva from contaminating the inside of the tooth.    

 In other cases, a new problem can jeopardize a tooth that was successfully treated. For example:

  • New decay can expose the root canal filling material to bacteria, causing a new infection in the tooth.
  • A loose, cracked or broken crown or filling can expose the tooth to new infection.  


1st Appointment 

  • Crown, post, and core material - must be disassembled and removed to permit access to the root canals.
  • After removing the canal filling, the endodontist can clean the canals and carefully examine the inside of your tooth, searching for any additional canals or unusual anatomy that requires treatment.
  • After cleaning the canal(s), the endodontist will dress the canal(s) and place a temporary filling and wait for the healing of an infection which generally takes 1 week to a month depending on the size of infection.(same as the first root canal treatment) 

2nd Appointment

  • Once the infection will has cured, the endodontist will fill and seal the canal(s) and place a temporary filling in the tooth.* Post & Core insertion and preparation a tooth for a crown maybe carried out this time.              

3rd Appointment

  • Fitting of a permanent crown

Retreated teeth can function well for years, even for a lifetime. It's always best to save the tooth if your endodontist believes retreatment is the best

Advances in technology are constantly changing the way root canal treatment is performed, so your endodontist may even be able to use a new technique that was not available when you had your first procedure. If your tooth has unusual anatomy that was not cleaned and sealed during the first procedure, your endodontist may be able to resolve this problem with a second treatment.

Endodontic Surgery

  • Surgery can help save your tooth in a variety of situations.
  • Surgery may be used in diagnosis. If you have persistent symptoms but no problems appear on your x-ray, your tooth may have a tiny fracture or canal that could not be detected during nonsurgical treatment. In such a case, surgery allows your endodontist to examine the entire root of your tooth, find the problem, and provide treatment.
  • Sometimes calcium deposits make a canal too narrow for the instruments used in nonsurgical root canal treatment to reach the end of the root. If your tooth has this "calcification," your endodontist may perform endodontic surgery to clean and seal the remainder of the canal.
  • Usually, a tooth that has undergone a root canal can last the rest of your life and never need further endodontic treatment. However, in a few cases, a tooth may not heal or become infected. A tooth may become painful or diseased months or even years after successful treatment. If this is true for you, surgery may help save your tooth.
  • Surgery may also be performed to treat damaged root surfaces or surrounding bone.


Although there are many surgical procedures that can be performed to save a tooth, the most common is called apicoectomy or root-end resection. When inflammation or infection persists in the bony area around the end of your tooth after a root canal procedure, your endodontist may have to perform an apicoectomy.

A small filling may be placed in the root to seal the end of the root canal, and a few stitches or sutures are placed in the gingiva to help the tissue heal properly.

ver a period of months, the bone heals around the end of the root.

Your dentist or endodontist is suggesting endodontic surgery because he or she believes it is the best option for saving your own natural tooth. Of course, there are no guarantees with any surgical procedure. Your endodontist will discuss your chances for success so that you can make an informed decision.

ften, the only alternative to surgery is extraction of the tooth. The extracted tooth must then be replaced with an implant, bridge, or removable partial denture to restore chewing function and to prevent adjacent teeth from shifting. Because these alternatives require surgery or dental procedures on adjacent healthy teeth, endodontic surgery is usually the most biologic and cost-effective option for maintaining your oral health.

No matter how effective modern artificial tooth replacements are—and they can be very effective—nothing is as good as a natural tooth. You've already made an investment in saving your tooth. The pay-off for choosing endodontic surgery could be a healthy, functioning natural tooth for the rest of your life.

Root Canal Treatment or Endotontic treatment refers to the specialized dental procedure of removing damaged or infected dental pulp from a tooth and filling it with biocompatible and inert materials. It is a method that prevents the further developing and spreading of infection and the possibility of that tooth falling out. Root canal therapy is recommended in instances where an abscess (a pocket of pus that forms at the tip of the tooth's root) becomes visible.


1st Appointment 

1.1 Open an access and removal of damaged dental pulp tissues,nerves and blood vessels.



1.2 Apply dressing with root canal medicines and protect with a temporary filling From this point the tooth is cleaned out and any bacteria toxins nerve tissue and related debris within the tooth are removed. The cleaning process extends the entire length of the tooth's root canal(s) but not beyond.
Following the cleaning portion of the root canal procedure is the filling in and sealing up of the tooth's root's interior with root canal filling material usually gutta percha (a natural rubber). The hole that was drilled in order for access to the tooth's root is then sealed with the placing of a filling.
The tooth must be restored permanently by permanent fillings or else post & core and a crown , depending on remaining tooth structure.





2nd Appointment

2.1 Remove a temporary filling and root canal medicines and fill with root canal filling.


2.2 Insert a Post & Core, Prepare a tooth for a crown, Mold ,Fabrication and insertion of a Temporary crown It takes 2-3 days in the laboratory to fabri- cate a permanent crown.


3rd Appointment

Fitting of a permanent crown For some patients, root canal therapy is one of the most feared dental procedures, perhaps because of a painful abscess that necessitated the root canal procedure. However, dental professionals assert that modern root canal treatment is relatively painless because the pain can be controlled with a local anesthetic during the procedure and pain control medication can be used before and/or after treatment assuming that the dentist takes the time to administer one.
