Root Canal Retreatment

There are some rare cases where root canal therapy fails to deliver the expected result. The tooth might not heal properly after treatment or some post-surgical complications might occur which endangers the tooth. Root canal therapy involves removing the previous filling material crown, cleansing the root canals, and re-crowning the tooth. In fact, root canal therapy is very similar to the original procedure, albeit the structural removal. Root canal retreatment has a success rate of about 75%.

For most individuals, Root canal treatments as well retreatments area much better alternative than extraction. A tooth with a decent bone support, healthy surface and gums stand a good chance of being saved. Root canal treatment can be cheaper than the other alternatives. The creation of aesthetically attractive prosthetic teeth, extensive bridgework, and dental implants are all cheaper than working with the natural tooth. They also need to be maintained and are not as natural as a “real” tooth.

Why is root canal retreatment required?

Though the thought of having to undergo more endodontic surgery might not be pleasing, root canal therapy is a simple procedure. Generally, entire treatment can be completed in at most three visits.

Some of the reasons why root canal therapy fails unexpectedly includes:

  • Narrow or curved canal not treated during the initial procedure
  • Cracked crown leaking filling material
  • New decay of the tooth.
  • Delay in placing restorative appliances after the procedure
  • Saliva entering the restorative structure
  • New fracture in the treated tooth
  • Unnoticed complex canal structures

What does root canal retreatment involve?

During the treatment procedure, a local anesthetic is administered, unless the dental professional has chosen another type of anesthetic. A rubber dam is used to isolate the affected area. The dam helps in protecting the tooth from saliva and bacteria during treatment. The amount of effort the dentist needs to put in within a single appointment will depend on the degree of inflammation present, as well the complexity of the treatment.

During a root cal treatment, the first step is to be able to access the inner tooth. any crown that has been placed will be removed.

Then filling material and other things that block the root canals are removed. An ultrasonic handpiece is used to carry out this removal. The instrument is then used to reshape and clean the root canals. X-rays may also be taken to determine whether the roots are completely clean. If this part of the process becomes complex, a medicated packing material will is applied, and the remaining part of the cleansing process will be done at the next appointment.

When the root canal has been confirmed clean by the dentist, the space is packed with gutta-percha – a rubbery material that helps seal the canal to prevent the invasion of bacteria. Finally, a temporary filling or crown is applied to the tooth. the color-matched permanent crown is then placed at a later date.
