Root Canal Retreatment

Root Canal Treatment and Retreatment for Rockford, IL Patients

If your tooth is badly damaged or infected, your dentist may recommend a root canal procedure. Root Canal Treatment is very similar to having a routine filling and can usually be completed in one or two appointments. Reasons for endodontic treatment range from a faulty crown to decay caused by repeated procedures done to the tooth. By saving the natural tooth, patients can continue to chew efficiently and maintain a natural smile. If you have a cracked or damaged tooth, please fill out our online form to request an appointment.

Root Canal Treatment

During this procedure, the dentist or oral surgeon will remove the damaged pulp, carefully disinfecting it before filling it and sealing it with a type of cement. It will typically be performed under local anesthesia and will not cause a significant amount of pain.

Root canal treatments are a better alternative than extraction for most individuals. If a tooth has good bone support, a solid surface and healthy gums beneath it, it stands a good chance of being saved. Opting for root canal treatment can be far less expensive than the alternatives. For example, dental implants, extensive bridgework, and the creation of aesthetically pleasing prosthetic teeth cost far more than working with the natural tooth. They also require maintenance and feel less natural than a “real” tooth.

Why is Root Canal Retreatment Required?

In rare cases, root canal therapy fails to work as expected. The treated tooth might not heal properly, or a patient might experience post-surgical complications that jeopardize the tooth. Root canal retreatment involves the removal of the previous crown and packing material, the cleaning of the root canals, and the re-packing and re-crowning of the tooth.

Though the prospect of more endodontic surgery might not be pleasant, root canal retreatment is relatively simple. In short, root canal retreatment is almost identical to the original procedure, aside from the structural removal. The success rate for a root canal retreatment runs at around 60%. The whole treatment can be completed in 1-3 visits.

There are some reasons why root canal therapy unexpectedly fails, including a cracked crown leaking filling material, curved or narrow canals not treated during the original procedure, new decay to the tooth, a new fracture in the treated tooth, saliva entering the restorative structure, and other undetected complex canal structures.

What Does Root Canal Retreatment Involve?

On the day of the retreatment procedure, a local anesthetic will be administered, unless another type of anesthetic has been selected. The amount the dentist can do within a single appointment will much depend on the amount of inflammation present, and the complexity of the treatment.

The first step in a root canal retreatment is to gain access to the inner tooth. If a crown and post have been placed, these will be removed.

Next, filling material and obstructions that block the root canals will be removed. This removal is conducted using an ultrasonic handpiece. The advantage of using this tool is that any unwanted material is vibrated loose. Tiny instruments will then be used to clean and reshape the root canals. X-rays may be taken to ensure that the roots are thoroughly clean. If this part of the treatment proves to be complex, medicated packing material will be applied, and the rest of the cleansing procedure will be done at the next visit.

When the dentist is confident that the root canals are clean, gutta-percha is used to pack the space. This rubbery material seals the canals to prevent bacterial invasion. Finally, the dentist applies a temporary crown or filling to the tooth. At a later date, the color-matched permanent crown will be placed.
