Root Canal Retreatment: Preserving Your Natural Teeth at Schaefer Dental Group in Lansing, Michigan
Most of the time, initial root canal therapy is effective at permanently relieving tooth pain and halting infection deep inside the tooth. However, occasionally, the body may not heal as expected. After some time, you may experience pain in the affected tooth again—or X-rays may reveal that infection is still present near the roots. In this situation, you may need root canal retreatment.
Why Initial Root Canal Treatment May Fail
There are several reasons why your initial root canal procedure may not have succeeded. The root canals are slender, intricate passageways deep inside the tooth that house the nerves and blood vessels (the tooth’s soft “pulp”). Issues leading to the need for retreatment include:
-
Intricate Anatomy: The canals can be so narrow and forking that some may have gone undetected or failed to respond completely to the first treatment.
-
Recontamination: The canals might have become reinfected via several routes, such as a delayed or ineffective crown restoration, new tooth decay, advancing gum disease, or a cracked or fractured tooth.
Evaluating Your Options with Your Lansing Dentist
If initial root canal (endodontic) therapy has failed, the first step is to evaluate your options with the team at Schaefer Dental Group. Besides retreatment, the alternatives may include endodontic surgery or extraction (removal) of the tooth. Because a missing tooth should be replaced with a dental implant, a bridge, or a partial denture—none of which are simple or inexpensive options—we prefer to help you retain your natural teeth whenever possible. Retreatment is often the best path to preserving the tooth.
The Root Canal Retreatment Procedure
If endodontic retreatment is appropriate, the procedure performed by your dentist in Lansing, Michigan is similar to a routine root canal, with a few added measures:
-
Anesthesia: The area is numbed, usually with a local anesthetic.
-
Access and Removal: Any existing restorations (like crowns) will be altered to provide access to the root canal filling material. A small opening is made to remove the old filling material and any obstructions.
-
Cleaning and Disinfection: The pulp chambers are thoroughly cleaned and disinfected using tiny instruments. A microscope and light are typically used to search carefully for additional canals or unusual structures that might have been missed previously. Complex cases may require a subsequent visit.
-
Sealing and Restoration: When all canals have been cleaned and disinfected, they are filled with inert material and sealed. A temporary filling is then placed in the tooth. A permanent restoration will be placed at a later time.
Is Retreatment Your Best Choice?
While no medical or dental procedure can guarantee 100% success, endodontic retreatment offers a good chance of success in many instances, even though it can be more complex than the initial therapy. Since the field of endodontics is constantly evolving, new techniques may be available now that weren’t used during your first procedure.
The dental professionals at Schaefer Dental Group are committed to helping you understand the risks, benefits, and alternatives for treating root canal problems. When we recommend retreatment, it’s because we believe it is the best way for you to preserve your natural teeth and enjoy them for many years to come.
