Root Canal Retreatment
Why do I need another endodontic procedure?
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 placement of the crown or other restoration was delayed following the endodontic treatment.
The restoration did not prevent salivary contamination to 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.
A tooth sustains a fracture.
What will happen during retreatment?
First, we will discuss your treatment options. If retreatment is chosen, we will reopen your tooth to gain access to the root canal filling material. In many cases, complex restorative materials—crown, post and core material—must be disassembled and removed to permit access to the root canals.
After removing the canal filling, we can clean the canals and carefully examine the inside of your tooth using magnification and illumination, searching for any additional canals or unusual anatomy that requires treatment.
After cleaning the canals, we will disinfect and often medicate them for a few weeks. Then we will fill and seal the canals and place a temporary filling in the tooth. If the canals are unusually narrow or blocked, we may recommend endodontic surgery. This surgery involves making an incision to allow the other end of the root to be sealed.
After we complete retreatment, you will need to return to your dentist within the next few weeks to have a new crown or other restoration placed on the tooth to protect and restore it to its full function.
Is retreatment the best choice for me?
Whenever possible, it is best to save your natural tooth. Retreated teeth can function well for years, even for a lifetime.
Advances in technology are constantly changing the way root canal treatment is performed, so we will probably use new techniques that were not available when you had your first procedure.
As with any dental or medical procedure, there are no guarantees. We will definitely discuss your options and the chances of success before beginning retreatment.
How much will the procedure cost?
The cost will be discussed before any treatment is rendered. The procedure will be more complex than your first root canal treatment, because your restoration and filling material may need to be removed to accomplish the new procedure. In addition, we may need to spend extra time searching for unusual canal anatomy.
While dental insurance may cover part or all of the cost for retreatment, some policies limit coverage to a single procedure on a tooth in a given period of time. Our staff will check your insurance coverage, explain it to you and inform you of what your expected portion will be.
What are the alternatives to retreatment?
If nonsurgical retreatment is not an option, then endodontic surgery should be considered. This surgery involves making an incision to allow access to the tip of the root. Endodontic surgery may also be recommended in conjunction with retreatment. We will discuss your options and recommend appropriate treatment.
What are the alternatives to endodontic retreatment and/or endodontic surgery?
The only other alternative is extraction of the tooth. The extracted tooth will need to be replaced with an implant, bridge or removable partial denture to restore chewing function and to prevent adjacent teeth from shifting. Because these options require extensive surgery or dental procedures on adjacent healthy teeth, they can be far more costly and time consuming than retreatment and restoration of the natural tooth.
No matter how effective tooth replacements are—nothing is as good as your own natural tooth. You’ve already made an investment in saving your tooth. The payoff for choosing retreatment could be a healthy, functioning natural tooth for many years to come.
