Improper healing may be caused by the following:
In some cases, new problems can influence a tooth that was successfully treated:
What will happen during re-treatment?
First, the endodontist will discuss your treatment options. If you and your endodontist choose re-treatment, the endodontist will reopen your tooth to gain access to the root canal filling material. In many cases, complex restorative materials - crowns, posts, and core material - must be disassembled and removed to permit access to the root canal.
After removing the canal filling, the endodontist can clean the canals and carefully examine the inside of your tooth, carefully searching for any additional canals or unusual anatomy that requires treatment.
After cleaning the canal(s), the endodontist will fill and seal the canal(s) and place a temporary filling in the tooth*. Post space may also be prepared at this time.
After the final visit with your endodontist, you will need to return to your dentist as soon as possible to have a new crown or other restoration placed on the tooth to protect and restore it to full function.
* If the canals are unusually narrow or blocked, your endodontist may recommend endodontic surgery. This surgery involves making an incision near the end of the root to allow the tip of the root to be sealed.
Is re-treatment the best choice for me?
Retreated teeth can function well for years, even for a lifetime. It’s always best to save the tooth if your endodontist believes re-treatment is the best option for you.
Technological advances 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.
Of course, there are no guarantees with any dental or medical procedure. Your endodontist will discuss your options and the chances of success before beginning re-treatment.
What are the alternatives to re-treatment?
For some patients considering re-treatment, endodontic surgery is also an option. This surgery involves making an incision near the end of the root to allow the tip of the root to be sealed. Endodontic surgery may be recommended in conjunction with re-treatment or as an alternative. Your endodontist will discuss your options and recommend the appropriate treatment.
The only other alternative is the extraction of the tooth. The extracted tooth must then be replaced with an implant, bridge, or removable partial denture to restore the chewing function and 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 re-treatment and restoration of the natural tooth.
No matter how effective modern tooth replacements are - and they can be very effective - nothing is as good as your natural tooth. You’ve already made an investment in saving your tooth. The payoff for choosing re-treatment could be a healthy, functioning natural tooth for many years to come.
