Issues related to root canal treatment?

Hello, Doctor.
I had four anterior teeth restored with crowns ten years ago.
This year, I was involved in a car accident that resulted in a fracture of my maxilla.
I have undergone fixation, and it has been 6.5 months since the injury.
The bone has healed, but the accident caused damage to my prosthetic teeth, and I sometimes experience swelling in my gums.
I would like to have this addressed, but the doctor mentioned that my previous root canal treatments on those four teeth were unsuccessful and have become calcified, making further root canal treatment difficult.
If the root canals fail, it could lead to recurrent inflammation, and I would not be able to have a prosthesis.
There is also a risk of root fracture, extraction, and I cannot use the adjacent canine teeth for support.
Could these issues really occur? What should I do? Thank you!

Hello: Whether the root of your front tooth is fractured after the car accident is crucial.
If there is no root fracture, even if the root canal has calcified as the doctor mentioned, you can still seek treatment from an endodontist.
Even if traditional root canal treatment fails, surgical methods (apicoectomy and retrograde filling) can still save the tooth.
Sincerely, Dr.

The situation you are facing is indeed complex and requires careful consideration of various factors related to your dental health. After undergoing root canal treatment (RCT) on your anterior teeth a decade ago, and following a traumatic incident such as a car accident, it is crucial to understand the potential complications that may arise, particularly in relation to the integrity of the treated teeth and the surrounding structures.

Firstly, the term "calcification" refers to the hardening of the pulp tissue within the root canal system, which can occur after a root canal treatment. This can make subsequent treatments more challenging, as the canals may become narrower and more difficult to access. If the previous root canal treatments were not successful, there is a possibility of persistent infection or inflammation, which can lead to further complications such as abscess formation or even tooth loss.

In your case, the fact that you are experiencing swelling in the gum tissue could indicate that there is still an underlying infection or inflammation associated with the previously treated teeth. This is a significant concern, as untreated infections can lead to more severe complications, including the potential for the roots of the teeth to fracture. If the roots are compromised, it may indeed necessitate extraction of the affected teeth.

Regarding the ability to place a prosthetic (dentures or bridges) after extraction, it is essential to consider the structural support provided by adjacent teeth. If the neighboring canine teeth are not suitable for supporting a bridge due to their health or alignment, this could limit your options for restoration.
Your dentist's recommendation to possibly extract the teeth if the root canals are deemed irreparable is a common approach in dentistry. However, before proceeding with extraction, it may be beneficial to seek a second opinion, particularly from an endodontist (a specialist in root canal treatment). They may offer advanced techniques such as retreatment of the root canals or surgical options like apicoectomy, which involves removing the tip of the root and sealing it to eliminate infection.

In summary, the challenges you face after dental trauma and previous root canal treatments are significant. It is crucial to address any signs of infection promptly and to explore all possible treatment options. Consulting with a specialist can provide you with a clearer understanding of your situation and the best course of action. Remember, preserving your natural teeth is often preferable, and advancements in dental technology may offer solutions that were not previously available. Always ensure that you are comfortable with your treatment plan and that all your questions are addressed by your dental care provider.
