Old filling material protruding from the root canal opening?
Dear Dr.
Lin,
Last July, I developed a pus-filled abscess on my upper left canine.
An X-ray revealed that the tooth root was resorbed and had an opening.
I began treatment in late October, and after several attempts, the large post was removed, and I underwent a microsurgical root canal treatment.
The abscess disappeared afterward, but there is a foreign object protruding from the root canal opening, which resembles a thin metal piece with bristles on both sides, similar to a brush or feather.
What could that object be? Should it be surgically removed? Will leaving it outside the root canal pose any risks, such as causing inflammation in the tooth or oral cavity due to material degradation over time? The abscess disappeared in January of this year, the root canal opening was sealed in February, and I was initially planning to get a crown in April, but suddenly this concern arose.
I kindly ask for your clarification on this matter.
Thank you very much!

Hello: In your case, the abscess has disappeared, indicating that the treatment has been successful in the short term.
As for the material that has protruded from the root canal, it could be the filling material, medication placed inside, or a broken instrument.
You should discuss and seek clarification from the endodontist who performed the root canal treatment.
If you would like a second opinion, it is advisable to visit a medical center for another X-ray to provide further evidence and discuss it with a physician.
Sincerely, Lin Chia-Yung, Department of Dentistry, Taichung Hospital, Ministry of Health and Welfare.

More Info
The situation you are describing involves a complex dental issue that requires careful consideration and evaluation. Based on your description, it seems that after undergoing a root canal treatment, you have noticed an object protruding from the root canal opening of your upper left canine tooth. This object appears to be a thin metal structure with bristle-like extensions, resembling a brush or feather.
Possible Explanations for the Object
1. Old Filling Material: The object could be remnants of the filling material that was used during your previous root canal treatments. Sometimes, materials such as gutta-percha or other sealing compounds can extrude beyond the root canal space, especially if there was an issue during the sealing process.
2. Fragment of Dental Instrument: It is also possible that this object is a fragment of a dental instrument that may have broken off during the procedure. Instruments used in root canal therapy are designed to be durable, but breakage can occur, particularly in complex cases.
3. Foreign Body Reaction: If the object is indeed a foreign material, it could potentially lead to a foreign body reaction, which might cause inflammation or infection if not addressed.
Should It Be Surgically Removed?
Whether or not this object should be surgically removed depends on several factors:
- Symptoms: If you are experiencing pain, swelling, or any signs of infection, it is crucial to consult your dentist or an endodontist (a specialist in root canal therapy) as soon as possible. Persistent symptoms may indicate that the object is causing irritation or infection.
- Radiographic Evaluation: A follow-up X-ray can help determine the nature of the object and its relationship to the surrounding bone and tissues. This imaging will provide valuable information to your dentist regarding whether the object poses a risk.
- Professional Assessment: It is advisable to seek a second opinion from a dental specialist if you have concerns about the object. They can assess whether it is necessary to remove it surgically or if it can be monitored over time.
Potential Risks of Leaving the Object
Leaving the object in place could potentially lead to complications, including:
- Infection: If the material is not biocompatible or if it causes irritation, it could lead to a localized infection, which might manifest as pain, swelling, or the formation of another abscess.
- Chronic Inflammation: Over time, the presence of foreign material can lead to chronic inflammation, which may affect the surrounding tissues and bone.
- Compromised Healing: If the root canal was intended to heal and the object interferes with this process, it could compromise the overall success of the treatment.
Conclusion
In summary, the object you are observing could be a remnant of filling material or a fragment of a dental instrument. It is essential to consult with your dentist or an endodontist for a thorough evaluation, including radiographic imaging, to determine the best course of action. If the object is causing symptoms or poses a risk of infection, surgical removal may be warranted. Regular follow-ups and maintaining good oral hygiene will also be crucial in ensuring the health of your tooth and surrounding tissues. Always prioritize open communication with your dental care provider regarding any concerns you may have during your treatment process.
