Post-Root Canal Treatment Issues


Hello, about five years ago, I had a root canal treatment on one of my lower molars (the first two molars).
It had a slight fracture once, so I later used silver powder to fill it.
At that time, the doctor mentioned that my jaw was still developing and suggested waiting until I was 20 to consider further treatment.
It has been over four years, and currently, there are no issues with the tooth.
If I continue to be careful not to bite hard objects, is it feasible to maintain the current condition? If I accidentally bite something hard and it fractures, what would the treatment options be? My wisdom teeth are horizontally impacted, with only a small portion exposed and the rest covered by gum tissue.
Is it possible to extract the tooth that underwent root canal treatment and then align the wisdom teeth to fill the gap?

Hello: The molars are the focal point of occlusion and should be protected with crowns; otherwise, over time, the tooth structure can easily fracture.
If the fracture extends too deep below the gum line, it may become irreparable.
The conditions for wisdom teeth are not ideal, and correcting them with orthodontics may end up costing even more.
Wishing you peace, health, and well-being.
Sincerely, Dr.
Huang Chih-Cheng, Director of Dentistry, Taoyuan General Hospital, Ministry of Health and Welfare.

Post-root canal treatment concerns are quite common, and it's understandable to have questions about the long-term care and potential complications following such a procedure. Let's break down your concerns and provide some clarity on each aspect.

Firstly, it’s great to hear that your treated tooth has not shown any significant issues over the past four years. After a root canal treatment, it is essential to maintain good oral hygiene and regular dental check-ups to monitor the health of the treated tooth and surrounding structures. As you mentioned, avoiding hard foods can help prevent any potential damage to the tooth. However, it’s important to recognize that even with careful management, there is always a risk of fracture, especially if the tooth has previously been compromised.

If you do happen to bite down on something hard and the tooth fractures, the treatment options will depend on the extent of the fracture. Minor fractures may be repaired with dental bonding or a filling, while more significant fractures might require a crown to restore the tooth's function and aesthetics. In severe cases, if the fracture extends below the gum line or compromises the tooth's integrity, extraction may be necessary. It’s advisable to consult your dentist immediately if you experience any pain or notice a fracture, as early intervention can often save the tooth.

Regarding your wisdom teeth, particularly the horizontally impacted one, it is crucial to evaluate its position and the potential for complications. Wisdom teeth can sometimes cause crowding or misalignment of adjacent teeth, especially if they are impacted. If you decide to have the root canal-treated tooth extracted, it may create space that could allow for orthodontic treatment to correct the alignment of your other teeth, including the wisdom tooth. However, this would depend on the specific circumstances of your dental structure and the advice of your orthodontist or oral surgeon.

In terms of orthodontic treatment, if the wisdom tooth is extracted, your orthodontist may recommend braces or other appliances to help shift the remaining teeth into a more desirable position. This process can help fill in gaps and improve overall dental alignment. It’s essential to have a comprehensive evaluation by your dental care team to determine the best course of action based on your unique dental situation.

Lastly, it’s worth noting that while root canal treatments are generally successful, some patients may experience post-treatment discomfort or complications, such as persistent pain or infection. If you notice any changes in your treated tooth, such as increased sensitivity, swelling, or pain, it’s crucial to contact your dentist promptly. They may recommend further imaging, such as an X-ray, to assess the condition of the tooth and surrounding bone.

In summary, maintaining good oral hygiene, avoiding hard foods, and having regular dental check-ups are key to ensuring the longevity of your root canal-treated tooth. If any issues arise, prompt consultation with your dentist will help address them effectively. As for your wisdom teeth, a thorough evaluation will guide you on the best path forward, whether it involves extraction or orthodontic treatment. Always communicate openly with your dental care team about your concerns and treatment options to ensure the best outcomes for your oral health.
