Biting with the same side teeth; root canal treatment?
Hello Doctor: I had a root canal treatment on my lower left molar around mid-November.
Since it has been a month and I am still experiencing pain, I recently returned for a check-up.
An X-ray revealed a dark shadow at the apex of the root.
The doctor suggested we observe it for another month, and if the shadow does not decrease in size, we will proceed with microscopic root canal treatment.
I would like to ask if it is possible for the dark shadow at the apex to resolve on its own?
Another question is that prior to the root canal, I was already experiencing spontaneous pain in the tooth, so for the past two months, I have been chewing on the right side (as the left side tooth after the root canal is still painful, and I have not yet had a crown placed for protection).
However, a few days ago, I noticed a slight sensitivity when biting down on something hard at the back of my right side teeth.
The doctor checked and found no cavities, suggesting that it might be due to gum inflammation from using that side of my mouth for an extended period.
How can I improve this situation? Thank you! :)

Hello: 1.
Yes, if the inflammation subsides, the shadow will gradually decrease.
Typically, follow-up observations are done every 3 to 6 months.
If there is improvement, we continue to monitor for recovery.
If there is no recovery, we may consider retreatment of the root canal.
2.
It is recommended to use desensitizing toothpaste and switch to a soft diet to reduce tooth wear.
During your next visit, please ask the dentist to confirm whether there is any damage to the pulp.

More Info
Managing tooth pain after a root canal can be a challenging experience, especially when complications arise. In your case, it seems that you are dealing with persistent pain and a radiographic finding of a dark shadow at the root apex, which may indicate an ongoing infection or inflammation. Here are some insights and recommendations based on your situation.
Understanding the Dark Shadow on X-ray
The dark shadow you see on the X-ray, often referred to as a periapical radiolucency, can be indicative of several conditions, including:
1. Persistent Infection: This could be due to incomplete cleaning of the root canals or the presence of additional canals that were not treated during the initial procedure.
2. Inflammation: Sometimes, the body may still be in a healing phase, and the shadow could represent inflammation rather than an active infection.
3. Necrotic Tissue: If there is still necrotic (dead) tissue present in the root canal system, it can lead to ongoing symptoms.
While it is possible for the dark shadow to resolve on its own, especially if the inflammation is the primary issue, it is more common for it to require further intervention, particularly if there is an underlying infection. Your dentist's recommendation to observe for another month is reasonable, but if the shadow does not decrease in size, a microscopic root canal treatment may be necessary to ensure all infected tissue is removed.
Managing Pain and Discomfort
In the meantime, here are some tips for managing your pain and discomfort:
1. Pain Management: Continue using over-the-counter pain relievers as directed. Nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen can help reduce inflammation and pain. If the pain is severe, your dentist may prescribe stronger medications.
2. Oral Hygiene: Maintain excellent oral hygiene to prevent further complications. Gently brush and floss around the affected area, being careful not to irritate it further. Rinsing with warm salt water can help soothe the gums and reduce inflammation.
3. Dietary Adjustments: Since you have been favoring your right side for chewing, it’s important to be cautious with that side as well. Eating soft foods and avoiding hard or crunchy items can help minimize discomfort. If you experience sensitivity when biting down, it may be a sign of gum inflammation or other issues.
4. Follow-Up Care: Keep your follow-up appointments with your dentist. If you notice any changes in your symptoms, such as increased pain, swelling, or fever, contact your dentist immediately.
Addressing Gum Inflammation
Regarding the mild discomfort you are experiencing on the right side, it is indeed possible that prolonged use of that side for chewing has led to gum irritation or inflammation. Here are some strategies to alleviate this:
1. Warm Compress: Applying a warm compress to the outside of your cheek can help soothe inflammation and promote blood flow to the area.
2. Avoid Irritants: Stay away from spicy or acidic foods that may further irritate your gums.
3. Gentle Massage: Gently massaging the gums with a clean finger can help improve circulation and reduce discomfort.
4. Consultation: If the discomfort persists, consider discussing it with your dentist. They may recommend a professional cleaning or other treatments to address any underlying issues.
Conclusion
In summary, while it is possible for the dark shadow on your X-ray to resolve on its own, it is crucial to monitor your symptoms closely and maintain communication with your dentist. Managing pain effectively and ensuring proper oral hygiene will aid in your recovery. If symptoms persist or worsen, further intervention may be necessary to address any underlying issues. Always feel free to reach out to your dental care provider with any concerns or questions you may have during your recovery process.
