Dental Issues: Pain, Root Canal Treatment, and Sinus Concerns - Dentistry

Pressing on the cheek near the nostrils feels like there are holes in the gums?


A year ago, when I had a tooth extraction on the lower left side, I also experienced swelling and pain in the right cheek near the nostril.
When I press on the cheek close to the nostril, I feel a slight pain from what seems like a small hole that has persisted for several months.
An X-ray showed a shadow, and I have undergone root canal treatment for the cavity above the gum three times, but the discomfort from the hole remains.
The doctor is considering sealing it.

Should I continue with root canal treatment in my situation? Could multiple root canal treatments harm the gums? If I do not continue with root canal treatment, is there a risk of viral infection or gum deterioration due to the hole near the sinus? I have been receiving periodontal treatment at a teaching hospital for the past two years and had previously mentioned to the doctor that my gums felt slightly painful, but the doctor said there was no cavity.
Now, that tooth has decayed, which is quite frustrating.
Did I consult the wrong specialty? Which specialty should I see now? Thank you for taking the time to respond!

Dear user,
In response to your inquiry, here is the information: Your tooth is currently undergoing root canal treatment, and the duration of the treatment depends on individual clinical conditions.
If you are experiencing any discomfort, it is advisable to communicate this with your dentist.
If your symptoms have improved, you may consider completing the treatment.
After the treatment is finished, follow your dentist's instructions for regular follow-up appointments.
Generally, root canal treatment should not harm the gums.
If you have any uncertainties regarding your treatment, it is recommended that you consult and communicate with your dentist.
Regarding periodontal disease, in addition to maintaining good oral hygiene, it is important to collaborate with a periodontist for regular follow-ups and treatment to achieve better outcomes.
Thank you for your question.

Your situation sounds quite complex and understandably distressing. It appears that you have been dealing with persistent dental issues, including pain and discomfort in the area surrounding your left lower tooth, which has undergone multiple root canal treatments. Additionally, the involvement of your sinus area raises further concerns that need to be addressed.

Firstly, it’s essential to understand that root canal treatment (RCT) is designed to remove infected or damaged pulp from inside the tooth, thereby alleviating pain and preserving the tooth. However, if the infection persists or if there are additional canals that were not adequately treated, it can lead to ongoing discomfort. The fact that you have undergone RCT three times suggests that there may be a more complex issue at play, such as an undetected fracture in the tooth or a persistent infection that has not been fully resolved.

Regarding your concerns about whether to continue with root canal treatment, it is crucial to consult with a specialist, such as an endodontist. An endodontist is a dentist who specializes in diagnosing and treating issues related to the dental pulp and surrounding tissues. They can perform advanced imaging, such as a cone beam computed tomography (CBCT) scan, to get a clearer picture of the tooth's condition and the surrounding structures, including the sinus cavity.

As for the potential harm to the gums from repeated root canal treatments, while the procedure itself is generally safe, excessive treatment can lead to weakening of the tooth structure and surrounding tissues. If the tooth is deemed non-restorable, extraction may be necessary to prevent further complications.

Your concern about the proximity of the dental issue to the sinus cavity is valid. Infections in the upper teeth can sometimes extend to the sinuses, leading to sinusitis or other complications. If there is a persistent hole or defect in the bone or gum tissue, it could potentially allow bacteria to enter, leading to further infection. Therefore, it is essential to address this issue promptly.

Given your history of dental problems and the current symptoms, it may be beneficial to seek a consultation with an oral surgeon or a periodontist. An oral surgeon can evaluate the structural integrity of the tooth and surrounding bone, while a periodontist specializes in gum health and can assess any gum-related issues that may be contributing to your discomfort.

In summary, I recommend the following steps:
1. Consult an Endodontist: Get a thorough evaluation of the tooth and surrounding area, including advanced imaging to check for any hidden issues.


2. Consider an Oral Surgeon or Periodontist: If there are concerns about the integrity of the tooth or the health of the gums, these specialists can provide targeted treatment options.

3. Monitor Symptoms: Keep track of any changes in your symptoms, including pain levels, swelling, or any new sensations, and report these to your dental care provider.

4. Discuss Treatment Options: Depending on the findings, you may need to consider further root canal treatment, extraction, or other interventions to address the underlying issues.

It's important to advocate for your health and ensure that you receive comprehensive care. Don't hesitate to seek a second opinion if you feel your concerns are not being adequately addressed. Your comfort and well-being are paramount, and there are solutions available to help you find relief.
