Denture Pain: When to Seek Root Canal Treatment - Dentistry

Dentures pain


Hello, doctor.
I would like to ask about dental prosthetics causing pain.
One clinic said that the tooth root is infected with bacteria and requires root canal treatment and a new prosthesis.
Another clinic mentioned that there was originally a root canal treatment, but it was not thoroughly cleaned.
They suggested focusing on oral hygiene and monitoring the frequency of pain episodes; if they become more frequent, then a redo of the root canal treatment and prosthesis would be necessary.
I'm not sure which one is correct.
Thank you.

If the tooth root is infected by bacteria, it may be due to an infection of the periodontal tissue or an infection at the root apex.
An infection at the root apex is caused by inflammation and necrosis of the nerves within the root canal.
If root canal treatment has already been performed, the infection at the root apex may improve.
However, if there is still an infection at the root apex, it may be necessary to consider retreatment of the root canal.
It is recommended to consult a dentist for further evaluation and treatment.

When it comes to understanding denture pain and the potential need for root canal treatment, it's essential to consider several factors that can contribute to discomfort in the area of a treated tooth. Based on the information you've provided, it seems you have received differing opinions from two dental professionals regarding the cause of your pain and the appropriate course of action.

Firstly, let's clarify what root canal treatment entails. Root canal therapy is performed to remove infected or damaged pulp tissue from inside a tooth, which can be caused by deep decay, repeated dental procedures, or trauma. After the pulp is removed, the inside of the tooth is cleaned, disinfected, and then filled with a material to seal it. If the tooth has previously undergone root canal treatment but is still causing pain, it may indicate that the infection has persisted or that there are complications such as incomplete cleaning of the root canals.

In your case, one dentist suggests that the root may be infected and requires root canal treatment, while the other believes that the initial treatment may not have been thorough enough and recommends monitoring the situation. Both perspectives have merit, but the best course of action depends on a thorough clinical evaluation and possibly additional diagnostic imaging, such as X-rays or a cone beam CT scan, to assess the condition of the tooth and surrounding structures.

Here are some key points to consider:
1. Infection and Symptoms: If there is an infection in the root canal system, symptoms may include persistent pain, swelling, or sensitivity to pressure. If you notice that the pain is becoming more frequent or severe, this could indicate that the infection is worsening, and prompt treatment is necessary.

2. Previous Root Canal Treatment: If the tooth has had a previous root canal treatment, it is possible that not all canals were adequately cleaned or that new decay has developed. This could lead to reinfection, which may require retreatment.

3. Denture Fit and Pain: If you are experiencing pain while wearing dentures, it could also be related to the fit of the dentures rather than the tooth itself. Poorly fitting dentures can cause irritation to the gums and underlying bone, leading to discomfort. It's essential to ensure that your dentures are properly adjusted and fitted.

4. Oral Hygiene: Maintaining good oral hygiene is crucial, especially after dental procedures. Regular brushing, flossing, and dental check-ups can help prevent complications and ensure that any issues are addressed promptly.

5. Monitoring Symptoms: Keeping track of when the pain occurs, its intensity, and any other accompanying symptoms can provide valuable information to your dentist. If the pain becomes more frequent or severe, it may warrant a more immediate evaluation.

In conclusion, both dentists have provided valid points regarding your situation. If you are experiencing ongoing pain, it is advisable to seek a second opinion from an endodontist, a specialist in root canal treatment, who can provide a more detailed assessment of your tooth's condition. They can determine whether retreatment is necessary or if other interventions, such as adjusting your dentures, are needed. Ultimately, addressing the root cause of your pain is crucial for your overall dental health and comfort.
