Root canal treatment issues?


A few years ago, I had a root canal treatment but did not get a crown.
Recently, during an X-ray examination, it was found that there is inflammation in the gums and the tooth is loose.
At that time, the dentist suggested extracting the tooth and making a bridge or implant, as he believed that making a crown for protection would not last long.
Given this situation, what would you recommend, doctor?

The above situation may be caused by cracks in the tooth itself leading to periodontal infection.
If the crack has extended to the dental floss, it is advisable to extract the tooth.
However, if the crack does not involve the root and the crown structure is still intact, a dental crown may be considered for protection.

When faced with issues related to root canal treatment, particularly when there is inflammation in the gums and mobility of the tooth, it is essential to evaluate the situation carefully. Based on your description, it seems that the tooth in question has undergone significant changes since the root canal treatment was performed. The presence of inflammation and tooth mobility are concerning signs that indicate the tooth may no longer be viable.

In general, root canal treatment aims to save a tooth that has become infected or decayed. However, if the tooth has not been restored with a crown or other protective covering after the root canal, it can become more susceptible to fractures and further decay. The fact that your tooth is now showing signs of inflammation and movement suggests that the structural integrity of the tooth may be compromised, possibly due to a fracture or resorption of the surrounding bone.

In such cases, the recommendation to extract the tooth and consider a dental bridge or implant is often prudent. Here are some key points to consider:
1. Tooth Mobility: If a tooth is mobile, it indicates that the supporting structures (bone and periodontal ligaments) are compromised. This is often a sign that the tooth may not be salvageable, and extraction may be the best option to prevent further complications.

2. Inflammation and Infection: Persistent inflammation in the gums can indicate an ongoing infection, which may not respond well to additional root canal treatment. If the infection has spread or if there is a risk of it affecting adjacent teeth, extraction may be necessary to maintain overall oral health.

3. Restoration Options: After extraction, you have several options for replacing the missing tooth. A dental implant is often considered the gold standard because it mimics the natural tooth root and provides a stable foundation for a crown. A dental bridge is another option, but it requires altering adjacent teeth, which may not be ideal if those teeth are healthy.

4. Long-term Considerations: If your dentist believes that restoring the tooth with a crown would not be effective in the long term, it is essential to heed that advice. A tooth that is likely to fail soon after restoration can lead to additional costs and complications down the line.

5. Consultation with Specialists: If you have concerns about the extraction or the subsequent restoration options, consider consulting with a specialist, such as an oral surgeon or a periodontist. They can provide insights into the best course of action based on your specific dental health and needs.

In summary, given the signs of inflammation and mobility of your tooth, extraction followed by a dental implant or bridge may be the most sensible approach. It is crucial to address these issues promptly to avoid further complications and to ensure that your oral health is maintained. Always discuss your options thoroughly with your dental care provider to make the most informed decision.
