Can I Get a Crown on My Tooth After Root Canal Treatment?

Root canal issues

I had a root canal treatment on my tooth a year ago, but I haven't gotten a crown yet.
That tooth feels tight.
Later, I had an X-ray, and the doctor said my nerve was resected more than 3mm.
They can only try to remove the gutta-percha, but there's a risk it could break off inside the root.
The doctor also mentioned that the only option might be to surgically remove the entire tooth if it becomes problematic.
Can I go ahead and get a post and crown placed on it since it doesn't hurt right now? What would happen if the excess gutta-percha is not removed? Thank you.
🙏

Dear Ms.
Chen,
Hello! As mentioned, if there is no pain, you can first proceed with a dental crown to protect the tooth and prevent it from fracturing.
The gutta-percha (GP) can be left undisturbed for now.
If, after several years, any adverse reactions occur, such as swelling, we can then consider surgical removal of the root portion.
Currently, if we were to remove the GP, it would likely require the expertise of an endodontist.
Teeth are very valuable, so we should try to preserve them as much as possible!
Thank you! Wishing you safety and health!
Sincerely,
Dr.
Huang Ting-Fang, Dentistry

More Info

After undergoing root canal treatment, it is generally advisable to place a crown on the treated tooth to provide adequate protection and restore its function. The tooth that has undergone root canal therapy is often more brittle and susceptible to fractures, especially if it is a molar, which bears a significant amount of chewing force.
In your case, since the root canal treatment was performed a year ago and you have not yet placed a crown, it is important to consider the current condition of your tooth. The fact that your dentist noted that the nerve was removed more than 3mm beyond the apex of the root indicates that there may be some complications associated with the treatment. If the filling material (GP, or gutta-percha) is extending beyond the root tip, it could potentially lead to issues such as:
1. Infection: If the GP is not properly sealed at the apex, it could allow bacteria to enter and cause reinfection, leading to pain and further complications.

2. Fracture Risk: An unprotected tooth is at a higher risk of fracturing, especially under the pressure of chewing.

3. Need for Surgical Intervention: If the GP is not retrievable without risking fracture or damage to the root, you may need to consider surgical options, such as an apicoectomy, where the tip of the root is removed along with the infected tissue.

Regarding your question about placing a crown directly without removing the excess GP, it is technically possible to do so, but it is not advisable. If the GP remains in the canal and is not properly sealed, the risk of complications increases significantly. The crown may provide some protection, but it will not address the underlying issue of the excess GP, which could lead to future pain, infection, or even the need for extraction if the situation worsens.

If your tooth is currently asymptomatic, it may seem tempting to proceed with the crown, but it is crucial to weigh the potential risks. It is highly recommended to have a thorough discussion with your dentist about the implications of leaving the GP in place and the potential need for further treatment. If your dentist suggests that the GP could break off during removal, it may be worth seeking a second opinion from an endodontist, who specializes in root canal treatments and can provide more insight into the best course of action.

In summary, while you can technically place a crown on your tooth after root canal treatment, it is essential to ensure that the tooth is in optimal condition to avoid future complications. Addressing any issues with the GP before crowning is crucial for the long-term health of your tooth. Always consult with your dental professional to make an informed decision that prioritizes your oral health.
