The dentist does not recommend placing a crown after root canal treatment on a molar?


Hello Doctor, I have a deep cavity in my lower second molar, and during the root canal treatment, I developed two abscesses in the gum behind it.
The doctor mentioned that the tooth has some mobility, which may indicate periodontal disease.
Recently, after completing the root canal treatment, the doctor explained that the gum pocket behind the tooth is relatively deep, and there is concern that if it is not cleaned properly, it may still become inflamed.
They decided not to place a crown, only to fill the tooth.
Additionally, the periodontal disease is not severe enough to require treatment at this time, so it is being left untreated for now.
I am a bit worried about not having a crown on the molar, fearing that it may lead to more serious issues in the future (e.g., accidentally cracking the tooth, which may require extraction or dental implants).
The doctor reassured me that I do not need to worry about these issues and suggested returning for a cleaning in six months.
Should I seek a second opinion from another dentist? I would like to hear your advice.
Thank you.

Hello: If periodontal issues persist after root canal treatment, such as difficulties in cleaning the posterior gingival sulcus leading to inflammation, it may be advisable to consult a periodontist for an evaluation of potential solutions.
Once the periodontal issues are resolved, you can then proceed to place a crown to protect the tooth.

More Info


After undergoing root canal treatment, the decision to place a crown on the affected tooth is often a critical one. Your dentist's advice against placing a crown may stem from several considerations, particularly regarding the health of the surrounding tissues and the overall condition of the tooth itself.

Firstly, it's important to understand that root canal treatment removes the infected or damaged pulp from inside the tooth, which can leave the tooth more brittle and susceptible to fractures. Crowns are typically recommended to provide structural support and protect the tooth from further damage. However, if your dentist has assessed that the tooth is stable and that the surrounding gum tissue is not severely compromised, they may feel that a crown is not immediately necessary.

In your case, the presence of gum issues, such as deep periodontal pockets, can complicate the situation. If the gum tissue is inflamed or if there is a risk of infection due to poor oral hygiene, placing a crown might not be the best option at this time. Crowns can sometimes trap bacteria and food particles, which could exacerbate any existing periodontal issues. Your dentist may be prioritizing the health of your gums and the overall stability of your dental structure over the immediate placement of a crown.

However, your concerns about the potential for the tooth to crack or become further damaged without a crown are valid. Teeth that have undergone root canal treatment can be more prone to fractures, especially if they are located in areas that endure significant chewing forces, such as molars. If the tooth is already showing signs of mobility or if there are concerns about its structural integrity, it may be wise to seek a second opinion from another dental professional. A different dentist may provide additional insights or alternative treatment options that could better address your concerns.

In addition to seeking a second opinion, it is crucial to maintain excellent oral hygiene practices. Regular dental check-ups and cleanings will help monitor the health of your gums and the treated tooth. If your dentist has suggested waiting for six months before reassessing the situation, it is essential to follow their advice while also being vigilant about any changes in your dental health.

If you do experience any pain, swelling, or other concerning symptoms in the interim, do not hesitate to contact your dentist. These could be signs of complications that may require immediate attention.
In summary, while your dentist's decision not to place a crown immediately may be based on a careful assessment of your current dental health, your concerns are valid. Seeking a second opinion can provide peace of mind and ensure that you are making the best decision for your dental health. Remember, maintaining good oral hygiene and attending regular dental visits are key to preventing further complications.
