the Risks of Retained Tooth Roots After Dental Treatment - Dentistry

Root remnants


Hello Dr.
Huang, about six years ago, I had an accident that resulted in the fracture of my fourth tooth from the front on the right side.
After consulting with a dentist, the fractured tooth was treated, and the adjacent teeth were reduced in size to create a dental bridge.
However, the fractured tooth still has residual root remaining (inside the tooth).
I would like to ask: 1.
Could this pose any health risks? 2.
What is the significance of the remaining root left by the dentist? Thank you!

Hello:
1.
A fractured tooth that has undergone complete root canal treatment and has healthy periodontal status, along with the patient maintaining proper oral hygiene using dental floss and interdental brushes, should not pose any issues.

2.
The dentist may leave the tooth root to prevent alveolar ridge resorption after extraction, which could lead to aesthetic concerns.

Wishing you safety and health,
Dr.
Huang Chih-Cheng, Director of Dentistry, Taoyuan Hospital, Department of Health.

Hello! Thank you for your inquiry regarding the implications of retained tooth roots after dental treatment. This is an important topic, especially for those who have undergone significant dental procedures such as root canal treatments or extractions.

1. Potential Health Risks of Retained Tooth Roots: Retained tooth roots can pose several risks to your oral health. Firstly, if a root fragment is left behind, it can become a site for infection. The body may react to the foreign material, leading to inflammation or the formation of a cyst around the root. This can cause pain, swelling, and even lead to further complications if bacteria proliferate in that area. Additionally, retained roots can interfere with the alignment of surrounding teeth and may contribute to bite issues over time. If the root is not properly sealed or if there are remnants of infection, it could also lead to complications in adjacent teeth, potentially necessitating further dental interventions.

2. Significance of Leaving Tooth Roots: The decision to leave a tooth root in place often depends on several factors, including the condition of the surrounding bone, the root's proximity to vital structures (like nerves or sinuses), and the overall health of the patient. In some cases, if the root is deemed non-infectious and stable, the dentist may choose to leave it in place to avoid the risks associated with surgical removal, which can include damage to nearby teeth or nerves. However, this decision should be made with careful consideration and ideally, a thorough discussion between you and your dentist about the potential risks and benefits.

In your specific case, since you mentioned that the root is located on the inner side of the tooth and has been there for six years, it would be wise to have a follow-up consultation with your dentist. They may recommend imaging studies, such as X-rays or a cone beam CT scan, to assess the condition of the retained root and the surrounding bone. This will help determine if any action is necessary, such as monitoring the root or considering its removal if it poses a risk.

Furthermore, if you experience any symptoms such as pain, swelling, or changes in the surrounding gums, it is crucial to seek dental care promptly. Regular check-ups will also help monitor the situation and ensure that any potential issues are addressed early.

In conclusion, while retained tooth roots can sometimes be managed without immediate intervention, they do carry potential risks that should not be overlooked. Open communication with your dental care provider is essential to ensure that your oral health remains a priority and that any necessary actions are taken to mitigate risks associated with retained roots. Thank you for your question, and I hope this information helps clarify your concerns!
