Can a Broken Tooth Root in Dentures Be Saved? Expert Insights - Dentistry

dentures for molars


Is it necessary to extract a molar if an X-ray shows a fracture between its two roots? The front teeth have only one root; can't a molar be reconstructed with two roots for a new prosthesis? My family dentist suggested waiting until the prosthesis falls out before extracting it, but I sometimes feel pain similar to that of a cavity.
The molar and the small front tooth are connected by the prosthesis, so is the idea to give the molar some time? Is it really impossible to save a molar that has split into two roots? Is modern microscopic root canal treatment effective for consulting on fractured teeth?

Dear Miss DuoDuo,
Hello! The level of medical care is advancing rapidly, and dentistry has also made significant progress! Regarding the question of whether a fractured root needs to be extracted, it primarily depends on whether the tooth has two roots, the amount of surrounding bone, whether the root is mobile, and if there are any lesions at the root apex.
A comprehensive assessment is necessary to make a decision! As for microscopic root canal treatment for cracked teeth, it can certainly be beneficial! Please communicate more with your dentist! Thank you! Wishing you safety!
Sincerely,
Dr.
Huang Ting-Fang, Dentistry

When it comes to a broken tooth root in dentures, particularly in the case of a molar with two roots that has fractured, the situation can be quite complex. The decision to extract the tooth or attempt to save it depends on several factors, including the extent of the damage, the overall health of the surrounding tissues, and the patient's personal circumstances.

Firstly, it is essential to understand that if a tooth root is fractured, especially in a denture-supported tooth, it can lead to complications. The integrity of the tooth structure is crucial for maintaining proper function and aesthetics. If the fracture is severe, it may compromise the tooth's ability to support the denture effectively, leading to pain, discomfort, or further dental issues.

In your case, since you mentioned that the X-ray shows a fracture between two roots, it is essential to assess whether the remaining tooth structure can support a new restoration. If the fracture is clean and the surrounding bone and gum tissue are healthy, there may be a possibility of saving the tooth through advanced dental procedures. However, if the fracture is extensive and involves the root canal system, it may not be feasible to retain the tooth.

Microscopic root canal therapy has advanced significantly and can sometimes save teeth that were previously deemed unsalvageable. This technique allows for a more precise cleaning and sealing of the root canal system, which can help prevent further infection and promote healing. However, the success of this treatment largely depends on the specific nature of the fracture and the condition of the tooth.

If your family dentist has suggested waiting until the denture falls out before proceeding with extraction, it may be a strategy to avoid unnecessary procedures while monitoring the situation. However, if you are experiencing pain similar to that of a cavity, it is crucial to address this promptly. Pain can indicate that the fracture is affecting the pulp or surrounding tissues, which could lead to infection or abscess formation.

In terms of whether a new denture can be formed with only one root, it is important to note that molars typically require a stable foundation for proper function. If one root is compromised, the remaining root may not provide adequate support for a new denture. In such cases, extraction may be necessary to prevent further complications.

Ultimately, the best course of action is to consult with a dental specialist, such as an endodontist or a prosthodontist, who can provide a thorough evaluation and discuss potential treatment options. They can assess the fracture's severity, the health of the surrounding tissues, and your overall dental health to determine whether saving the tooth is a viable option or if extraction is the best path forward.

In conclusion, while there may be options to save a broken tooth root in dentures, the decision should be made based on a comprehensive evaluation by a dental professional. If you are experiencing pain or discomfort, it is advisable to seek immediate dental care to prevent further complications. Regular check-ups and open communication with your dentist are key to maintaining oral health and addressing any issues as they arise.
