Tooth Root Residue: Options for Dental Correction and Concerns - Dentistry

Root remnants


Doctor, I have four molars that have cavities, causing my adjacent teeth to tilt forward over time, resulting in a slight indentation on my right cheek.
I often bite my mouth, and my healing ability seems poor.
My upper front teeth are slightly misaligned, leaning towards the right.
I have already had an occlusal splint made and am waiting for three weeks.
Recently, I started orthodontic treatment after a dental examination.
The doctor assessed that I would need four bone screws for the correction in front of the four molars.
The doctor mentioned that the root of the lower left molar was not completely extracted initially, and I need to decide whether to place a dental implant or to extract the root and fill it with bone graft material before proceeding with the orthodontic treatment.
However, based on my periodontal condition, it may not be possible to pull the teeth together, and I might need to get a dental implant instead.
The root appears to be in stable condition without any significant changes.
The doctor indicated that I seem to have low bone density, which might affect the stability of the orthodontic treatment.
Although the teeth can be aligned, they may not remain stable.
The roots are deeply embedded and integrated with the bone, which I don't fully understand—does that mean the teeth can fuse with the bone?
How should I make a decision regarding this? If I extract the root and then proceed with orthodontics, but my periodontal condition and tolerance do not meet expectations, I would have to get a dental implant.
Would I have to endure the pain of having the root extracted? If I extract it, will the resulting cavity filled with bone graft material become loose? If I choose not to extract and instead correct the alignment of the back teeth and place an implant later, will retaining the root cause future issues? Could it lead to further dental work if the root eventually develops decay?
After discussing with the doctor today, I returned home with these questions.
Doctor, when a physician asks me to make a choice, I feel unable to decide due to my lack of understanding and the fear that arises from it.
How can I determine whether the doctor has experience with cases like mine, or if I should seek a second opinion, even though the occlusal splint has already been made?

Hello, I think it would be best for you to wear the occlusal splint for at least three months to allow the joint to relax.
After ensuring there is no malocclusion and you are not frequently biting your cheeks, you can proceed with orthodontic treatment to align your teeth.
If there are any remaining roots, they should be extracted first.
Closing the space or bone grafting is quite specialized, so please discuss this with your dentist or consult another orthodontic specialist.
Wishing you health and safety.

Sincerely,
Dr.

When dealing with the complexities of dental treatment, particularly in cases involving residual tooth roots and orthodontic corrections, it is essential to understand the implications of each option available to you. Your situation involves several factors, including the condition of your remaining tooth roots, the alignment of your teeth, and the overall health of your gums and jawbone.

Firstly, it is important to clarify what is meant by "tooth roots." The roots of your teeth are embedded in the jawbone and are crucial for the stability of the teeth. When a tooth is extracted, the root is typically removed, but in some cases, remnants of the root may remain. This can lead to complications, especially if the root is infected or if it affects the alignment of surrounding teeth.

In your case, the dentist has identified that one of your lower molars has a root that was not completely extracted. This can pose challenges for orthodontic treatment. If the root is left in place, it may interfere with the movement of adjacent teeth during orthodontic adjustments. Additionally, if the root is infected or if there is insufficient bone density around it, this could lead to further complications down the line, including pain or the need for additional treatments.

The options presented to you include:
1. Extraction of the Residual Root: This would involve surgically removing the remaining root and possibly augmenting the bone with grafting material (bone powder) to ensure that the area heals properly and is stable for future orthodontic work. While this option may seem daunting, it is often necessary to ensure that the orthodontic treatment is successful and that the surrounding teeth can be properly aligned.

2. Retaining the Root and Proceeding with Orthodontics: This option may seem less invasive, but it carries risks. If the root is not causing any immediate issues, it might be possible to proceed with orthodontic treatment without extraction. However, there is a chance that the root could lead to complications later, such as infection or misalignment of the teeth, which could necessitate further procedures.

3. Consulting a Specialist: Given the complexity of your case, seeking a second opinion from an orthodontic specialist or a periodontist may provide you with additional insights. They can evaluate your specific situation and help you understand the potential outcomes of each option.

4. Understanding Your Concerns: It is completely normal to feel apprehensive about dental procedures, especially when they involve surgery or the potential for pain. Your fears may stem from a lack of understanding of the procedures and their implications. It is crucial to communicate openly with your dentist about your concerns. A good dentist will take the time to explain the procedures, the risks involved, and the expected outcomes.

5. Evaluating the Dentist's Experience: If you feel uncertain about your dentist's experience with cases similar to yours, it is reasonable to seek a second opinion. You can ask your dentist about their experience with similar cases or look for reviews and testimonials from other patients.

In conclusion, the decision regarding whether to extract the residual root or retain it while proceeding with orthodontic treatment is significant and should be made with careful consideration of all factors involved. It is essential to weigh the potential risks and benefits of each option, seek further consultation if necessary, and ensure that you feel comfortable and informed about your decision. Remember, your oral health is paramount, and taking the time to make an informed choice will ultimately lead to better outcomes.
