Extraction of the second molar and wisdom tooth?


Because all four wisdom teeth have erupted and are misaligned, and the process of their growth has caused gum swelling and pain affecting my ability to eat, I scheduled a dental consultation at the hospital to discuss the extraction of the wisdom teeth after the swelling subsides.
Previously, I had an issue with the lower second molars growing horizontally, but due to the pandemic, the extraction was delayed.
During the recent consultation, the doctor recommended extracting all four wisdom teeth along with the upper and lower second molars, totaling eight teeth.
The reason given by the doctor is that the position of the second molars makes it difficult to clean the first molars, which could potentially affect all three molars.
Therefore, the recommendation is to extract the misaligned second molars to preserve the first molars.
Currently, my mother has concerns about this, fearing that removing eight teeth will have significant future implications.
She hopes that I will only extract the wisdom teeth and wait until the second molars truly affect the first molars before proceeding with their extraction.
I would like to ask if extracting these eight teeth will indeed have a major impact.
Will it necessitate dentures or implants? If I follow my mother's suggestion, could it lead to other issues? I have noticed that most articles discuss the potential problems of not extracting the upper and lower teeth simultaneously, such as overgrowth of opposing teeth and alveolar bone resorption, but I haven't seen much information on whether extracting these teeth together could cause future issues related to chewing, cleaning, aesthetics, etc.

Hello: It is recommended to consult the oral surgery department at a medical center for a second or third opinion, including whether it is necessary to extract all second molars together.
If the opinions of 2 to 3 doctors are consistent, there is less need for hesitation or concern.
However, if there are differing opinions, the patient's preferences should take precedence, as there is currently no urgent need or indication for tooth extraction in your situation.

When considering the extraction of wisdom teeth and second molars, it's essential to understand the implications of such procedures on oral health and overall well-being. Your situation, where all four wisdom teeth have erupted and are misaligned, along with the presence of horizontally positioned second molars, raises valid concerns regarding the recommended extraction of eight teeth simultaneously.

Understanding the Rationale for Extraction:
The primary reason your dentist suggested extracting both the wisdom teeth and the second molars is to prevent potential complications that could arise from their misalignment. Misaligned teeth can lead to difficulties in maintaining oral hygiene, which may result in cavities, gum disease, and other dental issues. Specifically, the second molars can obstruct access to the first molars, making it challenging to clean them effectively. This can lead to decay in the first molars, which are crucial for chewing and overall dental function.

Potential Consequences of Extraction:
1. Immediate Effects:
- Pain and Discomfort: Post-operative pain is common after tooth extractions, but this can be managed with prescribed pain relief medications.

- Swelling and Bruising: These are typical responses to surgical procedures and usually subside within a few days.

2. Long-term Effects:
- Jaw Function: Removing multiple teeth can initially affect your ability to chew and speak. However, most patients adapt quickly, and normal function usually returns as healing progresses.

- Bone Health: Extracting teeth can lead to changes in the jawbone. If teeth are removed, the bone may resorb over time, which can affect the stability of adjacent teeth. However, this is often manageable with proper dental care and, if necessary, bone grafting procedures in the future.

3. Aesthetic Considerations:
- Facial Structure: The removal of teeth can alter the facial profile, especially if multiple teeth are extracted. However, this is often not noticeable after healing, as the remaining teeth shift to fill the gaps.

4. Future Dental Work:
- Need for Prosthetics: While it is not guaranteed that you will need dentures or implants after extraction, it is a possibility if significant bone loss occurs or if the remaining teeth shift dramatically. Regular dental check-ups can help monitor your oral health and address any issues before they become severe.

Addressing Your Mother's Concerns:
Your mother’s apprehension about the extraction of eight teeth is understandable. It is crucial to weigh the benefits against the risks. If the second molars are not causing immediate issues, a conservative approach—removing only the wisdom teeth—might seem appealing. However, delaying the extraction of the second molars could lead to complications that may necessitate more extensive dental work later.

Consultation and Second Opinions:
Before making a final decision, consider seeking a second opinion from another dental professional. They can provide additional insights and may suggest alternative treatment plans, such as monitoring the second molars for changes over time.

Conclusion:
In summary, while extracting eight teeth may seem daunting, it is often done to prevent more significant issues in the future. The decision should be based on a thorough evaluation of your dental health, the potential risks of leaving the second molars in place, and your personal comfort level with the procedure. Open communication with your dentist about your concerns and preferences will help ensure that you make an informed decision that aligns with your oral health goals.
