Should You Remove Your Lower Left Second Molar? Expert Insights

Extraction of the lower left second molar?

The dentist recommended the extraction of the lower left wisdom tooth and the second molar, stating that since there is no chewing function, the removal of these two teeth would not affect the first molar (I will also gradually have the other wisdom teeth extracted in the future).
The dentist did not suggest whether I would need dentures or implants after the extraction.
I would like to ask: Is it advisable to extract the second molar? Since the dentist did not mention any need for implants or similar procedures afterward, if I do nothing after the extraction, what impact will it have on the other teeth?

Dear Miss Irene,
Generally speaking, the second molars are not extracted unless there is severe decay or periodontal disease.
It would be advisable to discuss this with your dentist.
If extracted, the upper left second molar may migrate down into the alveolar bone.
Take care and wishing you all the best!
Sincerely,
Dr.

More Info

When considering the removal of your lower left second molar, it's essential to weigh the potential benefits and drawbacks of the procedure. Your dentist's recommendation to extract the second molar and wisdom tooth is likely based on several factors, including the current health of those teeth, their position, and their functional role in your mouth.

Reasons for Extraction
1. Lack of Function: If the second molar is not contributing to your chewing function, its removal may not significantly impact your overall oral function. Dentists often recommend extraction when a tooth is deemed non-functional or when it poses a risk of future complications.

2. Preventive Care: Extracting teeth that are problematic or at risk of decay or infection can prevent more severe issues down the line. This is particularly true for wisdom teeth, which often become impacted or crowded.

3. Alignment and Space: Removing teeth can sometimes help in aligning the remaining teeth, especially if there is overcrowding. This can lead to better oral hygiene and potentially reduce the risk of periodontal disease.

Potential Consequences of Extraction
1. Shifting of Teeth: One of the primary concerns after tooth extraction is the potential for adjacent teeth to shift into the space left by the extracted tooth. This can lead to misalignment and bite issues over time.

2. Bone Loss: The jawbone can begin to resorb after a tooth is removed, which may affect the structural integrity of the jaw over time. This is particularly relevant if you are considering future implants or other restorative work.

3. Impact on Bite: Depending on the position of the extracted tooth, there may be changes in your bite. This can lead to discomfort or issues with chewing if not properly managed.

Recommendations Post-Extraction
1. Monitoring: After the extraction, it’s crucial to monitor how your remaining teeth adjust. Regular dental check-ups will help ensure that any shifting or alignment issues are addressed promptly.

2. Consideration for Implants: While your dentist has not suggested immediate replacement options like implants or dentures, it may be worth discussing these options for the future. If you decide to replace the extracted tooth, implants can provide a stable solution that mimics the function of natural teeth.

3. Oral Hygiene: Maintaining excellent oral hygiene is essential, especially after tooth extractions. This includes regular brushing, flossing, and possibly using an antibacterial mouthwash to prevent infection.

4. Dietary Adjustments: After the extraction, you may need to adjust your diet temporarily to accommodate healing. Soft foods are typically recommended immediately following the procedure.

Conclusion
In summary, the decision to extract your lower left second molar should be made in consultation with your dentist, considering your specific dental health and future plans for your oral care. While the extraction may not have immediate adverse effects, it is essential to be proactive about monitoring your dental health and considering future restorative options if necessary. Regular follow-ups with your dentist will help ensure that your oral health remains optimal after the extraction.
