In the case of an impacted mandibular third molar impinging on a second molar, what is the recommended treatment?

When dealing with an impacted mandibular third molar that is impinging on the second molar, the recommended treatment option is to consider the extraction of either the impacted third molar or the adjacent second molar. This approach is justified because the presence of the impacted third molar can contribute to complications such as infection, decay of the second molar, or discomfort.

By extracting the third molar, the source of the impaction is removed, which can alleviate pressure and prevent further damage to the second molar. However, if the second molar is already compromised (e.g., has extensive decay or periodontal issues) and is likely to pose a greater risk if retained, it may be advantageous to extract that tooth instead.

This flexibility in treatment selection allows dental professionals to tailor their approach based on the specific clinical situation, patient history, and overall oral health considerations. The key takeaway is that both teeth are part of the treatment strategy depending on their health and the implications of the impaction.
