Why is it important to assess lymph nodes in a dental exam?

Assessing lymph nodes during a dental examination is crucial primarily because it helps identify signs of infection. Swollen or tender lymph nodes can indicate the presence of localized or systemic infections, including dental infections such as abscesses, periodontal disease, or even more widespread conditions like viral or bacterial infections. This information is vital for diagnosing any underlying issues and determining the appropriate treatment.

In addition, changes in lymph node size, consistency, or tenderness can also hint at other health concerns, including malignancies or systemic diseases. Therefore, performing a detailed lymph node assessment is an integral part of a comprehensive dental examination, ensuring the clinician can detect potential health risks early and manage them effectively.
