Can impacted wisdom teeth cause swollen lymph node in neck? i noticed it and i don't know why it's there and i'm worried. going to the dr later this month?

An impacted wisdom tooth without infection should not cause a reactive lymph node. However, reactive lymph node is common so there is nothing to concern in the mean time, please patiently wait for your appointment. Take care and good luck!

I think so, especially if the area surrounding the teeth is inflamed. Rinse area with peroxide, and keep area very clean. Food debris can cause infection. Get teeth out.

Yes. Please see an Oral and Maxillofacial Surgeon for differential diagnosis and appropriate treatment.
