Swollen lymph nodes: Those nodes can occur with a running nose and many times when a child teethes his nose will run. You neednt be concerned.

Reactive lymph nodes: In that location would more likely be from scalp lesions that became inflamed, some systemic viral illnesses can cause "shotty" lymph nodes in different areas (groin, armpits, etc), but teething does not.

Lymph nodes filter : The primary symptoms of teething are slobbering, pain, chewing, and irritability. If your baby has swollen lymph nodes along with the above its possible your baby has an infection of some sort along with teething. Children can have lymph node swelling especially when the bodies immune system is fighting the "bugs" they come in contact with. If there is high fever bring her in to the doctor.
