A member asked:
Can a tooth that is cracked and rotten cause a lymph node behind my ear to swell and be a little tender?

Yes, it can: and that is a sign that the infection is starting to spread to your body. This is a sign that you need to see a dentist and get that tooth taken care of, and soon. Good luck to you.

Sure: The infection is spreading. Please see a dentist ASAP.

Yes: Rotten = infection. Lymph nodes are designed to trap pathogens, limiting the spread of infection. Unless the source of infection, the diseased tooth, is addressed, the infection will eventually spread beyond the safeguard, the lymphatic system. Please call a Dentist for care.

Of course: The presence of the bacteria from a rotten tooth alerts your body's defenses (lymph system) and thus your lymph nodes may swell behind the ear.
