Dr. Katie To describes a patient with chin swelling from a dead tooth that had root canal treatment. The infected tooth triggered an abscess that released pus nonstop when cut open. Pus is white blood cells attacking bacteria, and it can dissolve bone around the tooth.

Patient have a swelling chin because the tooth had root canals and the tooth is dead and the body attacking it. I have to drain it, and when I cut into it, pus coming out like nonstop. That's what your body doing. What is pus? It's white blood cell that protecting your body and melting the bacteria, melting your bones away. Most root canal teeth don't hurt and pain is rare, and the systemic effect is what matters.
