Acute lymph node enlargement in the jaw usually resolves in a week if it is caused by an infection, but may not resolve in a lifetime if it is caused by chronic lymphadenitis or lymphoma. There are two main types of lymph node enlargement, inflammatory lymph node enlargement of the jaw and tumor lymph node enlargement of the jaw. Inflammatory lymph node enlargement of the jaw is usually caused by infection. Acute lymphadenitis usually shrinks within a week after the infection is well controlled, but some patients may have abscesses or have poor healing ability, which prolongs the healing time. Chronic lymphadenitis of the jaw is difficult to cure and requires long-term treatment with antibiotics such as amoxicillin and cefaclor. Tumor lymph node enlargement of the jaw cannot be cured on its own and requires anti-tumor treatment as prescribed by the doctor.
