What conditions might cause pain in the jaw and swollen lymph nodes in the neck?

Reviewed by Yoshinori Abe, MD

Jaw pain accompanied by swollen lymph nodes in the neck may indicate several underlying conditions, most commonly submandibular swelling or Ludwig's angina—a serious bacterial infection of the floor of the mouth. Other potential causes include dental infections, salivary gland issues, tonsillitis, or viral illnesses like mononucleosis.

Because these symptoms can range from mild to medically urgent, identifying the cause early is critical. Ludwig's angina, in particular, can progress rapidly and affect breathing if left untreated. Understanding what's driving your symptoms helps you decide whether home care, a dentist visit, or urgent medical attention is needed.
