Jaw Swelling

Jaw swelling can range from a minor cosmetic concern to a sign of serious infection or disease. The swelling may appear on one or both sides of the face, developing suddenly or gradually over time. Common causes include dental infections, salivary gland problems, and trauma, but jaw swelling can also indicate systemic conditions or tumors. The location, timing, and associated symptoms provide important clues to the underlying cause. While some cases resolve with simple treatments, others require urgent medical attention to prevent complications such as airway obstruction or spreading infection. Understanding when jaw swelling is an emergency helps ensure timely and appropriate care.
