What is Ludwigs angina?

Ludwig's angina is a severe, rapidly progressing bacterial infection of the floor of the mouth and neck, usually starting from a tooth infection (like an abscessed molar) or mouth injury, causing significant swelling, pain, difficulty swallowing (dysphagia), and drooling, and it's a medical emergency because it can quickly block the airway, leading to suffocation. It affects the submandibular, sublingual, and submental spaces, making the tongue rise and the neck firm. Prompt treatment with antibiotics and sometimes surgery is crucial to protect the airway and prevent serious complications.
