A wisdom tooth infection is typically indicated by several signs and symptoms. Key indicators include severe and persistent pain around the wisdom tooth that may radiate to the jaw, neck, or ear; swelling and redness of the gums around the affected tooth; difficulty opening the mouth widely; fever indicating the infection might be spreading; and bad breath or an unpleasant taste caused by pus or bacterial buildup. Other symptoms may include difficulty chewing or swallowing, jaw stiffness, headaches on the affected side, and pus discharge from the gum near the tooth. If these symptoms are present, it's important to seek prompt dental care to prevent serious complications.
