Docs, could a dental infection spread to your jawline without you knowing?

Yes...: A dental infection from a tooth can spread to the jaw without any immediate symptoms. It is usually from a chronic, low grade infection secondary to decayed and broken down teeth. Dental radiographs will usually show the abscess.

See a dentist ASAP: A tooth infection won't go away without treatment and the infection may spread to your jaw, cheeks, sinus and to other areas of your head and neck. A dental infection is a collection of infectious bacteria in your teeth or gums. Dentist will treat a tooth infection by treating the cause and getting rid of the infection.
