See any dentist ASAP: A tooth abscess 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 abscess is a collection of pus that forms in your teeth or gums as a result of a bacterial infection. Dentist will treat a tooth abscess by draining it and getting rid of the infection.
