Tooth root treatment is also called pulpitis. Here the tooth nerve is inflamed, causing the entire tooth to hurt and the pain often stealing into the jaw. Further symptoms are therefore headache or fever.
An abscess that appears in the oral cavity, i.e. a cavity filled with pus, often occurs as a result of inflammation in the oral cavity. It can have life-threatening consequences if, for example, bacteria spread from there via the veins to the brain.
