A dental abscess, or tooth abscess, is an accumulation of pus that forms inside the teeth or gums. The abscess typically originates from a bacterial infection, often one that has accumulated in the soft pulp of the tooth.In Spain number of new cases of Tooth abscess diagnosed in 2014 is 4,630 (2,691 males; 1,460 females). Projected number of deaths from Tooth abscess in 2015 is 20 (1,400 males; 1,939 females). In 2015, it is estimated that the risk of an individual dying from Tooth abscess will be 1 in 80.
Diagnosis of a tooth abscess is collectively determined by (1) signs and symptoms reported by the patient, (2) exam and tests that are performed by the dentist, and (3) what is visualized with dental radiographs (X-rays). Future research deals with determination of various host and environmental factors that put an individual at risk for development of dental abscess. Increased reliance on novel molecular techniques has enriched our knowledge of the diverse polymicrobial collection that constitutes a dental abscess.
