A tooth abscess is a collection of infected material (pus) in the center of a tooth. It is due to bacterial infection. A tooth abscess is a complication of tooth decay. It may also occur when a tooth is broken or chipped. Openings in the tooth enamel allow bacteria to infect the center of the tooth (the pulp). Infection may spread from the root of the tooth to the bones supporting the tooth. The estimated 5-year prevalence of people in China living with Tooth abscess is 7.4 per 100,000. Total prevalence rate for both sexes in China is 7.9 per 100,000. Prevalence rate for men and women 6.9 and 6.2 per 100,000 respectively in China.
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.
