Abscess Tooth

An abscessed tooth, also known as a dental abscess, is a localized collection of pus within the tissues surrounding a tooth, typically resulting from bacterial infection. Key clinical points include: 1) It often arises from untreated dental caries, periodontal disease, or trauma to the tooth. 2) Patients may present with severe toothache, swelling, and fever. 3) Diagnosis is confirmed through clinical examination and imaging studies such as X-rays. Etiology involves the invasion of bacteria into the pulp chamber, leading to necrosis and subsequent pus formation. Pathophysiologically, the body responds to infection by sending white blood cells to the site, resulting in inflammation and pus accumulation. Clinically, patients may exhibit tenderness upon palpation, facial swelling, and possible drainage of pus. Typical use cases for this diagnosis code include dental emergencies requiring immediate intervention, such as drainage or root canal therapy.
