What causes fever due to toothache?

Fever caused by toothache is usually due to inflammation or infection in the oral cavity. Specifically, this condition may be triggered by the following factors: 1. Periodontitis: Inflammation of periodontal tissues caused by dental plaque. When the inflammation becomes severe, it may lead to systemic symptoms, including fever. 2. Pericoronitis of wisdom teeth: Inflammation of soft tissues surrounding the crown of a partially erupted or impacted wisdom tooth, which may cause fever and other systemic symptoms. 3. Pulpitis: Inflammation of the dental pulp, typically caused by dental caries or trauma. The inflammatory response may disrupt the body's temperature regulation center, leading to fever. In addition, other oral conditions such as periodontal abscesses may also cause tooth pain accompanied by fever. When experiencing both tooth pain and fever, it is recommended to seek timely medical attention to identify the exact cause and receive targeted treatment as prescribed by a healthcare professional, thereby relieving pain and controlling the infection.
