When a toothache causes a fever, the cause of the toothache is first treated locally, such as opening the pulp for treatment and rinsing and medication. Systemic symptoms are treated with antibiotics and supportive care.
Toothache can have multiple etiologies, such as acute pulpitis, wisdom tooth pericoronitis, etc. Localized inflammation may spread and cause systemic reactions, such as low-grade fever and malaise. The first step is to find the cause of the disease and control the local inflammation with local treatments such as pulp opening and rinsing.
Meanwhile, oral antibiotics and systemic supportive therapy should be used for systemic symptoms and low fever. Anti-inflammatory and analgesic drugs, such as amoxicillin, metronidazole, ibuprofen, etc., are commonly used clinically. Systemic supportive treatment includes more rest, maintaining fluid balance, and supplementing sufficient calories.
Fever caused by toothache is recommended to consult the hospital in time and receive treatment under the guidance of the doctor. The medication should be prescribed by the doctor.
