Can erythromycin be taken for toothache?

When toothache is caused by a bacterial infection that is sensitive to erythromycin, the medication may be taken under medical guidance. However, it should not be used if the cause is non-bacterial or if the patient is allergic to erythromycin. Self-medication should be strictly avoided. It is recommended to seek timely medical evaluation at a hospital, undergo appropriate examinations to determine the underlying condition, and follow professional medical advice for proper management.

Erythromycin is an antibiotic effective only against toothaches caused by bacterial infections, such as acute pulpitis or pericoronitis of wisdom teeth, where inflammation results from bacterial growth. Prior to use, a doctor’s diagnosis is essential to confirm the type and severity of infection. The physician will evaluate factors including the patient's allergy history and liver or kidney function to determine whether erythromycin is appropriate, thus avoiding ineffective treatment or the development of drug resistance due to inappropriate use.

If tooth pain arises from non-bacterial causes such as dentin hypersensitivity or cracked tooth syndrome, taking erythromycin will be ineffective. Moreover, it may adversely affect health due to side effects, such as gastrointestinal discomfort including nausea and diarrhea, or potential liver damage.

In addition, even when erythromycin is indicated, it must be taken strictly according to the prescribed dosage and duration. Do not arbitrarily increase or decrease the dose or discontinue the medication prematurely. If the tooth pain does not improve or worsens during treatment, or if allergic reactions such as rash or difficulty breathing occur, stop taking the drug immediately and seek prompt medical attention to adjust the treatment plan.
