Cefradine capsule can treat toothache, but it should be noted that cefradine capsule may not necessarily treat the root cause of toothache, because toothache often has certain etiology, it may be tooth decay, it may be gingivitis and periodontitis, all of which may cause toothache. Cephalosporin is an antibiotic, which can indeed kill bacteria, but in the case of toothache if the primary focus is not removed, such as tooth decay, the decayed part is not removed, and periodontal disease does not remove the plaque and calculus of the periodontium, the condition may persist recurrently. Oral medication alone cannot completely cure the toothache, and it is necessary to go to a professional dental institution with oral treatment in order to treat the toothache completely.
