It is possible to take cephalosporin for toothache, but it is best to clarify the cause of toothache. Clinically, the majority of toothache is caused by bacterial infection, whether it is due to bacterial infection of the hard tissues of the teeth, caused by apical infection and pulpitis, or bacterial infection of the periodontal tissues caused by pericoronitis of the wisdom teeth, all are caused by bacteria, from this point of view, eating cephalosporin and other broad-spectrum antibiotics have an inhibitory effect on bacteria and are certainly effective In this sense, taking broad-spectrum antibiotics such as cephalosporin is certainly effective in inhibiting bacteria. For example, trigeminal neuralgia can also have toothache symptoms, and taking cephalosporin just doesn’t work. Even if the toothache is caused by a bacterial infection, taking cephalosporin is not a cure, and you must go to a professional dentist to treat the cause of the toothache.
