antibiotic tablets metronidazole 200mg

I have had tooth problem last week and the government dentist in my local dental clinic found nothing wrong with my molar tooth. An x-ray was taken and still, no obvious decay or crack detected. So, the young Malay dentist prescribed a course of antibiotic Metronidazole 200mg, for 5 days course. It cured my toothache (whenever I bit something hard) and in the same it cured my cough. I think mild antibiotic is good, if taken accordingly.

Roxithromycin 150 mg for 4 days course , for kid, 1 tablet each time twice a day.
