I am in Malaysia on vacation when I suddenly developed a pain in my teeth. No swelling, no cavities, no bleeding. A throbbing pain in the gum area(lower right jaw). Visited a local dentist today, and they were not too sure as well. Prescribed Metrogyl 200 capsules 2, thrice a day and Betamox 500 capsule 1, thrice a day. Is this an effective medication, asking since they were not too sure as well after examining me.
