Last weekend I went to the emergency dentist with a suspected gum infection on the lower right side of my mouth and the dentist gave me a course of Metronidazole to take but said only to take them for 5 days. Obviously my 5 days are up now but I was wondering why I only had to take them for 5 days and not the 7 day course she gave me?

Additional to this, on the lower left side of my mouth I have a bit of a gum flap on my wisdom tooth which has been painful all day and I’m wondering should I continue the Metronidazole?

Thanks in advance 🙂
