Amoxicillin / clavulanate
"Taking medication for tooth infection after root canal went wrong. This is my seventh course of antibiotics in a bout three months. Not good! The others were plain old Amoxicillin which hasn't helped at all............

This appears to be helping but with just two tablets left I still have swelling in my gums just below the sinus area. The good news is I have had no side effects apart from diarrhoea and stomach ache on the first day but I think this was due to my taking a load of probiotics which can be hard on the stomach at the start. Halved probiotics to two three times a day and now fine

I am sure the tooth will erupt again in a few days though."
