I posted recently about this as I was concerned about the short course of antibiotics given by the dentist. He only gave me a 3 day course of amoxicillin for a gum infection and lo and behold they have done absolutely nothing. He has consequently emailed a prescription of metronidazole to the chemist for me to pick up on Monday but again its only 3 days. Last time I had an infection in the same area both antibiotics did nothing and i had to have my wisdom tooth extracted on order for it to settle. What would be the next course of action if metronidazole doesn't work either? Is there something physical the dentist can do to improve my chances of it healing? I'm starting to get quite concerned that I'll just be given more and more antibiotics until I'm ruined :( the amoxicillin have already given me an awful stomach and diarrhoea after only 3 days. Metronidazole is awful so I'd rather not take it if the dentist can do something else instead. I'm starting to get desperate now, it's so painful.
