I had a root canal in one of my lower molars some years ago, and recently the gum around it became inflamed. I went for my normal check-up and the dentist said that it was infected and prescribed antibiotics (I finished the prescribed course). She also told me to brush three times a day. I went back the next week, as the filling fell out of it, and she said that it was looking better, re-filled the tooth and recommended Corsodyl for a couple of weeks. I followed her advice, and continued with the Corsodyl, and things did seem to improve, but as soon as I stopped using it, the gum started to swell again. I noticed on the bottle that a month's course was recommended for gum disease, so thought that maybe I hadn't used it for long enough to completely knock the infection out. I have now been using it for a further three weeks, and things always seem okay in the morning, but the gum swells up again by evening. There is also a dull ache at times. None of these are pretty dramatic symptoms - not even bothersome if I am honest, but I am just worried that there may be an infection that needs dealing with, and I am not feeling anything because the tooth has had a root canal. Is that possible, or am I over-worrying? There is no real pain, just this slightly inflamed gum in the evening - although I am worried that when I stop using the mouthwash, things will worsen. She also x-rayed the tooth, to check that it had had a root canal - so, wouldn't anything really problematic show up on that?
I also would prefer not to take more antibiotics, as I am breastfeeding and had to take them after my baby was born, so she has already been exposed to two doses!
