<s>[INST] I had damage to my gum in a pocket, and maybe a vein in my gum that bled and was trapped in the gum. It was infected and swelled. After months of antibiotics and not knowing what it was I found it and cleaned it with Hydrogen peroxide. Its doing much better and no more pain but it seems like there is something still producing pus. The periodontist took xrays and says he doesnt know what it is and thought it was just healing. Since then a sliver of bone that was exposed has fallen off, but it keeps seeming like there is still an infection somewhere. What should I do? [/INST] Hellooo...read through your query...accordingly I feel that the puss can be due to periodontal abscess....but nothing to worry...since u got it cleaned...u can do regular brushing twice daily.tongue scraping, use diluted Listerine mouth rinse twice daily, do salt water gargle as many times as possible(min: twice).do continue this for a week. Take antibiotics(Amos+metronidazole)for 5 days if still persists take an opinion of another periodontist(just to know the cause).be cool and calm.hope your benefitted something from this reply.have a healthy day!!! </s>
