<s>[INST] i have had an abcess in my tooth for about 3 days now. i have already gotten meds(amoxicillin) and have been taking it for almost a day now. it feels like it may be getting worse. i have taken amoxicillin before for the same thing and it yielded much better results, has it just not been long enough yet, or are they not working as intended? [/INST] Thanks for your query, I have gone through your query. Taking Only amoxicillin will not be effective in abscess cases. You can take a course of antibiotics like amoxicillin 500 mg with metronidazole 400 mg TID for 5 days (if you are not allergic). The medicines take 1-2 days to bring down the infection. Do saline gargling. Once the infection comes down, then you can get the tooth treated with RCT or extraction. I hope my answer will help you, take care. </s>
