<s>[INST] hello, my gum is swollen on the last part near to my left molar. it was swolen i think because i usually chew something there. its the second day and its getting worse. ive taken amoxicillin and ibuprofen and the pain goes away for sometime but it will come back and still doesnt get better. please help. [/INST] Thanks for your query, I have gone through your query. The pain, swelling and limited mouth opening could be because of the gum infection over the wisdom tooth (periodontal infection leading to space infection). Consult an oral physician and get a radiograph done to rule the amount of space present for the tooth to erupt if space is there for the tooth to erupt then the gum covering over the wisdom tooth can be removed. If the space is not available then you have to get the wisdom tooth removed. Meanwhile you can take a course of antibiotics like metronidazole 400 mg TID along with amoxicillin 500 mg and ibuprofen for 5 days (if you are not allergic). Do saline gargling. I hope my answer will help you, take care. </s>
