<s>[INST] I am in extreme pain in my lower right molar (the molar that is the farthest back).  I noticed a little swelling in the gums in that area so I went to the ER in the middle of the night, as the pain was unbearable. The ER doctor prescribed me oxycodone and clendamycin.  I just started taking these medications today, but the pain remains very intense.  When will the clendamycin start having some positive effect? [/INST] Thanks for your query, I have gone through your query. The pain and swelling could be because of the gum infection around your wisdom tooth it is called peritonitis. You can take penicillin with metronidazole is more effective than clindamycin and clindamycin costly. The permanent solution for your problem is you need to get the overgrown gums around the tooth removed or the tooth. If there is no sufficient space for the tooth to erupt, then it has to go for extraction. Do saline gargling. I hope my answer will help you. Take care. </s>
