<s>[INST] I had an abcess on my tooth took antibiotics and it went away...  I started getting Bad headaches and ear and timple aches on  opposite side. Now the abcess is back and in my right jaw and I think my neck now. I cant open my mouth. Im so scared please help me! [/INST] Thanks for your query, I have gone through your query. The pain, swelling(abscess) and limited mouth opening could be because of the gum infection over the wisdom tooth or any other 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. If the infection is from the other tooth, the tooth has to be treated with RCT or extraction. You can take a course of antibiotics and analgesics like amoxicillin 500 mg and metronidazole 400 mg TID for 5 days (if you are not allergic). I hope my answer will help you, take care. </s>
