I do NOT have pericoronitis or periodontitis...I was treated at the dentist for a crown to replace a filling...there was no decay or infection at the time.  The evening after the treatment my cheek, on my jaw line the same side and area that was worked on, swelled and was very painful.  The gum is not swollen.  The emergency room couldnt figure it out, the dentist couldnt figure it out and the best so far is I am taking antibiotics for three days, but they have not made a difference.  Please help.
Thanks for your query, I have gone through your query. The swelling over the cheek and jaw bone can be because infection in the tooth, since you are telling you went to replace a filling. While crown cutting or tooth preparation, they might have exposed the pulp and that have caused the swelling (cellulitis). The other possible cause can be an allergic reaction to the cement or crown material used. Consult a good oral physician and get it evaluated, take a radiograph to confirm the diagnosis. If I am your treating doctor, I could have suggested you to take a course of antibiotics like amoxicillin and metronidazole combination and an antihistamine like cetirizine. I hope my answer will help you, take care.
