I had a second molar extracted a week ago, followed by a bone graft.  Surgery went well and the extraction site has healed nicely.  2 1/2 days after the procedure, I developed severe pain in one of my front teeth (perfectly healthy tooth) and in part of my jaw, but not near the extraction site.  Called oral surgeon over the weekend and he called in antibiotics just in case there is an infection.  There is no obvious infection.  3 days of antibiotics later, no improvement.   What could be causing this?
Thanks for your query, I have gone through your query. The pain in the tooth can be because of the gum infection or tooth infection. Nothing to be panic, consult an oral physician and get it ruled out. You need to take radiographs like IOP AR to confirm the diagnosis. You need to take a course of antibiotics like amoxicillin and metronidazole combination(if you are not allergic). If it is an infected tooth, you need to get the tooth treated with RCT. If it is a gum infection, you can get the teeth cleaned. I hope my answer will help you, take care.
