Infected wisdom tooth removed 6d ago. achey jaw/ear pain ystrday. stitches out today--no dry socket but he put med pack anyway. should i be concerned?

Any fevers?: if its just pain that is probably par for the course. As long as you are not having fevers you should be fine but obviously follow up with the dentist/surgeon as needed

Ask your dentist: it seems as you dentist has the situation under control,wisdom tooth still causing pain after a week can be an issue, if the pain is tapering of I would say that you are on you way to a good recovery, but this should be best addressed by your dentist. Good luck.

Socket prevention: Your dentist packed the medical dressing that promotes healing. Discomfort and other symptoms should continue to improve over the next few days. Complete healing typically goes smoothly and generally takes about 10 to 14 days.
