Ive had pain in tooth 2nd from eye tooth sine the,ast week of July saw my dentist Aug 9th and he did a root canal and prescribed 500mg Amox. 3Xday.  The pain got worse and Aug 21 he continued root canal and more antibiotics same dosage as previously. This past weekend the pain was so bad, radiating to the ear and head and yesterday n Im insisted tooth be removed. 24 hours later pain still present radiating to ear and head. He has now prescribed a stronger antibiotic which is still to be delivered. Is this normal?  Can this pain be caused by something else?
I think you are going in wrong direction, and it is sinus which is causing ain as every time you poke teeth the sinus gets more infected and radiation to ear eye and other organs is sharing of nerves get X-ray PNS waters view and consul tent specialist to treat instead of unnecessary poking of teeth
