question: Daily aching pain in upper left cheek bone. Had an apicoectomy on number #13 8 months ago after having the root canal reworked twice over the lsat 4 years. Since then, #11 spontaneously died and I've had to have a root canal in that tooth along with #14 and #12. Now, I have no roots in my upper left-side teeth but, I'm still having constant aching to the point where I've been taking ibuprofen daily and sometimes something stronger. According to the dentist x-rays there's no longer any infection and everything is healing fine. Any suggestions to what might be going on?
