Q. I’m 36yrs and still have a lower right baby tooth which has been giving me toothache so my dentist has put a temp dressing in and given me antibiotics to settle the infection, this happend 4 days ago and i have a very tender jaw line and pain which runs up to my ear when i open my mouth to eat. I have never experienced anything like this and i hav been getin headaches in a morning, is there a reason for this.,
