The ENT dr prescribed antibiotic for ear pain
. He has not told you what was the problem in the ear.The dentist has diagnosed it as infected tooth. So after a course of antibiotic, after pain subsided Root canal Treatment
was done not followed by a Cap on that tooth. The ear pain might have been a referred pain
from the tooth. OK. So far every thing is fine. Now your problem is intolerable pain and swelling and you are put on IV antibiotic
. The most probable reason is blocked root canal infection of that particular tooth. So once pain subsides consult dentist
and that tooth to be removed (tooth extraction). That will avoid the recurrence of pain.
