hi i just wondered if there was any dentists on here who could give me some advice?>.......i had a back top tooth out on monday and i ended going back to dentist yesterday because i was in lots of pain... she said it was infected and it is quite common....is it common? she never gave me any antibiotics as i am on some already for a water infection... so how long will it take to heal? if any one could give me some general advice pls that would be great?
