I had an upper back molar extracted 2 days ago because it had an abscess. It was horribly painful and I made an emergency appointment with a dentist that I didn't entirely trust because I needed some immediate relief. The dentist's office was kind of dirty and a little seedy. The healing process seems to be going fine, however, I'm concerned because the dentist didn't prescribe me with any antibiotics. I thought this was standard procedure when you get a tooth extracted because of an abscess? I'm concerned that he didn't clean out the wound and the abscessed area well enough and that I don't have any antibiotics to ensure that I don't get an infection. What are the symptoms of an infection from where a tooth was extracted? Should I trust this dentist although he didn't give me antibiotics?
