When this didn't improve within a few days you should have called your dentist. With an abcess, antibiotics normally bring it down totally within a week, but if you see no improvement at all by the 3rd or 4th day always call your doctor. Tell your dentist that you cannot afford the antibiotic she wants you to take and she can find something as good but more affordable for you. This was a horrible thing for you to have endured....I just can't imagine! A tooth infection can go to the brain and you're very lucky this didn't happen. But considering how bad this was/is I would talk to your dentist about a more affordable antibiotic as I feel you need another complete round to make sure all infection is gone. I feel so bad for you and hope this eases up quickly. Take care.
I wen't to a different doctor and they prescribed me amoxicillin. I thought they were the same?
They are somewhat the same, at least amoxicillin derived from penicillin. Amoxicillin though is more powerful and wider range type of antibiotic.
