Is there a difference between an abcess and an infection in the root? I visited my dentist last Thurs. and he said I have an infected root. He wasn't sure, though, if it was caused by an infected sinus cavity very close to the root. He prescribed Amoxicillan, and after taking only 2 that evening, all of the severe pain in my tooth and jaw were gone within a few hours. I mean this is a tooth that I couldn't even touch with my tongue that day, it hurt so bad. Can antibiotics work that quickly?
Thank you.
