Ive got an abscess on my bottom teeth, 3rd tooth along from the middle ones. It was broken and the dentist started the root canal and filled me in and sent me away till my next appointment. Next day it was painful, I slept most of the day. Day after I noticed that an abscess was forming, went to dentist and was given amoxicillin, 500mg 2 tablets 4 times a day for 5 days. Fine, except I think the abscess is getting slightly bigger, its slightly sore but nothing I would take medication for. Do I need to go back as an emergency tomorrow? (Im in the UK ans it's after 9pm. I can wait till the morning)
