It usually takes about 2-3 days for the antibiotics to really start being effective.  How large is the swelling and does it interfere in any way?  If it does, I would consider going to the ER to switch antibiotics or drain the swelling.  If its a minor swelling of just the gum area with no problems of any other sort, I would give it another day to see if it improves.

Great.  So whats the next step?  Probably a re-treatment of the root canal I assume.
