I would give it 48 hours for the antibiotics to begin to work. If there is no change by tomorrow, then I would be seen in the ER or perhaps even urgent care. If you are in pain still, then I would be seen. But the swelling may get worse before it gets better. It must be a pretty bad infection. Also rinse your mouth out with salt water and/or 1/2 water 1/2 peroxide. You can also apply a warm compress to the area or a cool compress as well.
