My little boy started antibiotics on monday (a week tomorrow) for a tooth abscess caused by a cracked tooth. He went to the dentist on thursday who drained/burst it, to relieve the pain from pressure build up and advised us to continue with amoxiciillin, since it has grown in size again. He is due to go back saturday, hopefully to have it removed. If it's still too swollen, the can't use anasthetic, should the antibiotics have reduced the swelling by now or should we wait a bit longer?
