I Have Severe Dental Pain. My Dentist Has Replaced My

I have severe dental pain. My dentist has replaced my fillings with a dressing but three days on it is no better and now the side of my chin where the pain is, has swollen. I have been taking the max of painkillers I googled... 60mg codiene 8 per day; 400mg ibuprophen 6 times a day and 500mg amoxicillin that I had in my medicine cabinet at home 1 X a day for five days ( these were prescribed for something else that were not needed. So far there is no improvement. Can you advise what Imshould do.. Because I am in pain now
