I had stage one of a root canal on am upper premolar on Wednesday, and its still a little painful - my dentist hasnt quite finished drilling the roots out. Thats scheduled for next week. Question is, my cheek seems to be a little swollen now, even tough the pain has subsided compare to yesterday... Im worried that there might be a slight infection there.I have some Flucloxacillin tablets - 500mg. Will taking them minimise the risk of another abscess forming?

The swelling is because of infection, and you need to take antibiotics like Amoxicillin or flucloxicillin and anti-inflammatory
