I think I've got an infection in my gum - it's sore and my cheek is quite swollen up. The problem is that there isn't an emergency dentist available locally and I have to travel on Monday. We do have quite a good walk-in centre for minor injuries and illnesses, however, which will be open on Sunday. Given that I probably need antibiotics, does anyone know whether a walk-in is likely to be prepared to deal with this and prescribe?
