question: Hi, I can't get into my dentist for a few days. I was prescribed Nitrofurantoin for a urinary track infection. Can I use that for now. My face has a golf ball coming out of my cheek! I have heard that a dentist is going to tell me to take anitbiotics before they can do anything anyway. This way I can at least take the swelling and infection down. I am in SO MUCH PAIN.
