Hi, I Have A Huge Problem. I Went To The

Hi, I have a huge problem. I went to the dentist yesterday and they told me that I have pericoronitis. I was complaining of pain on my back wisdom teeth and the gums around them are swollen. The left side was horrible. I am prescribed antibiotics currently and she said that the way my wisdom teeth are coming in, I need to get them removed. Do I get them removed after the infection is gone or can I get them removed while the infection is still there? Also, since I have to get all four removed, how much will that cost?
