Infection keeps spreading

I need prayers for my darn tooth. The infection is still spreading and I have kept running a low grade fever non stop now. I can hardly open my mouth due to the swelling and now the redness and swelling is covering about 3/4 of my throat. I have lived on Vicodin since Thursday. I need to go to town and get some yogurt but not really wanting to go out looking like I do. The dentist said not to worry unless it affects my breathing and then go to ER. OK unless it gets better there is no way he can do a root canal when I can open my mouth jst part way!
