M.P.
well teething they generally dont have coughs, I think she probably caught something at the Urgent care when you took her for her fever. I would say you could just try to comfort her with cold compress, and let her play with a frozen teether if she likes those. If she likes baths, bath her and do some massage with baby oil or lotions. This will calm her till you can get back. I would say with a persistent fever and cough your looking at a illness rather than teeth.
