Kelly I think a trip to the vet might be in order too. Before she calls she should check the inside of kitty's mouth, as Tubby and Peanut's mom suggested, because they will probably ask how it looks while she is on the phone with them. I worked in a dental office (for people ) for ten years. There is a condition called a "dry socket." That is when the original clot following an extraction has dislodged before the gum heals. This causes air to go directly to the jawbone area and is VERY painful. I have seen people in the waiting room practically crying. I don't know if this can happen to cats or not though. One of the things that can dislodge a clot is sucking on a straw or smoking. So far I have not heard of cats doing either. I don't mean to make light of this situation, though, so I'd encourage her to make that call.
