The wire for my braces is just barely too long?

The wire on the left side sticks out just a tiny bit. Like, maybe half a millimeter. But it pokes my cheek and really hurts, particularly when I eat. I put some wax on it but I've discovered the wax comes off whenever I eat or brush my teeth. Will the dentist clip a wire that's so barely too long or will I just have to keep the wax on it?
