Goof: Just after the teaser, Mulder and Scully are looking at the dental radiographs. Scully points out that the man is "congenitally" missing a lower left bicuspid. It is impossible to tell if the reason why the tooth is no longer present is congenital from the radiograph. Congenital is a condition existing at birth.
