as long as the rest of your application is stellar, it shouldn't make much of a difference. a person in my DDS program failed her part 2 and she still got acceptance and is now my classmate. and yes it showed her fail mark on her score report.
you need to remember that the NBDE part 1 and 2 is just a baseline assessment, and the real assessment of whether they will call you or not is based on your SOP and CV and resume. what you can bring to the program and why you would be a good fit for their school. i would rewrite the exam in 3 months, but i wouldn't delay sending out my applications to schools.
