Momentum health declining procedures

It is with great disappointment that I had to learn that an in hospital procedure was declined by momentum health. I need the help of an maxilla facial surgeon one tooth due to trauma and the other due to infection the procedure was booked in theater but momentum health declined it under the heading of dental care but this is not done by a dentist neither could a dentist do it. I keep on hitting a wall with the dental department that keeps on reading the same line to me dental work is not covered. My question is this if I am in a car accident and need reconstruction to my face and teeth will momentum cover this? Likely not but I wont know that until it is too late. I should not be too upset as the Dr office did warn me when they hear momentum health that they will be very unlikely to pay but not paying anything was a great dissapointment.
