L.U.
What kind of insurance do you have?
My son has insurance through the state. (DSHS) His teeth were B.A.D. The orthodontist said they were bad, took pictures, did measurements of all of the gaps/flares of his teeth and sent them off to the state to see if they would cover it because it was medically necessary.
DSHS sent back that they would not cover it.
Orthodontist took MORE pictures and measurements and sent it BACK to DSHS.
DSHS decided to cover them.
My amazing orthodontist then covered what wasn't by DSHS (about $1,000)
You could go to another orthodontist and ask them for their opinion as well. If everyone is saying they are not medically necessary and you feel like they are then you need to work out a payment plan.
Good luck.
