Are braces considered a medical expense as far as child support is concerned?

My husband's ex-wife just mailed us a letter serving as some sort of "bill" for $1000 toward his daughter's braces. She's 13 and we carry dental insurance (which covered a big portion of the cost). She included a copy of the divorce decree which mentions medical expenses to be split between them, but I didn't think that included orthodontia (since that is considered a cosmetic procedure and not a necessity). And before anyone gets nasty stating that my husband should "take care of his kids" etc. He does - he pays child support on time - is not ONE CENT behind and buys the extras for the kids when needed. He's no deadbeat. We are just on a tight budget, have a daughter of our own, both work 45 hours plus a week in order to pay for ALL the kids' needs and all the while, she works part time, carries a LV purse, gets her nails done weekly, has a MAID come in to clean her house. Ever since she had a new baby with her live-in BF she expects us to pay for more. We can't pay $1K for this

Don't pay it like you said it is not a necessity unless it is state in his decree then you do not have to pay this is cosmetic a lot of dental insurance co. won't pay any of the cost over the xrays.
