my dentist got false information regarding my dental plan?

ok i need to have 2 Porcelain crowns for my 2 front teeth, it is a two visit process i was told the dental office requires half my portion on the first visit and half on the second... and i am fine with that but the amount they said the insurance company would cover seemed off, so i contacted the company and i was right the dentist said that porcelain crowns were not covered so i would need to pay the difference between porcelain and metal, and they said i was only covered at 50% the insurance said they dont not cover for porcelain crowns for posterior teeth and that i was covered at 80% obviously they have already overcharged me AND they will expect an additional payment next week.. sure they said i'd get reimbursed any over paid amount but i dont really have free 500 to fork over regardless of whether or not i'll be getting it back... so the question is what should i do if the dentist wont accept my report from the insurance company? i already have started with them so switching dentists is not an option since i have temp crowns and they already took the molds and are ordering the new crowns... plus i'm pretty sure i would still need to pay even if i switched

I would keep all documents that you insurance has sent you and who the person you talked to at the insurance office. Also you have to remember that you only have a certain amount that the insurance is going to give you 80% on. So find out what that is. Most insurance companies are either $1500 a year or $2000 a year and then anything after that you will pay out of pocket. So make sure that you have meet your amount already. Remember you get that per year. So when did you husband have work and how much was it. Also call you insurance company back and find out what your yearly cost is that they will help pay the 80% on. Then I would go from there. Good Luck
