How do I get my Dental Lab records? Please help!?

I had major reconstructive dental work performed by a dentist. For legal reasons I can not say more about the dentist other than she does not have the complete contents of my dental lab records. The dentist ordered 28 crowns and veneers from a dental lab. The lab will not release the records to me because under law, dental labs are "wholesalers" and are responsible only to their customer... the dentist. I want to know what is the material content of my veneers and crowns and more importantly in which country they were manufactured. Can anyone tell me if it is possible to get this information? Is their a government agency? I know dental labs are unregulated, but it seems like as a consumer I should be able to determine what was cemented in my mouth. I even offered to have another dentist take possession of the records and the lab said no. I went as far as I could with the BBB, but in the end they can't help because labs are "wholesalers" etc.. Please help if you can. W.
