<<Disclaimer: Verify this information before applying it to your situation.>> Dear Fellow List Serve Members, Sorry this is late. I've been having trouble posting to the list. Re: Linda's question "Is there anyone out there who works in the dental field or who has the time to get hold of a list of companies that supplies materials to dentists, to contact them for gf status of standard products, the way we do foods and common drugs?" The Clan Thompson Pocket Guide to Gluten Free Pharmaceutical Products DOES contain a list of companies that supply materials to dentists along with the gluten status of some standard products and phone numbers to contact for verifcation. You can see the list on our webpage: http://www.freeyellow.com/members/clanthompson/index.html Regards, Lani K. Thompson Stoneham, Maine USA
