I have asked the dentist to furnish me the product data sheets for the temp crown and the zyrconia crown. Monday I will call back and also ask for the data sheets for the crowns 10 years ago. This will help the biomedical lab with testing. If I don't get what I want on Monday or at least a call back as to why, I will contact the Arkansas State Board of Dentistry, where we have a friend as executive director. I love my dentist, but I am not going to put up with being mistreated. His receptionist has been saying that nothing is different from 10 years ago to recently. She has been quite hateful and has said that she is saying what my dentist told her to. When I talked again with her on Wednesday, she said my dentist wanted to talk to me. She asked for my phone number. That was funny because they always call me every 6 months for an appointment reminder.... I have had the same number for 35 ish years. The dentist never called back.... This is day 3. Anyway, she stated that it still wasn't the crown, but that everything was DIFFERENT...the temp crown and real one from 10 years ago and the more recent ones were each different from the other... I said all it takes is one element that I am allergic to in common! The medical lab in Dallas wants those product data sheets. My medical doctor said it is like a bottle of bleach in his cleaning closet. He could call the manufacturer, and they would be obligated to send him the sheet. He said that is true with anything in his office! So why am I having trouble getting them? Why am I having trouble at all? It looks like they would be bending over backwards to help me!!!! I seem to be getting worse each day. I am not producing much saliva and don't get hungry..... I am concerned.
