So I hear! Sadly i'm British, If British (notoriously lax sense of humour) and Aspergers one must laugh at ones own jokes as not to be lost.
I found a great surgery and have had one replaced just yesturday (in a hurry) with the plastics compound, then at christmas I will switch them to the Porcelain. Just had to get them out and at present I haven't noticed any detremental side effects. They blocked the back of my mouth, paid careful attention to the suction around the tooth, allowed me to see the tooth free from the amalgam, and let me take a break to swish, rinse and chill! All in all, I am feeling positive about the appointment, and glad to get the metal out before christmas, the second appointment is in a couple of weeks. I upped my vitamin C a few days ago and I'll eat plenty of antioxidant rich foods.
Patience is most certainly a prerequisite for dentisty. Mine were asked to explain in detail the stages of the procedure, the contents of the injection, how they go about safely depositing disposed materials after dental procedures and other relevent information. I had already researched this information and needed to check they covered all the posts. They also had to convince me several times not to have them pulled out. I ended up sketching what could happen if I did. Ridiculous I realise, but it all helped and I hopefully won't have to go back for a loooooong time after this is all completed.
Comparitevly, my friend underwent a root canal without flinching. No issue, grin and go. Amazed.
