can't tell you how many times I have heard that line from a dentist. They must use it everyday on someone.

I have had allergies since I was a little kid, pretty sure since before i had any fillings. how many times I was kept home from kindergarten with swollen eyelids... so I am not real sure you can always blame it on fillings but certainly they don't help the situation.

There's nothing natural about methacrylates, the base of most all dental composite materials. And most composite materials are also manufactured to slowly leech flouride which is added to them also. I guess that is suppose to protect the composite while it erodes the calcium from the rest of your teeth and bones.

Dentists really are not very well educated sad to say. Very few of them seem to actually know the chemistry of the materials they work with and somewhere along the way it seems they were taught to assume no one else knows either. If someone made coffee cups out the same material they make composite fillings out they would be declared illegal.. due to baruim or thallium, or flouride.. whatever... and then also there's the swift business move that outsources so much plastic manufacturing to places like china... including dental composite materials... and of course lead has been found in a good number of those plastics coming from china, including dental materials...

anyway, you get the picture. talking to dentists about it has never brought an acceptable resolution for me. generally they will deny anything and everything.
