Are you trying to suggest that dental patients rather that dentists are responsible for any hg caused health problems because they allowed hg to be placed in their teeth .What happened to the concept of informed consent? Most people don't enen know their "silver" fillings are 50% hg.If dentists called them mercury fillings (they should) who would get them ? Many people have 90 I.Q.s and not much education . Are they supposed to be able to read scientific journal articles written by MIT PhDs?
Patients have a right to rely on their dentists not to put highly toxic substances in their mouthes.
I have a degree with honors from Berkeley and I did'nt know my fillings were 50% mercury.
