This is an example of a reply I got from a biologic dentist in Australia who uses cerec, when I asked him about it.

Cerec is an excellent material and as tooth-like a material as we have found. It also wears at the same rate as tooth and expands and contracts the same as tooth (we expose our teeth to variations in temperature from 0-55 centrigrade). Being porcelain it also does not leach out its components like amalgam or composite. Non-metal is also important from a bio-electrical perspective ( remember our muscles and nerves work by transmitting tiny electrical currents.

Another dentist Dr Wayne King, biologic, uses cerec also and said to me, out of any choice, cerec woudl be my best bet, both biocompatibility wise, and also the strength of the material itself.

Another dentist who has used it for 18 years tells me he's not heard of ONE adverse reaction so far.

I mean this is just bizzare. Who do we trust?
