Hi Jason, thanks for the info and link. I had already bought something for my gum problem a while back from overseas. I guess it worked "ok", but nothing miraculous. My gums don't bleed, but they are tender and apparently I do have the disease, but it's not overly evident as yet. It can impact a person's health too apparently. I don't know if I'd order anything else from overseas at this stage, I'm out of my debt at the moment on my credit card. Thanks though.

Also, aluminium oxide is used inside the body for the artificial joints also and is apparently highly biocompatible. It's been used for many years. Zirconium is apparently very biocompatible and I hear there is an actual dental material called zirconium oxide which is supposedly the most biocompatible material out there. Though I have not heard of any dentist using it here.

I may not be able to get cerec if the cost is going to be too much. I too have heard they can range from 1000 dollars per tooth. There is NO way I could do that (1000 nz dollars). SO im making sure before I commit to any of it. I made a number of enquires and most here charge about 850 - 1500 depending on size/depth of the tooth needing to be filled.

Also got in touch with an overseas dentist in Australia, who uses cerec. He only uses two materials in his surgery that he thinks are the most biocompatible. One is the cerec porcelain and the other is a composite called Heliomolar. He doesn't use anything else. He says there are some patients who react to almost anything and everything and he said that he's had to pretty much limit it down to these two materials as according to him, he feels they are fine with just about everybody.

His website is - http://www.shdc.com.au/ if you're curious at having a look. He's into oral toxicology too, so the fact he uses cerec should be a pretty good indication that it must be "ok".

All porcelain restoratives cost about the same amount. No matter which one you get.

Thanks for keeping us posted and yeah sure, if you do get a crown done in cerec, I will be most interested to hear how you feel with it and about it. You can also wait for a while before you had straight into amalgam removal, and see if you notice ANY odd reactions with the cerec crown before committing to getting your amalgams done with it.

Just a thought.
