Yeah true, but anything I use will most likely need that for the bonding agent. I am not sure about glass ionomers either, I hear some people have issues with those as well. One biologic dentist advised me against them. I already have a few in my own mouth, which he thinks maybe causing some of my issues. That I do not know. Could be some of the composites though.

I figure that at least the bonding agent will be much less than having an entire composite. It will also be underneath and not so much exposed to hot fluids etc.

NOt sure what else I can do, I seem to react with whatever goes in!
