Choice of Material for Crowns

[Guest guest]

I'm waiting for permanent crowns & learned today that there are no

dental restoration materials that I'm compatible with. I was given

two choices, considered to be least likely to be problematic:

a) a porcelain-type that has to be affixed with metals (probably

involves nickel - & ???)

a newer quartz/plastic type that is carved into shape from a block

I've initially said to go with " b " , because I don't want metals at

all and don't want interference with chelation. However, I was

told " " wears down over time against an opposing surface that's

harder.

There are no 'good' options, and my dentist understood my concerns

with absorbing plastics given their connection with endocrine

disruption, etc.

Does anyone know anything about this newer material and have any

experience with it? Am I irrational about having metals that would

connect porcelain crowns? I'm highly sensitized to the metal aspect

of the porcelain crown, and I guess that's why my dentist called. I

don't think he wanted to make any judgments for me on this. (Even

temps are really annoying ... I want to rip them out, and there's 6

of them in place right now!)

Thanks,
