Dr. Hulda Clark did this, she removed the fillings and lives with holes, she says she must clean each and every tooth after each meal and I assume hot and cold will drive you bunkers! In Nature there are no too hot and no too cold!
I would probably suggest diamond rock plastic fillings over no filling at all, but my dentist will do what ever you ask and there are probably a few in your area as well, but don't ask your average death instructed dentist to do this for you, he/she will throw a holy fit as they throw you out and even possibly turn you in!!
