      Those fillings can actually actually be used in big cavities that are close to the nerve, where with traditional fillings your doctor would require to do a root canal. They also don’t get washed out and need to be replaced like the normal ones.

      Mercury poisoning was a problem in the past when the doctors had to themselves mix mercury with silver. Modern vitals already contain right proportions and don’t have such risk.

      IMO I don’t understand the need for ban. It only affects the individual, kids won’t generally have cavities like that.

      Feels like the push is to eliminate a cheap alternative and to push root canals and crowns when those are not necessary. I actually not long ago had dentist replace my amalgamated filling with a crown and that was the worst decision I did. It made my tooth sensitive and now that dentist’s suggestion is to do root canal. But if course that will destroy the crown and would need to do one again.

      Because for some people, the white fillings pop off their teeth like crazy.

      I have never had any white filling from any dentist last more than a year. Most never make it to the six month stage. And yet, I have had amalgam fillings last for 30+ years. They just hold onto my weak-ass teeth in ways that the white fillings cannot.

      Probably for the old fart dentists? My dentist, three generations now, said no one has used in over a decade maybe two.
