Yeah, I read about Aluminum toxicity long ago and stopped using aluminum when cooking. Also dentist are one of the professions that suffer high suicide rates...when you get rid of mercury and you get...

I became curious about the composition of porcelain crowns and called one of the manufacturers. I was told their porcelain was pure ceramic. Thanks. I called another and asked what their ceramic was made out of. Porcelain I was told. I called another and asked what their porcelain ceramic was made out of. Natural products. Knowing that mercury was “natural” I went to scientists other than manufacturers. Natural porcelain ceramic is made from clay B kaolin specifically B which is 45 percent aluminum oxide. Oh! So porcelain crowns are really aluminum. The aluminum does come out of the crown and I have personally seen some tragic cases of poisoning from dental porcelain ceramic aluminum crowns. Obviously not everyone has violent reactions, but when they occur, it is not a happy site [sic].

I don't know if this type of aluminum is toxic, I have a crown....sigh
