Phosphorous was selected by Mother Nature to be the element responsible for holding together all genetic material. As its phosphate form, it is the basis for life. But a small modification of phosphate will take that life away quite efficiently - Sarin. Oh, yes - it's time for The Dreaded Chemistry Lesson From Hell!
Oral bacteria attack teeth in more ways than we knew. Bacteria that sequester phosphate in the ocean also do so in the mouth. Since phosphate is an integral component of enamel, its removal can weaken the teeth and make decay more likely. So keep flossing, folks!
