It was estimated that this use of uranium causes about 2,000 cases of cancer per year. I've since mentioned this to many dentists, but none of them had ever heard of this. Cecil, I'm counting on you to find out what's going on here. Preferably before I need more dental work. In one of those classic wacky moves, manufacturers once upon a time put uranium in dental porcelain to give crowns and false teeth that certain glow.
Real teeth have natural fluorescence.
If you shine a black light on your teeth they gleam a brilliant white. To give dental work the same glow, the use of uranium in dental porcelain was patented in 1942. The timing of this was suspicious. You have to wonder if those Manhattan Project scientists, toiling over crucibles of hot uranium, got to thinking, hey, if this atom-bomb thing flops, we can always go into teeth. The glow imparted to false teeth by uranium was not a consequence of radioactivity.
