Whenever there is a volcanic eruption, you will find that it is always the fluoride in the ash that causes the teeth of wildlife and farm animals to CRUMBLE and FALL OUT. It is only the fluoride that is to blame for this damage. It causes bones to break. But somehow dentists believe if you put this bio accumulative poison in a toothpaste tube or in tap water it becomes a miraculous substance that benefits everyone's teeth. How STUPID do dentists expect everyone to be? Fluoride bio accumulates in the teeth and bones forever

"It [fluoride] also binds with calcium in the blood stream and after heavy exposure over a period of days makes bones frail, even causing teeth to CRUMBLE."

"The ash is toxic — the fluoride causes long-term bone damage that makes TEETH FALL OUT and bones break."
And dental fluorosis due to chronic fluoride overexposure seems to be a little more than just cosmetic. See "Comparative Toxicity of Fluorine Compounds".

"Mottled teeth are not only disfiguring in appearance but are so defective in structure and strength that they often have to be replaced? by false teeth? at an early age."
When did this fact change? This was known back in the 1930's.
H. Trendley Dean was the father of fluoridation. To paraphrase Dean's findings, "As children's teeth disintegrate, they may have fewer cavities". Trendley Dean admitted under oath on? a witness stand that his early data gave ZERO evidence that increasing fluoride concentration in the water supply reduced tooth decay.
