Mercury poisoning, MS similar

To the editor:

The article "Gene flaw linked to autism" got my attention. I am researching the use of the world's No. 2 toxin that has been put into our mouths since 1826. Mercury has been placed into teeth only two inches from the brain. All the symptoms of mercury poisoning are the exact symptoms of multiple sclerosis, but instead of calling it mercury poisoning, it has been called MS since 1836. Mercury is toxic before putting it into a tooth, and it is toxic after being removed from a tooth. Why are dentists doing this? If you have MS, you cannot become an organ donor. Doesn't that make you wonder why? Something is being covered up.
