Actually, Fluoride is safe in appropriate doses, but like anything else, it is possible to get too much of a good thing. After decades of research, the main risk linked to fluoride overuse is dental fluorosis, a cosmetic condition that kids can develop if they're exposed to excessive fluoride when they're too young.
Fluoride can directly effect on your teeth. It is really dangerous for your gums and teeth as well. I got this information by a good professional dentist in Diamond Bar. My personal experience is very good at "gurzdental.com" and "deltadentist.com". If you want good treatment and advice regarding dentistry then these are best places to visit.
A good friend of mine, who works as a research assistant in the medical field, told me that there have been some studies showing that fluoride, even in the small doses we get in our water and toothpaste, can add up and cause brain damage. I know that fluoride is technically a toxin, but it's been completely accepted by most public health experts for minimal use. Is there anything to this? I can't find much information about it, but I feel like her position gives her some authority on the subject. Do they even sell toothpaste without fluoride?
