i do believe the local dentist posted a ton of actual science based evidence to support the notion that fluoridation has a direct benefit for healthy teeth.  what you read are a bunch of opinion pieces put out by groups opposed to science based evidence, much like the anti-vaxers.  

am i 'wrong', i don't believe so but i know folks like you cannot expose themselves to actual science because you simply have your mind made up.  can i alter you opinion?  i would not even attempt that by repeating science based evidence as i am dead certain you would find an outrageous way to ignore the data and the factual conclusions.
