Thank you for your email . I have diligently worked against the use of fluoride in our drinking water, and , in fact, successfully had it banished from our water in Oyster Bay , NY over 30 years ago when my children were growing up. . Dr. James Harrison
, DDS, https://www.theintegrativedentist.com/author.html worked diligently to get the fluoride removed from the drinking water in Boca Raton, Florida. I highly suggest his book, The Periodontal Solution.
You will also find good information about the dangers of fluoride at the link below:
