My Father-in-Law is my Dentist. I gotta vote YES.
He has been in the practice since the late 1960’s and swears that Fluoride in the water has improved the condition of peoples teeth.
Your Father In Law is absolutely right, but that won’t end the conspiracy kooks.
I’ve lived in places with floridated and non floridated water, and people, particularly children have abysmal teeth where the water is not floridated.
If your water isn’t floridated, your child will be subjected to floride treatments by a dentist to make up for it annually or semi annually.
Pier reviewed medical journals have proven the safety and efficacy of floridated water for over 50 years now.. in fact the whole reason that water supplies got floridated in the first place was because of the study of why some areas had people with far more healthier teeth that others... Turns out the places that had high floride naturally in their drinking water had healthier teeth, and no, no link to higher rates of cancer were found in these areas.
However the fear mongering that floridated water causes cancer has been going on ever since.
