The article already has one example: “Juneau, Alaska, voted to remove fluoride from its drinking water in 2007. A study published in the journal BMC Oral Health in 2018 compared the dental records of children and adolescents who received dental care for decaying teeth four years before and five years after the city stopped adding fluoride to the water. Cavity-related procedures and treatment costs were significantly higher in the latter group, the study found.”

Our neighborhood has the Magical Chicken Wing bush. The dog thoroughly inspected it for months afterwards, and still checks on it now and then just in case.
