The Food and Drug Administration on Tuesday announced it will begin the process of pulling prescription fluoride drops and tablets for children off the market. The supplements are usually given to kids at high risk for cavities.
The federal government and some state legislatures are increasingly drawing attention to what they claim are the risks associated with fluoride, a mineral that’s been used for decades in community water systems, toothpastes and mouth rinses to prevent tooth decay.
Dentists fiercely contest the notion that the harms of fluoride outweigh the benefits.
Obviously education about brushing and flossing and a healthy diet help more, if the family is able to afford the food and toothbrushes and regular dental care. But in areas where (natural or added) fluoride levels in the water are higher (within a limit of 1.5 ppm, twice what is set for when fluoride is added), there is observed to be less tooth decay and better overall dental health even when controlling the data for the elements you cited.
