Fluoride Linked to Worse Kidney Function in Teens, but Don't Flip Out

In the 1950s and 1960s, states and cities in the U.S. began adding fluoride to drinking water supplies, following decades of research and anecdotal reports showing that fluoride could prevent tooth decay, especially in children.

Parts of the UK also receive water that has been through a fluoridation process, particularly in the Midlands and the north.

And water fluoridation continues to be endorsed by public health and dental organisations as one of the most worthwhile and cost-effective health policies ever implemented.

(In the U.S., fluoridation is thought to cost an average dollar per person, far less than the medical costs of treating even one cavity).

But some scientists have also argued that fluoridation as it exists today could have unintended, harmful health effects.

Maybe it’s not that chronic low-level fluoride exposure leads to poorer kidney function, but that people with preexisting poor kidney function are less able to metabolise fluoride.
