BOSTON (CBS) – According to a study from the University of North Carolina, children who do not drink tap water, which typically contains fluoride, are much more likely to have tooth decay.

On the other hand, children and adolescents who do drink tap water are more likely to have elevated levels of lead in their blood.

The public has become increasingly concerned about the water supply especially after the water crisis in Flint, Michigan. And even if just a small number of kids are affected by lead, it can have long-lasting devastating effects.

That said, tooth decay, which affects one in five preschoolers and more than half of all teens can lead to pain, infections, loss of teeth and can be costly.

So the government needs to make sure that public drinking water is clean and safe.

And in the meantime, if you have concerns about your tap water, you can buy a home testing kit.  And parents should make sure kids are getting regular dental check-ups and using fluorinated toothpaste.

  1. You write about this poor quality and bizarre small study but don’t make any mention of the Sept 2017 publication of a major NIH/NIEHS/EPA sponsored multi-million dollar, multi-year study that found that when fluoride exposure is prenatal in doses consistent with doses in the general population of ‘optimally’ fluoridated communities, IQ is lowered by up to 6 points on a dose-response trend line?

    The findings of this rigorous study by renowned experts at top American and Canadian colleges validate the findings of dozens of human and hundreds of laboratory studies – prenatal and/or youthful exposure has a subtle impact on brains that manifest as lowered IQ, increased learning disabilities, or mood disorders. Also released in 2017, the 2011-12 NHANES figures that over half of American children have the visible evidence of fluoride poisoning during childhood, i.e. dental fluorosis. Why not report on that? More than one in five American teens have at least two brittle stained teeth that will require veneer or crowns due to this poisoning.
