Tolerable Upper Intake Level (UL)
of Fluoride for Fetuses

The CDC's Division of Oral Health ignores babies in the womb,
so here the fetal UL has been added to Table 2 of the CDC's
Recommendations for Using Fluoride to Prevent and Control Dental Caries in the US:

from CDC Table 2
Note: the UL for everyone under 9 years old is
based on weight: 0.10 mg/kg/day.

When a pregnant woman drinks 3 cups of fluoridated water,
she consumes 0.5 mg of fluoride. Fetal fluoride levels
average two-thirds of maternal levels, therefore
her unborn child receives a fluoride dose
over its Tolerable Upper Intake Level
.

When she drinks 7 cups of fluoridated water, her baby in the womb is exposed to about 0.8 mg of fluoride – a dose over the daily UL for a 6-month old infant.

    The Institute of Medicine referenced by the CDC explained:
  • In the unborn fetus, "sensitivity increases due to active placental transfer, accumulation of certain nutrients in the amniotic fluid, rapid development of the brain." (See Fluoridated Amniotic Fluid, pages 50-51 of Pregnancy and Fluoride Do Not Mix.)
  • "As intake increases above the UL, the risk of adverse effects increases."
  • "The term adverse effect is defined as any significant alteration in the structure or function of the human organism or any impairment of a physiologically important function."
  • A fetal UL would be "significantly lower." [Especially because a fetus weighs less than 3 kg earlier in pregnancy.]

During pregnancy, woman are encouraged to drink more water.

Reality Check

The words fetus or fetal are not mentioned in any of
the seven pages cited in the CDC's main fluoridation page.

The only mention of pregnancy: "Use of fluoride supplements by pregnant women does not benefit their offspring." (Recommendations for Using Fluoride to Prevent and Control Dental Caries in the United States. MMWR, August 17, 2001)

Fluoridation promoters say not to worry, because the only known adverse effect from a chronic intake of fluoride above the UL is "moderate enamel fluorosis," which the IOM selected as the critical adverse effect for infants and children. That's "because the cosmetic effects of the milder forms of enamel fluorosis are not readily apparent," said the IOM.

Claiming dental fluorosis is the only adverse effect,
is like tobacco promoters claiming yellow teeth
are the only adverse effect of smoking cigarettes.

The IOM did not consider fluoride's adverse effects on the fetal GI tract or brain, despite the fact that defects in tooth enamel have been correlated with impaired brain development. (See Developmental Defects Increase with Fluoride Levels in Water in Pregnancy and Fluoride Do Not Mix.)

The CDC has also failed to report the association between fluoridated water and premature birth, even though the agency has stated that preterm birth is "the leading cause of long-term neurological disabilities in children."

More lack of CDC credibility:

School Water Fluoridation

The CDC said fluoride levels in school drinking water systems be 4.5 times higher than in communities!

What's more, up to 6.5 ppm (mg per liter) of fluoride was allowed!!

If an 8-year-old drinks 4 cups of school water fluoridated at 5.0 mg/L, he would ingest 4.7 mg of fluoride – more than twice his Tolerable Upper Intake Level.
