Association between Children’s IQ & Fluoride

blog- Association between Children’s IQ & Fluoride

It is known that an optimal level of fluoride in water is safe and effective in preventing tooth decay by at least 25% in both children and adults. The content of Fluoride in water, however, has an impact on a Child’s IQ. 

Quoting an article from the “American Academy of Pediatrics”

Women living in areas with fluoridated tap water had higher mean urinary fluoride levels than those living in areas without fluoridated tap water (0.69 vs 0.40 milligram per liter, or a difference of about 0.30 mg/L). Adjusted results showed that a full 1 milligram per liter increase in maternal urinary fluoride was associated with a 4.5-point lower Performance IQ score in boys. There was no statistically significant association for girls. In the group for which self-reported fluoride intake from all sources was estimated, each additional milligram of daily fluoride intake was linked to a 3.7-point lower IQ score in boys and girls.

The above finding prompted some questions around Fluoride intake during pregnancy. 

Should pregnant women drink fluoridated water?

The answer is YES.

The American College of Obstetricians and Gynecologists, which focuses on the significance of good oral well being during pregnancy, recommends that women use fluoridated toothpaste.

The American Dental Association remains committed to the idea of fluoridation of public water supplies as an effective public health measure to help prevent tooth decay.

The report also stated there was a possible need for some women to reduce fluoride intake during pregnancy.

What to conclude from this study?

Fluoridation continues to play an important role in safely preventing dental disease when used within its recommended levels.  Dental disease is widespread, causing millions of lost hours of school each year. Children who experience tooth decay are more likely to have pain that makes it hard for them to eat, sleep, and learn in school. Simply by drinking water, Americans can benefit from fluoride’s cavity protection wherever they live, work and play.
