Fluoride is a mineral that has been added to many public water supplies for decades in an effort to improve dental health.

While fluoride may be beneficial in preventing tooth decay, recent research shows that prenatal exposure to fluoride may have serious health risks, such as hypothyroidism and decreased intelligence. In this article, we will explore the dangers of prenatal fluoride exposure and the potential harm it can cause to both the mother and the developing fetus.

What is Prenatal Fluoride Exposure?

Prenatal fluoride exposure refers to the exposure of a developing fetus to fluoride during pregnancy. Pregnant women who consume fluoridated water or use fluoride-containing dental products are at risk of exposing their developing fetus to fluoride.

In addition, fluoride exposure can also occur through the air, food, or workplace exposure.

How Does Fluoride Affect the Thyroid Gland?

Fluoride is known to affect the thyroid gland, which is responsible for controlling metabolism and regulating hormones in the body. The thyroid gland absorbs iodine, which is essential for the production of thyroid hormones.

However, when too much fluoride is present in the body, it can interfere with iodine absorption and lead to hypothyroidism.

Studies have shown that prenatal fluoride exposure can lead to a decrease in thyroid hormone levels in both the mother and the developing fetus.

This can result in a host of health problems, including developmental delays, cognitive impairment, and reduced IQ levels.

How Does Prenatal Fluoride Exposure Affect Intelligence?

Research has shown that prenatal fluoride exposure can have a detrimental effect on intelligence levels in children.

A study conducted in Mexico by researchers from the University of Toronto found that children born to mothers with higher levels of urinary fluoride during pregnancy had lower IQ scores compared to children born to mothers with lower levels of fluoride exposure.

Another study conducted by researchers from the National Institutes of Health (NIH) found that prenatal fluoride exposure was associated with a decrease in IQ levels in children aged 3-4 years old.

The study further found that the higher the fluoride exposure during pregnancy, the greater the decline in IQ levels.

What are the Other Risks Associated with Prenatal Fluoride Exposure?

In addition to hypothyroidism and decreased intelligence, prenatal fluoride exposure has been linked to a number of other health risks. These include:.

Impaired fetal brain development
Increased risk of attention-deficit/hyperactivity disorder (ADHD)
Increased risk of autism spectrum disorder (ASD)
Increased risk of preterm birth and low birth weight
Increased risk of preeclampsia

How Can Prenatal Fluoride Exposure be Prevented?

The best way to prevent prenatal fluoride exposure is to avoid consuming fluoridated water and using fluoride-containing dental products during pregnancy.

Pregnant women can also take steps to reduce their exposure to fluoride by using a water filter that removes fluoride or drinking bottled water that is fluoride-free.

If you live in an area where the water is fluoridated, it is recommended that you speak with your healthcare provider to determine the best course of action to protect yourself and your developing fetus from the harmful effects of prenatal fluoride exposure.

The Bottom Line

Prenatal fluoride exposure may have serious health risks, such as hypothyroidism and decreased intelligence. Pregnant women should take steps to reduce their exposure to fluoride to protect their developing fetus.

If you are concerned about your fluoride exposure during pregnancy, speak with your healthcare provider to determine the best course of action for you and your baby.
