Does Prenatal Fluoride Exposure Lead To Lower IQ In Kids?


It’s no secret that fluoride has been a mainstay in the water supply for decades. It is added to drinking water, toothpaste, and even baby formula to help reduce tooth decay and strengthen teeth. But a new study from researchers at the University of Toronto suggests prenatal fluoride exposure may lower a child’s IQ.

What is Prenatal Fluoride Exposure?

Fluoride is a mineral that occurs naturally in many water sources, including rivers, lakes, and the ocean. It is also added to public water supplies to help prevent tooth decay. Although fluoride can be beneficial for dental health, too much exposure to fluoride – especially during pregnancy – can lead to many health problems in both mother and child.

Exposure to high fluoride levels during pregnancy can interfere with the development of the brain and central nervous system, leading to cognitive impairments later in life. Prenatal fluoride exposure has been linked to lower IQ scores in children and an increased risk of attention deficit hyperactivity disorder (ADHD). Fetuses are particularly vulnerable to the effects of fluoride because their brains are still developing.

There is no safe level of fluoride exposure for fetuses, so pregnant women must limit their disclosure as much as possible. If you live in an area with fluoridated water, talk to your doctor about alternative drinking water sources during pregnancy. And be sure to brush your teeth with non-fluoridated toothpaste and avoid mouthwashes that contain fluoride. Taking these precautions can help protect your child from the harmful effects of prenatal fluoride exposure.

How much fluoride does an expectant mother ingest?

Expectant mothers are advised to drink fluoridated water during pregnancy, as it has been linked to lower IQ in kids. However, it is unknown how much fluoride a pregnant mother ingests. A study conducted by the National Toxicology Program found that pregnant rats exposed to fluoride had offspring with lower IQs. The study found that the amount of fluoride ingested by the expectant mother was a critical factor in the lower IQs of the offspring.

Does prenatal fluoride exposure lead to lower IQ in kids?

According to a new study, prenatal fluoride exposure has been linked to lower IQ in kids.

The study, published in the journal Environmental Health Perspectives, found that children exposed to higher fluoride levels during pregnancy were likelier to have lower IQ scores than those not disclosed.

Fluoride is a chemical added to many public water supplies to prevent tooth decay. It is also found in many products, such as toothpaste and mouthwash.

Previous studies have linked prenatal fluoride exposure to adverse health effects, including impaired brain development. However, this is the first study to link prenatal fluoride exposure to lower IQ scores.

The researchers analyzed data from over 500 mother-child pairs from Mexico. They found that mothers with higher fluoride levels in their urine during pregnancy were more likely to have children with lower IQ scores at ages 4-6.

These findings add to the growing evidence linking prenatal fluoride exposure to adverse health effects. If you are pregnant, it is vital to be aware of the sources of fluoride exposure and take steps to reduce your exposure.

What are the long-term effects of prenatal fluoride exposure on kids?

Fluoride is a mineral found in water and many foods. It is also added to some dental products to help prevent tooth decay. Although fluoride can benefit oral health, too much exposure during pregnancy may lead to dental fluorosis in children. Dental fluorosis is a condition that causes white spots or streaks on teeth. In severe cases, it can also lead to pitting or crumbling teeth.

Exposure to high levels of fluoride during pregnancy has also been linked to lower IQ scores in children. A few studies have shown that children exposed to fluoride while in the womb had lower IQ scores than those not disclosed. However, it is essential to note that these studies are small and more research is needed in this area.

Although more research is needed, it is essential to be cautious when using products that contain fluoride during pregnancy. If you are concerned about fluoride exposure, talk with your healthcare provider.


The evidence seems overwhelming that prenatal fluoride exposure leads to lower IQ in kids. It is a severe problem, and it’s one that we need to start paying attention to. We must stop using fluoridated water and start warning people about the dangers of fluoride exposure during pregnancy. If we don’t do something about this, we’re going to see a decline in the average IQ of our population, and that’s not something we can afford to ignore.


Does fluoride affect kids?

According to a new study, prenatal fluoride exposure has been linked to lower IQ in children. The research, published in JAMA Pediatrics, found that every 0.5 milligrams per liter increase in fluoride in a mother’s urine was associated with a decrement of 3.15 points in IQ scores in her offspring.

Does fluoride change behavior?

It has been researched that the cells and tissues are impacted by fluoride, which eventually leads to changes in behavior in some cases.
