Chemicals in Toothpastes Can Damage Fetal Brain

Scientists have found that pregnant women exposed to high levels of chemicals, namely triclosan, can make their fetuses at risk of disability.

New research shows that triclosan in toothpastes can interfere with blood flow to the uterus, causing fetal brain hunger. Whereas oxygen is needed for fetal brain development.

“We know these chemicals can lead to trouble, especially for pregnant women. But we do not know how many chemicals that can cause problems,” said Professor Margaret James of the University of Florida, according to Dailymail.

Triclosan is a strong anti-bacterial which was developed nearly 50 years ago.

Now it is commonly used in toothpastes, deodorant and hand washing soap, anti-bacterial soap and even some kinds of toys.

However, this material has brought concerns of the Food and Drug Administration (FDA) which has announced to review the security level of  ticlosan usage.

A recent study showed that triclosan may disrupt the enzyme that allows the estrogen hormone circulate in the womb.

Estrogen helps to open the main artery that carries oxygen-rich blood to the fetus. If too little, these arteries constrict and the oxygen supply will be exhausted.

Previous research has shown that antibacterial soaps containing triclosan and triclocarban are suspected to damage the reproductive organs, lower sperm quality, and production of thyroid and sex hormones.

Other studies also found that the triclosan compound in toothpastes which should prevent the growth of bacteria, instead causes the germs to be more resistant to antibiotics.

In addition, both compounds are also water-repellent or hydrophobic, tend to stick to the particles, resulting in decreased availability of process and damage the long-term transport facilitation in the water and air.

In fact, one study found that the accumulation of triclosan in water, causes pollution at beaches which ultimately threatens marine life.
