Bisphenol A or BPA, the chemical compound that based on previous studies has been found to cause a number of health problems, may also cause tooth enamel problems in humans, according to a study published in the American Journal of Pathology.
According to the researchers at Universite Paris-Diderot, the incisors of rats become more fragile with a high probability of becoming damaged with low, daily doses of BPA. The analysis of the affected animals’ teeth showed characteristics similar to Molar Incisor Hypomineralisation, which is a condition where children’s teeth become extra sensitive and more prone to cavities. Molar Incisor Hypomineralisation is commonly found in the tooth enamel of about 18% of children between 6 to 8 years old.
What is the source of BPA, or Bisphenol A? The chemical can leach from the plastic containers and into food, snacks and water that humans eat daily. A 2003/2004 survey by the U.S. Centers for Disease Control found detectable levels of BPA in 93 percent of over 2,500 urine samples tested. In addition, with plastic containers almost everywhere, it is most likely that BPA has also contaminated the environment.
The National Institutes of Health (NIH) also found through animal studies that “BPA may cause adverse effects, such as obesity, behavioral changes, diabetes, early onset puberty, asthma, cardiovascular diseases, reproductive disorders and development of prostate, breast and uterine cancer.”
Europe banned BPA in materials used for babies’ bottles in January 2011 and in all food containers in France by July 2015. However, in March 2012, the United States Food and Drug Administration (USFDA) said that it did not find any proof that regular exposures to low levels of BPA are unsafe.
