A new study by Dr. Katia Jedeon, of the French National Institute of Health and Medical Research (INSERM), and colleagues found exposure to the chemicals bisphenol A (BPA) and vinclozolin may interfere with hormones responsible for the growth of dental enamel.
“BPA and vinclozolin have been identified as endocrine disruptors (EDs) in numerous studies. This means they can interfere with hormone functioning in mammals, increasing the risk of reproductive problems, cancer, births defects, and various other conditions.
Dr. Jedeon and colleagues note that previous animal studies have indicated that EDs may be related to a condition called molar incisor hypomineralization (MIH), which is estimated to affect up to 18 percent of children aged 6-9 years.”
Exert caution with:
*  Certain plastics and resins, many of which are used for food and drink packaging, which may contain BPA
* Vinclozolin (a fungicide) used to protect vineyards, orchards, and golf courses.
