How Food Packaging May Damage Teeth
A new study by the French National Institute of Health and Medical Research (INSERM) finds that early exposure to two chemicals -- vinclozolin and bisphenol A (BPA) -- often found in fungicides and, more alarmingly, in food packaging may cause irreversible damage to children's teeth. These chemicals, it seems, may affect hormones responsible for the growth of dental enamel, putting children at greater risk for tooth decay.
Numerous past studies have identified both vinclozolin and BPA as endocrine disruptors (EDs), meaning they can interfere with hormonal function in mammals. Vinclozolin is a fungicide used in vineyards, orchards, and golf courses, while BPA is employed in the production of certain plastics and resins often used in food and drink packaging.
"Tooth enamel starts at the third trimester of pregnancy and ends at the age of 5," said the study's lead author, Dr. Katia Jedeon, "so minimizing exposure to endocrine disruptors at this stage in life as a precautionary measure would be one way of reducing the risk of enamel weakening."
