There has been much talk about the dangers of ingesting BPA through plastic sippy cups and even water bottles that we bring on the go. BPA, also known as bisphenol A, is a chemical found in hard plastics of food and drink containers and acts in a similar way to estrogen, and other hormones in the body.
The Food and Drug Administration (FDA) had originally deemed BPA to be a safe substance, but recent studies have shown that this chemical has lead to disruption of normal hormone levels, possible brain and behavior problems in infants and young children, and an increased risk of cancer and heart problems.
Recently, researchers have tied enamel damage to early exposure to BPA. A team led by Ariane Berdal of the Universite Paris-Derot showed that rats that have been treated daily with low doses of BPA resulted in damaged enamel. The rats were observed during a 30-day development window where researchers exposed the rats to the doses of BPA. The earliest observations founds on the rats were white marks found on their incisors. On a macroscopic level, the teeth with white marks were found to have fragile and brittle BPA. On a microscopic level, the enamel showed a decreased level of crucial minerals, the teeth were more susceptible to cavities.
The damage found on the teeth of these rats is comparable to damaged tooth enamel found in 18% of children between the ages of 6 and 8. These researchers believe that enamel damage is another effect of BPA damage to the body. It is important to check products for a “BPA-free” label before they are bought. While the FDA has cracked down on plastics containing, be cautious when buying baby bottles, sippy cups, baby formula cans, and other products for young children.
