BPA exposure and new concerns for oral health

Your Jacksonville, FL dentist knows that parents have long worried about the effects of BPA on children. Now, a tooth enamel abnormality in children–molar incisor hypomineralization–has been shown to result from exposure to the industrial chemical bisphenol A.

BPA is a hormone-altering chemical linked to adverse health effects in humans of all ages. It appears in many plastic and resin household products like baby bottles, sippy cups, and infant formula packages.

It is now understood that BPA impacts dental enamel, the hard covering that protects teeth. Molar incisor hypomineralization causes white or brown opaque spots on an affected child’s permanent first molars and incisors and can lead to sensitivity, pain, and cavities. Recent published data show that MIH affects up to 18 percent of children ages 6 to 9 years. Although the cause is unclear, it appears to have an environmental origin as in BPA exposure, according to the study authors.
