Many dentists have used a tooth-colored amalgam filling that contains bispenol A (BPA) as opposed to using a metal amalgam for filling cavities.
Author Nancy N Maserejian, of the New England Research Institute, points to study from the New England Children’s Amalgam Trial where they can review data comparing children with metal fillings compared to children with composite or tooth-colored fillings. The study was conducted to determine if there were any behavioral effects from the use of these materials.
It was found that there were higher rates of depression and stress with children who had fillings with BPA than with metal fillings.
The concern for BPA came up in a report by a National Toxicology report in 2008 over possible effects on the brain and prostate gland in fetuses, infants and children exposed to BPA a chemical used to line aluminum cans since 1960. In 2010 the FDA reported the same concerns.
According to Dr. Joel Berg, president of the American Academy of Pediatric Dentistry, these findings are part of much larger examination of BPA in materials of which dental amalgam represents a very small portion. Also, the chemicals used today are much safer than the ones used during when the report was done.
It is still important to treat tooth decay especially with children. Todays amalgams are very durable and effective.
