New studies show the sealants and resins used by your dentist to repair or seal teeth in order to protect from them from cavities break down into BPA or Bisphenol A. In light of this most recent study the North American dental community responded by saying that wiping away the excess sealant or resin will reduce the risk of BPA exposure.
However experts in the dental community did say that pregnant women should avoid these kinds of dental procedures until after they have delivered. They also suggested that young children should have proper brushing and flossing etiquette reinforced by parents. Brushing and flosing 2 – 3 times a day and particularly after meals. Good dental hygiene care should limit the risk of cavities and dental work performed in the more susceptible years of childhood.
In recent years BPA has sparked alarm after several studies linked the chemical to health problems, prompting many manufacturers of plastic bottles, particularly those used by children, to change their formulations to exclude the substance.
In January, federal Food and Drug Administration officials called for additional research, explaining that the agency had “some concern about the potential effects of BPA on the brain, behavior and prostate glands of fetuses, infants and children.”
In the U.S., depending on age, between 20 percent and 40 percent of children had been treated with sealants between 1999 and 2004, due to the aggressive efforts to improve dental hygiene the percentage of children at risk is potentially much higher. The team of toxicologists and dentists who reviewed the scientific information for the report concluded that the benefit of making sure children’s teeth are protected against decay was greater than the risk posed by brief exposure to BPA.
