Just when the Bisphenol A in baby bottles controversy was looking settled, a new health concern has been raised in the form of dental fillings. Many dentists use materials that contain BPA as a sealant and questions are being raised about the viability of these materials.
Last week the Canadian federal government announced that it would be banning the use of bisphenol A in plastic baby bottles as the chemical has been linked to early puberty in girls, breast and prostate cancer, and attention deficit and hyperactivity disorder.
AdvertisementDarryl Smith, the outgoing president of the Canadian Dental Association said BPA in fillings was very small and could not cause any health issues in that quantity. Health Canada has revealed that at the moment there is no hazard posed by BPA fillings.
However Aaron Freeman, policy director at Environmental Defence is not convinced saying there are plenty of studies to illustrate the problem of BPA fillings. With the furor over this material refusing to die down dental fillings may very well be the next target.
