Medical News Today -- A study has revealed that sealants and fillings used on children’s teeth may expose them to bisphenol A (BPA), says an article in the medical journal Pediatrics. The researchers say it is not yet clear whether this is hazardous to the long-term health of a child, as exposure does not generally last long. Dental sealants, which contain a variety of BPA derivatives are effective in preventing the majority of dental cavities in children and teenagers.
