Are BPA laced dental sealants safe for your child?


BPA exposure has become a health concern after several studies linked the chemical to various health problems. The exposure to BPA, which is commonly found in plastic bottles, grocery cash receipts, can occur from the dental sealants recommended to prevent tooth and gum decay, as per a recent study.  Tens of millions of U.S. children are exposed to this toxic chemical when they receive dental sealants. Now being a parent you might be wondering whether it is safe to have dental sealants in your children? Here is a good news, health professionals stated that dentists can use the sealants safely in kids, if they make sure that they wiped or rinsed away residue after treatment.

What is BPA?
BPA is a plastic hardener and synthetic estrogen which is used to coat thermal paper and found in many kinds of plastics, including some water bottles and metal food can liners.

About the study
The study, published in Pediatrics, claims that the sealants have derivatives of BPA that turn into BPA on contact with saliva. The BPA exposure lasts for up to three hours after the dental sealant is applied.

The lead author of the paper, Dr. Abby Fleisch of Children’s Hospital in Boston revealed that

  • BPA does...

    form in the mouth after some dental sealants and fillings are applied. But it’s unclear how much BPA kids absorb from the dental sealants and whether this poses a health risk.
  • A quick wipe and rinse of the completed dental work immensely decreases the chances of risk
  • Scrubbing and rinsing sealants and fillings after they are applied removes 88% to 95% of the compounds that can become BPA

The team of toxicologists and dentists who reviewed the scientific literature for the report concluded that the benefit of the sealants to prevent tooth and gum decay in children was greater than the risk posed by brief exposure to BPA. Overall, the researchers believed that the benefits of the sealants outweigh the risks.

Though the report is not that worrisome for kids, but it cautioned that pregnant women should not get their dental procedures done during the pregnancy time, owing to risk of BPA exposure.  Rather they should wait until their babies are born.
