Does BPA leach out of dental sealants?
Several studies have reported that trace levels of bisphenol A (BPA) may be released from certain dental sealants, but only during a short time period immediately after application of the sealant. In addition, the highest level of BPA exposure reported from dental sealants is more than 50,000 times lower than levels shown to cause toxicity in animal studies. Based on these findings, human exposure to BPA from dental sealants is minimal and poses no known health risk.
