Dental Sealants and BPA :

Since BPA is sometimes found in sealant materials, parents may be hesitant to let their child receive this treatment. Fortunately, very small amounts of the chemical are released from dental sealants. After analyzing BPA release in 12 different dental sealants used across the U.S., the ADA found that the average sealant only released 0.09 nanograms of the chemical. The Environmental Protection Agency has proposed a limit of 1 million nanograms of BPA per day for a 6-year-old child, and dental sealants fall far below this threshold.

The ADA notes that children are exposed to a higher level of BPA through other common items, including food, drinks and cosmetics, such as shampoo. People of all ages are also exposed to BPA through the air.
