No. The amount of bisphenol A that comes from dental sealants has always been extremely small and limited to a few specific products. As well, this very minimal exposure occurs within the first few hours/days after placement, and then quickly reduces to virtually nothing.

The government’s report and recommendations places restrictions on the use of bisphenol A only in products for infants – such as baby bottles and infant formula cans. This is because the amount of exposure from these sources is relatively close to safety margins, and because of increased sensitivity in infants. No restrictions are planned for dental materials because they are well within safety margins.

The exposure from baby bottles is higher because formula is often mixed with boiling water. This very high level of heat causes more bisphenol A to leach out. This type of heat exposure does not occur in the mouth. Once the dental material is placed and hardened, it becomes very stable.
