"The amount of BPA released from dental sealants or composites is extremely small and limited to a small number of products. The minimal exposure generally occurs within the first few hours after placement and then quickly reduces to virtually nothing. Once the material is placed and hardened, it becomes very stable. "

"CLINICAL PRACTICE ADVICE: 

To reduce the potential of any BPA being released from dental sealants, dentists should fully 

cure the sealants or composites according to manufacturer’s instructions. In addition, dentists can 

treat the surface layer by performing 1 of the following 3 procedures: 

1. use a mild abrasive, such as pumice, either on a cotton applicator or in a prophy cup; 

2. have older children and adolescents gargle with tepid water for 30 seconds; or 

3. wash the sealant surface for 30 seconds with an air-water syringe while suctioning fluids 

and debris from a child’s mouth. (Azarpazhooh and Main, 2008)"
