And it can't be applied on a smooth surface, so sealant won't prevent cavities from forming between teeth, even if the surface of the teeth have been sealed.

Bisphenol A or BPA-based epoxy resins are widely used in the manufacture of commercial products, including dental resins, polycarbonate plastics, and the inner coating of food cans.
