Surely exposure from composite resin falls off quickly over time and pales in comparison to our constant environmental exposure to plasticizers. Any data on this?
If the BPA derivative exposure in this sealant is low enough compared to usual daily exposure the benefit of having an effective sealant is too great to overlook. Let's say (for example)usual daily exposure is 1, the sealant adds 0.0000000000000001. Considering how devastating teeth problems can be this cost is a no brainer to pay.
