1 BPA does indeed form in the mouth after some dental sealants and fillings are applied. BPA can be found in the saliva three hours after dental work is completed. It's not at all clear whether this poses a health risk.  A quick wipe and rinse of the completed dental work vastly decreases whatever risk there might be.
What to Expect During a FILLING. 1  Local anesthesia â at the beginning of your filling procedure, you may be given local anesthesia to numb the area around the tooth. 2  Tooth decay removal â then the dentist will cut through the enamel using a drill to remove any decay. After the dentist removes the decay, the dentist will shape the space to ready it for the filling. Etching â for a bonded filling your dentist will etch the tooth with an acid gel before placing the filling.
