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.
Sealant on molars for 6 year old? My son is 6 years old, and I have a question about a recommendation his dentist made. His 6 year molars have come in, and his dentist is recommending that we put a sealant on each of these 4 teeth. My son has healthy teeth overall - though there was one spot where a cavity started about a year ago, but has not progressed and does not, so far, need treatment.
