My son’s dentist has recommended dental sealants for my 7 year-old son, despite the fact that he’s never had a cavity. I have to call back tomorrow to talk to the dentist, but I am doing some research now to prep for the conversation.

It appears that these sealants last between 5 and 10 years, and they are primarily used on molars. These sealants – or many of them – contain BPA.

What is your experience with sealants? What is your understanding of the pros and cons?
