Brandonsmama, with all respect, do you really want him to have "problems with lots of cavities"? The whole idea behind sealants is to prevent those problems from happening, closing the barn door *before* the horses get out, so to speak. Waiting until there are problems just tells you, ooops, shoulda got the sealants. It's too late then. And it's a lot suckier than sealants, for sure!
My latest analogy on it is "bring on the bacon double cheeseburgers, I haven't had enough heart attacks yet!" :LOL
No pressure, for sure, you are his mom and you have made your decision, just had to point out the flaw in the reasoning in case someone else reads and thinks, "yeah, haven't had any cavities, so why seal?" I totally don't mean to be obnoxious and hope it isn't perceived that way!
