My kid got a cavity. Just had it filled recently. It cost me a bundle and makes me rethink getting dental insurance. It also makes me rethink what I need to do to ensure my two little guys do the very best they can with their pearly whites.

Of course, they need to brush. If I had it my way, they'd brush after eating, every time they eat. But this is hard since they spend a few hours each week day in school and I can't realistically mandate classroom brushing after snacks and lunch. I can be vigilant at home, though. I can hover like a helicopter over them, judging their respective techniques. Let's face it: Kids left to their own brushing devices will cheat, even if unaware their form is not exactly right.

My boys can floss -- and they do -- but as a team, we can do better. We can also swirl around a little mouthwash. And use this cool pink solution the dentist gave us (well, sold us) that marks the hiding places of food bits. And my favorite: We can cut down on sugary, sticky, sweet treats. We've got them down to a pretty good minimum but there's always room for improvement.
