Like most of you, I have health insurance. Like most of you, my health insurance says it covers dental work. As with most of you, this is basically a fiction. Insurance companies are famously stingy at the dentist. Whenever I leave my dentist’s office, he and I follow a ritual. He solemnly informs me he will first bill my insurer, and I agree that would indeed be prudent. Then, about six weeks later, I get a letter notifying me that my insurance company has completely paid for all but $328 of my $341 bill. So you can imagine my excitement when I recently got a letter from AARP, informing me it has a dental plan for which I qualify, as a new member in good standing.
