Sounds shortsighted (Score 1)

That sounds terribly shortsighted by the insurance companies. I have understood that dental care is one of those areas where you can save a lot by early treatment before the problems grow bigger. Or do they not cover even serious dental problems?

It is way too easy to let your teeth go unchecked even if it does not cost you that much to visit a dentist. Last year I finally visited a dentist after 7 years since the last visit so I know that from personal experience. And that did not cost me more than a nominal price (12 EUR or 17 US$) in public dental care (I live in Finland). At that time I promised to myself that I would get my teeth checked yearly, but this was year and a half ago...
