I'm surprised that health insurance companies haven't started offering "good brusher" discounts the way car insurance companies offer a "good driver" discount when you use their car data logging device/app.
I fucking hate this dystopian future we've already entered. It's only a matter of time until every car on the road is connected to the internet and has the "good driver" logging built-in and automatically sent to your insurer. They'll also know exactly where you've driven to and when via GPS. Then they'll offer you discounts on the restaurants and stores you frequently drive to, and everyone will love it and tell ME that I'm the crazy one...
People advertising such benefits are simply smarter than the victims of it. Same is true for loyalty coupons. Of course in the medium to long run you don't save a penny because advertisers know your price flexibility down to the last cent. You just fail to notice and have no reference to real values.
Most regular medical insurance isn't really insurance, in the usual sense. "Classical" insurance only pays out when something goes wrong, in defined amounts based on what's gone wrong. And while certainly insurers like to find ways not to pay out when you report a claim, there are usually far fewer gotchas with things like auto insurance, home insurance, event insurance, etc., than there is for medical insurance, where you could be denied coverage just because the "wrong" ambulance company took you to the hospital. Not to mention that anything that pays for preventative doctor/dentist/etc. visits isn't really "insurance".
But it's fine; we call it insurance anyway, and everyone knows what it means, so there's no problem.
“When you look at the dental insurance model, it doesn’t protect the patient from financial risk. It’s the opposite,” said Marko Vujicic, chief economist and vice president of the Health Policy Institute at the American Dental Association. “Once the benefit runs out, the $1,400 or whatever it is, all of that financial burden is on the patient. So it protects the insurer, they’re limited on their exposure.”
In other words, there is no real benefit to offering a "good brusher" discounts.
