My friend was talking about this recently. He is trying to put together the money to get a new tooth fitted, and mentioned that there is talk of having insurance cover replacement teeth for young people due to the fact that not having teeth can severely weaken the jaw over the course of your life. Not such a big deal when you're 80 and your teeth are falling out, but when you're 25 it has potential to become a big problem.
I guess my question is why would insurance care? If the bone in your jaw weakens and causes severe problems, it'll likely be your medical insurance that covers it.
I can't see a dental insurance giving a crap.
This is US/Canada specific of course. Any country that has single payer dental/medical coverage would care.
Not to put words in his mouth, but I think the above poster was referring to having medical insurance cover said dental costs because the loss of bone in the jaw would cause other medical complications down the line in young people.
That's how I took it, but don't dentists normally put the implants in? If dental insurance is paying for the implants and medical insurance is paying for the bone damage, there isn't a lot of incentive for the dental insurance to pay for expensive implants.
