Do the math and you'll find dental insurance is a ripoff. Additionally, while some people can't afford much of anything, others who complain about the cost of dental care, buy things as or more expensive because they value those things more: Big screen TV for example. They don't value dental care as much, until they are in pain. Then they expect an entitlement. People pay for what they want. Dental insurance is a subsidy, not insurance. Delta Dental of CA has over $600,000,000 invested in tradable securities. They didn't pack away that much money giving away dentistry for free.
