The second statement is meant to be the justification for the first. 

Justification usually works for the person justifying, but not so much for the person they justify to. 

When I hear "I haven't been to the dentist because I don't have insurance" I usually smile and say nothing.  What I'm thinking is, "but you still have teeth, right?" 

If so, those teeth are still the responsibility of the owner.  Often the owner has a diet full of high fructose corn syrup and carbonated beverages and personal habits that rarely include brushing and never include flossing.

Dentistry is expensive (mostly because of dental insurance, but that's a probably another day's tirade) but the least expensive thing you can do in my office is come in every six months for us to get a look at your teeth.  If you're a low risk due to habits, diet and genetics then God bless you and you probably don't need to be seen even that often. 

But your teeth are still your responsibility (or your problem, depending on how you feel about them)...even if you don't have insurance.
