re: How do poor people go to the dentist?

Medicaid. LA Medicaid under the new "Bayou Health" plan just started paying for limited dental care with a dollar limit per year. Better than nothing.

Only issue at this point is that few private dentists have done the paperwork to accept payments from Bayou Health and therefore don't work with these patients yet. But there are exceptions including my wife's (no pics) practice in Prairieville.

Edit: If he makes too much for Bayou Health then maybe he should just pay out of pocket instead of expecting all his health expenses to be free. Most dentists will work out generous payment plans.
