Does South Dakota bestow affairs of state abet for those short Dental Insurance?

My boyfriend works in iowa but is a lives in south dakota and we can return with cheap dental work done at a dental school but he wont drive 2 hours for it, and there is a "base on income" local dental clinic here in iowa where he works but i doubt theyd permit him go there since he's a SD resident. i call a dentist in SD and the total with everything he wants done will be close to $1000.00!
he has to get central cleaning and at least 2-3 teeth pulled.
any help will be great!
