Where can I find a low cost dentist clinic or dentist in Ohio?

I really need to see a dentist clinic, but being a single mom with no dental coverage I buy drugs online can't really afford one. I am barely getting by as it is. I make sure my kids see their dentist on a regular basis (they have insurance) because I don't want them to be ashamed of their teeth, like I am. I am willing to make payments, but currently can only afford small payments (maybe $50.00/month). I am not looking for a free ride. Most dentists can't or won't accept that small amount for the amount of work I need done. I feel so ashamed that I don't smile like I used to.
