Where can you get dental care for the very poor adult?

My mother needs dental care due to having severe acid reflux.She had a beautiful smile.She contracted a stomach virus and vomited several times,the acid from her stomach deteriated her right front tooth.She has half or less of it left.We live in Anniston,Alabama.My mother is on SSI which doesn't pay for the dental work she needs.Like veneers or somthing along those lines.We would love to see our mother smile again.
--------------------
Since she is on SSI she should qualify for Medicare or Medical (It might be called something else if you are in another state). A last resort would be something like Western Dental- where they have payment plans, but there dentists are not the best. Has she seen her regular dentist? There is not hurt in calling and asking how much something is and if they accept payment plans.
