Dentist Recommendations in Texas Who Would Do Free or Cheap Work if We Have Insurance?

My husband needs quite a bit of work done on his teeth. We have insurance through work & we have a dental discount plan but we wouldn't be able to afford to pay what was left of the bill. They do hurt often & he's VERY self conscious & never smiles. I don't want him to have to spend the rest of his life in pain & worrying about this problem. So is there any dentist in Texas who would be willing to do cheap or free work???? Thanks so much!!!!
