Help my mom get her smile back

Please help my mom get her smile back, she is loosing all of her teeth because as a child her family didn’t have the funds to pay for a dentist. Unfortunately once she became an adult and was able to pay for a dentist from her own pocket, the dentist that worked on her ruined her teeth and made matters worst for her, because of this she has lost most of her molars and is now unable to chew her food right. This has been tough for my mom, she has lost her confidence because of her missing teeth and we want give her that confidence back. Please help her get her smile back.
