Cavietee, sobering advice. Do you see better work coming from some areas of the world rather than others? Better materials?
From what I know, at least getting a few crucial implants for anchoring dentures can ensure a decent fit. And don’t wait too long! The dental arch can atrophy and chewing muscles change sans teeth. My mom was always looking for bargains/alternative care, waited for years and was finally suckered into some shyster clinic that advertised. She looked ridiculous with overlarge teeth, they never fit, and chewing felt impossible. Total waste of money, and a significant percentage of her retirement savings were lost. She and my sister did this on the sly initially as they probably knew I’d disapprove.
In Oaxaca last winter someone staying at the same place was having a full set of extractions and implants. He was down there for many months, so had time for the full process.
My one dental experience in Taiwan decades ago was interesting. A crown, and it was functional for a long while, if less finely done than what replaced it later for aesthetic purposes. There can be differences overseas, chairs in a row, and at least back then, no finely crafted temps while work is in progress.
