Any Great Dentists in BA?

I'm asking for an older woman from the USA who wants to come do implants/crown etc. work in Argentina because it's too expensive in the USA. Anyone done this here or know someone who has? Looking for a dentist of high repute/competence who is reliable, obv she's worried about coming to a foreign country to do this.
This info might help others on this forum too. Thanks!

PS feel free also to dm me if you don't want to say in public
